2 .The sensitivity can be adjust by blue potentiometer

3 .Working voltage : 3.3 V -- 5 V

4 . Double output mode, the digital output is simple and more accurate analog output.

5 .Set the fixed bolt hole, convenient installation

6 .Small board PCB size: 3 cm * 1.6 cm

7 .Power indicator light (red) and digital switch output indicator light (green)

8 . comparator adopted LM393 chips, work stability

Interface specification (4 wire):

VCC —— external 3.3 V to 5 V

GND —— external GND

DO —— small plate digital output interface (0 and 1)
