5.1 Data Format
5.1.1 Format
There are two data types – Data 1, Data 2. The duration time for each data is 610us
Data 1: The duration time of High Level is 400us,
The duration time of Low Level is 210us.
Data 2: The duration time of High Level is 210us,
The duration time of Low Level is 400us.
5.1.2 Preamble Format
The preamble is 1 byte. There are 8 bits in the preamble. It is made up of 4 high levels (610us) and 4
low levels (610us) as below figure. It is transmitted from high level.

5.1.3 Data Rate Analysis
5.1.3.1 Data Rate is 1.64Kbps
5.1.3.2 There are 8 bytes every transmission. The total is 64bits. The duration time for each
transmission is 610us * 64 +x= 100ms.
5.1.3.3 If repeatedly transmit multi-group data, then the transmission duration time is 610us * 8 *
7=34.16 ms for each additional data. The preamble does not repeatedly be transmitted in each
data.
One cycle （transmit times 100ms）

7. Product Operation
7.1 Receiver
7.1.1 Key Function
7.1.1.1 There is one slide switch to select C/F unit.
7.1.1.2 There is one slide switch to select ID A, B, C.
7.1.2 When Power on or reset the LCD will full display for 3 seconds, the unit start to work.
7.1.3 The unit will detect the temperature and humidity every 30s.
7.1.4 Indoor Humidity Calculation and Display
7.1.5 Indoor Temperature Display
7.1.6 The outdoor temperature and humidity will be displayed when the signal is picked up, and the High/Low
temperature is displayed at the same time.
7.1.7 Display of high and low outdoor temperatures is to be a rolling 24-48 hour value as follows:
7.1.8 Trend lines (increasing decreasing steady)
7.1.9 RF433 Reception
When power on the receiver, the unit will turn on the RF module to looking for the RF signal, the
RF433 reception bars cycles (i.e. one bar, two bars, three bars…….one bar, two bars … etc.) This
continues until the unit receives a valid signal or for maximum 6 minutes if no signal is captured.
7.2 Transmitter (FCC ID: RNERF100XTX)
7.2.1 Key Function
7.2.1.1 A C/F button (search button) is added inside the transmitter.
7.2.1.2 A slide switch with A, B, C position is to select A, B, C channel. The factory default setting is A.
7.2.4 The unit will detect the temperature and humidity every 16s.
7.2.5 Outdoor Humidity Calculation and display in the receiver
7.2.6 Outdoor Temperature Display in the receiver
