Description:
1. Working voltage: 5v-20v(DC） Static current: 65uA.
2. Automatic trigger. When the body enter into the active area of sensor, the module will output high level
(3.3V). When body leave out, it will output high level lasting for time T, then output low level(0V). Delay
time T can be adjusted by potentiometer R1.
3. According to the position of jumper cap, you can choose non-repeatable trigger mode or repeatable
mode.
L: non-repeatable trigger mode. The module output high level after sensing body, then when delay time
is over, the module will output low level. And during high level time, the sensor doesn’t sense body anymore.
H: repeatable trigger mode. The distinction from L is that it can sense body until body leaves during the
period of outputting high level. And then it starts to time and output low level after delaying T time.
4. Induction block time: the induction will stay in block condition and do not induce external signal at a little
time (less than delay time) after outputting high level or low level
5. Initialization time: the module needs about 1 minute to initialize after powered on. During this period, it
will output high or low level alternately.
6. In consideration of feature of this sensor, when body get close or away from edgewise side, the sensor
will work with high sensitively. When body get close or away in vertical direction, the sensor can’t work
well, which should get your attention. Sensing distance is adjusted by potentiometer.
We can regard this sensor as a simple inductive switch when in use.
