Motion Transducer Configuration 

The motion transducer (detector) is on PIR Home Sensor models only and uses a PIR array 
sensor for the detection of human motion in a room. Due to the sensitive electronics used in 
the PIR motion detector, the Home Sensor is designed to behave as follows: 

•

 

For 2 (two) minutes after power is first applied to the device, the PIR motion detector is 
disabled. This is required for the PIR transducer output to stabilize and avoids false 
detections. 

•

 

For approximately 5 (five) seconds after a radio transmission, the PIR motion detector is 
disabled. The operation of the radio causes the PIR transducer to produce false positives 
so a 

“

cool down

”

 period is required after each Tx. 

The Home Sensor runs a simple state machine for reporting whether or not motion is detected. 
To conserve battery usage, the Home Sensor only reports motion when it is first detected and 
when motion has not been detected for a configurable Grace Period. 

Note:

 The PIR transducer is designed to detect motion so if a room is occupied but the 

occupants are not moving, the sensor may report “No Motion” after the Grace Period 

(see 

Section 3.4.7.1) expires. 

Table 3-18 shows a list of motion transducer configuration registers.
