It requires only a minimum number of external components and provides an integrated and calibrated temperature sensor. Power supply is provided by a small solar cell, an ex-ternal energy harvester, or an external 3 V backup battery. An energy storage is installed in order to bridge periods with no supply from the energy har-vester. The module provides a user configurable cyclic wake up. After wake up, the internal microcontroller reads the status of the temperature sensor and optional set point dial. A radio telegram will be transmitted in case of a significant change of measured temperature or set point values or if the external occupancy button is pressed. In case of no relevant input change, a redundant retransmission signal is sent after a user configurable number of wake-ups to announce all current values. In addition to the cyclic wake-up, a wake up can be triggered externally using the input for the occupancy button or the internal LRN button. The firmware can be configured to use different EEPs according to the availability set point dial and occupancy button. Features with built-in firmware  Pre-installed solar cell  On-board energy storage and charging circuit  On-board LRN button  On-board TX indicator LED  Calibrated internal temperature sensor  Input for external occupancy button and set point dial  Configurable wake-up and transmission cycle  Wake-up via Wake pins or LRN button  Support for humidity sensor module HSM 100 Features accessible via API Using the Dolphin API library it is possible to write custom firmware for the module. The API provides:  Integrated 16 MHz 8051 CPU with 32 kB FLASH and 2 kB SRAM  Integrated temperature sensor  Various power down and sleep modes down to typ. 0.2 µA current consumption  Up to 13 configurable I/Os  10 bit ADC, 8 bit DAC

See also 3.8.2 and 4.1. 3.3.1 GPIO supply voltage The IOVDD pin of EO3000I is internally connected to DVDD. For digital communication with other circuitry therefore a voltage of 1.8 V has to be used. While the module is in deep sleep mode the microcontroller with all its peripherals is switched off and DVDD, IOVDD, and SWPWR are not supplied. If DVDD=0 V and IOVDD is not supplied (e.g. while in sleep mode), do not apply voltage to ADIO0 to ADIO7 and the pins of the serial interface (SCSEDIO0, SCLKDIO1, WSDADIO2, RSDADIO3). This may lead to unpredictable malfunction of the device.

These settings are checked at every wake-up. Wake-up cycle time CW_0 CW_1 Wake-up cycle time NC GND 1 s ±20% GND NC 10 s ±20% NC NC 100 s ±20% GND GND No cyclic wake-up Redundant retransmission Via CP_0 and CP_1 an internal counter is set which is decreased at every wake-up signal. Once the counter reaches zero the redundant retransmission signal is sent. CP_0 CP_1 Number of wake-ups that trigger a redundant retransmission GND NC Every timer wake-up signal NC NC Every 7th - 14th timer wake-up signal, affected at random NC GND Every 70th - 140th timer wake-up signal, affected at random GND GND No redundant retransmission A radio telegram is always transmitted after wake-up via WAKE pins! After transmission the counter is reset to a random value within the specified in-terval. According to FCC 15.231a) a redundant retransmission at every timer wake-up to determine the system integrity is only allowed in safety and security applications! In this case the total transmission time must not exceed two seconds per hour, which means that a combination with a 1 s wake-up cycle time is not allowed! If applied in other (non-safety, non-security) applications a minimum of 10 s be-tween periodic transmissions is required. In addition the device has to comply with the lower field strength limits of 15.231e). The limited modular approval of STM 330C / 332U / 333U is not valid in this case.

These values are calculated, the accuracy is about +/-20%! The performance varies over temperature and may be strongly reduced at extreme temperatures or short transmit inter-vals.
USER MANUAL V1.05 © 2013 EnOcean | www.enocean.com STM 330 / STM 331 / STM 330C / STM 332U / STM 333U User Manual V1.10 | Page 22/33 STM 330 / STM 331 / STM 330C / STM 332U / STM 333U 4 APPLICATIONS INFORMATION 4.1 Using the WAKE pins The logic input circuits of the WAKE0 and WAKE1 pins are supplied by UVDD and therefore also usable in “Deep Sleep Mode”. Due to current minimization there is no internal pull-up or pull-down at the WAKE pins. When STM 33x is in “Deep Sleep Mode” and the logic levels of WAKE0 and / or WAKE1 is changed, STM 33x starts up. As the there is no internal pull-up or pull-down at the WAKE0 pin, it has to be en-sured by external circuitry, that the WAKE0 pin is at a defined logic level at any time. At time of delivery a jumper is connected between WAKE0 and UVDDext. WAKE1 provides an internal 1.8 MΩ pull-up. See figure below. EO3000IWAKE0WAKE1UVDDUVDDextSTM 33xWAKE1WAKE0GND1M81M8LRN ButtonJum per installed at time of delivery When the LRN button is pressed WAKE1 is pulled to GND and a teach-in telegram is trans-mitted. As long as the button is pressed a small current of approximately 1 µA is flowing. It is possible to connect an additional external button in parallel between WAKE1 and GND if a different position of the button in the device is required. WAKE0 is connected to UVDDext via a jumper at time of delivery. If the module is mounted onto a host PCB the jumper has to be removed. The circuitry on the host PCB then has to ensure that WAKE0 is always in a defined position. There are two ways to use WAKE0:  Connect WAKE0 to UVDDext and connect an external button between WAKE0 and GND. As long as the button is pressed a current of 1 µA will flow.  Connect a 3 terminal switch and switch WAKE0 to either GND or UVDDext. In this case there is no continuous flow of current in either position of the switch.

