The microwave sensor displacement signal processing module program analysis using single chip, high reliability. Circuit board has 16 sensitivity adjustment, sensing distance adjustable 0.3 - 10m.

The microwave sensor module is non-contact displacement probe-type modules, RFI ability, independent of temperature, humidity, light, air, dust impacts can be installed in a certain thickness of the plastic, glass, wood and other non-metallic shell which facilitate their application to control a variety of products or equipment above.

16-level sensitivity adjustment: the circuit board with 4 0 1 2 3 marked the connection point.
Short circuit in accordance with the following four connections, adjustable 16-level sensitivity, so that in the 0.3 - 10m sensing distance adjustable. 4 a connection point break, the nearest sensor, at 0.5 meters.

4 trigger modes to adjust: the circuit board there are two connections marked with 45 points.

1: 00 Touch-type trigger can not be repeated:
Detect moving objects, high signal output 3 seconds after the stop, delay 2 seconds and then test to detect moving objects further out than 2 seconds, followed by cycling. Until less than a moving object detection, high signal output to stop.

2: 01 Repeatable trigger touch-type, delay time of 2 seconds:
Detect moving objects, high signal output 2 seconds, 2 seconds of time, the module frequency of 30 times per second, not live testing, to detect if an object moving again, time to delay 2 seconds, Until less than a moving object detection, High signal delay 2 seconds after the stop.

3: 10 repeatable trigger touch-type, delay time of 10 seconds:
Detect moving objects, high signal output of 10 seconds, 10 seconds time, the module frequency of 30 times per second. Not live testing, to detect if an object moving again, time to delay 10 seconds, until less than a moving object detection, High signal delay of 10 seconds after the stop.

4: 11 repeatable trigger touch-type, delay time of 20 seconds:
Detect moving objects, the output 20 seconds kind of high signal within 20 seconds, the module frequency of 30 times per second.

Note: After sensitivity and trigger mode selection, the microcontroller needs power reset to implement the new options.

When sensor is triggered, relay will conduct.
