Description

This device uses your body as part of the circuit.  When you touch the sensor pad, the capacitance of the circuit is changed and is detected.  That detected change in capacitance results in the output changing states.

The module is based on a touch-sensing IC (TTP223B) capacitive touch switch module. In the normal state, the module output low, low power consumption; When a finger touches the corresponding position, the module output high, if not touched for 12 seconds, switch to low-power mode.

Features:

  • Low power consumption
  • Power supply for 2 ~ 5.5V DC
  • Can replace the traditional touch of a button
  • Four M2 screws positioning holes for easy installation