The sensor is part of the EO3000I IC and measures the chip temperature. Therefore it is important to provide a good thermal con-nection of the IC to the environment by ensuring sufficient ventilation of air inside the housing. Only then the measurement will represent the ambient temperature. Depending on the design of the housing a delay between ambient temperature changes and measured temperature value will be seen. 4.3 Set point control and occupancy button In order to control the set point, an external potentiometer has to be connected as shown below. In addition this figure shows how to connect the occupancy button. 4.4 Combination with humidity sensor module HSM 100 The humidity sensor module HSM 100 extends the functionality of STM 330 / STM 331 / STM 330C temperature sensor modules. HSM 100 contains an internal calibrated humidity sensor. It can be plugged onto STM 33x modules via the 20 pin connector. For details please refer to the data sheet of HSM 100. Heating of the chip due to its current consumption is negligible as the chip only consumes 200 nA while in sleep mode. Temperature measurement every second is not recommended as in this case ef-fects of heating of the chip might become visible and accuracy is reduced.

Since the expected transmission range strongly depends on this system conditions, range tests should categorically be performed before notification of a particular range that will be attainable by a certain application. The following figures for expected transmission range are considered by using a PTM, a STM or a TCM radio transmitter device and the TCM radio receiver device with preinstalled whip antenna and may be used as a rough guide only:  Line-of-sight connections: Typically 30 m range in corridors, up to 100 m in halls  Plasterboard walls / dry wood: Typically 30 m range, through max. 5 walls  Ferroconcrete walls / ceilings: Typically 10 m range, through max. 1 ceiling  Fire-safety walls, elevator shafts, staircases and supply areas should be considered as screening. The angle at which the transmitted signal hits the wall is very important. The effective wall thickness – and with it the signal attenuation – varies according to this angle. Signals should be transmitted as directly as possible through the wall. Wall niches should be avoided. Other factors restricting transmission range:  Switch mounted on metal surfaces (up to 30% loss of transmission range)  Hollow lightweight walls filled with insulating wool on metal foil  False ceilings with panels of metal or carbon fiber  Lead glass or glass with metal coating, steel furniture The distance between EnOcean receivers and other transmitting devices such as comput-ers, audio and video equipment that also emit high-frequency signals should be at least 0.5 m. A summarized application note to determine the transmission range within buildings is available as download from www.enocean.com.

The module is optimized to operate using small amounts of harvested energy, such as can be collected by a small solar cell exposed to ambient light. The module transmits short radio packets comprised of control signals, (in some cases the control signal may be accompa-nied with data) such as those used with alarm systems, door openers, remote switches, and the like. The module does not support continuous streaming of voice, video, or any other forms of streaming data; it sends only short packets containing control signals and possibly data and is typically powered by a solar cell in ambient light. The module is de-signed to comply with, has been tested according to 15.231(a-c), and has been found to comply with each requirement. Thus, a finished device containing the STM 330C / 332U / 333U radio module can be operated in the United States without additional Part 15 FCC approval (approval(s) for unintentional radiators may be required for the OEM’s finished product), under EnOcean’s FCC ID number. This greatly simplifies and shortens the design cycle and development costs for OEM integrators. The module can be triggered manually or automatically, which cases are described below. Manual Activation The radio module can be configured to transmit a short packetized control signal if triggered manually. The module can be triggered, by pressing a switch, for example. The packet contains one (or more) control signals that is(are) intended to control something at the receiving end. The packet may also contain data. Depending on how much energy is available from the energy source, subsequent manual triggers can initiate the transmission of additional control signals. This may be necessary if prior packet(s) was (were) lost to fading or interference. Subsequent triggers can al-so be initiated as a precaution if any doubt exists that the first packet didn’t arrive at the receiver. Each packet that is transmitted, regardless of whether it was the first one or a subsequent one, will only be transmitted if enough energy is available from the energy source. Automatic Activation The radio module also can be configured to transmit a short packetized control sig-nal if triggered automatically, by a relevant change of its inputs, for example. Again, the packet contains a control signal that is intended to control something at the re-ceiving end and may also contain data. As above, it is possible for the packet to get lost and never reach the receiver. However, if enough energy is available from the energy source, and the module has been configured to do so, then another packet or packets containing the control signal may be transmitted at a later, unpredictable time.
