Battery motion sensor with ambient temperature measurement rH-P1T1

The rH-P1T1 module is a combination of motion sensor and ambient temperature sensor. Low-current passive motion sensor detects a person by registering changes in infrared radiation. Change of motion sensor signal and temperature is asynchronously transferred to the system. The temperature reading is transmitted in defined time intervals, when the temperature changes by a predetermined value and when motion is detected. Communication with the server is done via radio. Typical applications include lighting control, heating control, ventilation control and operation in the security system.

The rH-P1T1 module is represented by an object, which consists of one input and one output of the binary motion sensor. The detection of a person generates a logical state of '1' on the output. In idle mode, the output is the logical state '0'. The temperature output due to the sensor housing is burdened with inertia.
