Module Description:
This module adopts imported touch keys dedicated chip, strong anti-interference, touch sensitive, can penetrate through plastics, glass, wood, etc. insulator (except liquid), the module can be set to two modes, trigger mode and lock mode, so conducive to everyone the development of different products, the module can be used with microcontroller to control, it can also be directly connected to control relay module.

Module parameters:
Voltage: 3- 5V (smaller voltage sensing distance smaller voltage 3- 5.2V )
Current: Standby 2uA / operating current 2.17mA
Dimensions: Diameter 2CM (round)
Output Current: 3- 5V / 8mA
Output level: default low (L), when the work is high.
Sensing distance: 5V voltage, sensing distance 5 mm .
Middle PCB board with blue LED.

Induction distance:
Default 5 mm, permeable insulator sensor control, prohibiting the installation of metal place by themselves can set Tap or self-locking mode, the default shipping is tap (non-locking) mode.
