Revision Project: PDM Page A Description: Proximity detection module (PDM) is a wireless detection and distance measurement sensor operating at 2.4Ghz. 3 of 11 1. PROJECT DESCRIPTION Proximity Detection Module is an RF module designed to measure the distance between two nodes. The module uses Atmel AT86R233 phase difference measurement function in order to relate change of signal phase with distance. The module operates in the 2.4 GHz band in order to communicate between two paired nodes. The sensor was designed in order to be integrated with Hetronic standard systems. By adding a PDM module in a transmitter and receiver one can choose the location where the operator has to be in order to operate the system. The user can choose to either operate the system when he is less than a configurable distance to the receiving PDM node or else when he is far away by the selected distance.

CONFIGURATION PARAMETERS When connecting with a serial interface to the PDM module one can configure the RF parameters and edit the communications parameters of the sensor. An example of the parameters available is shown below. Figure 3: PDM configuration parameters Addresses can be configured via the serial interface and go up to a sixteen bit value. The address for the receiver has to be the same as the transmitter address plus one. The receiver address has to be updated as the reflector short address in the transmitter and own short address in the receiver.
