Overview: 

This capacitive sensing module can sense changes in an approaching human body or other capacitive body through any non-conductive medium (e.g. glass and plastic) and transmit the corresponding sensing signal. It can be used as a touch sensor switch, or as a body sensor or toilet seat sensor. 

Characteristics: 

◇ Single-channel capacitive touch sensor module.

◇ Digital output high and low levels. 

◇ 3-wire structure (GND, OUT, VDD). 

◇ Key output is completely dithered.

◇ 2.7V ~ 5.5V working voltage.

◇ Supports power-on detection function (i.e. the presence of human body can be detected normally during power-on). 

◇ Factory calibrated sensitivity, can support sensitivity customisation, and good sensitivity consistency, no need to stick conductive cloth. 

◇ Built-in baseline updating algorithm, sensitivity is not affected by changes in ambient temperature and humidity. 

◇ Built-in hardware and software logic compensation algorithms, so that changes in ambient temperature are not affected by long key presses. 

Application Scenario:

◇ Replacement of mechanical switch.

◇ Switching switch.

◇ Human body sensing and toilet seat sensor.

◇ Light control switches.

◇ Human-machine interface toys and interactive games.
