The module is based on the touch-sensing IC (TTP223B) Capacitive Touch Switch Module. When a capacitive load (such as a human hand) is in close proximity to the sense-pad, the sensor detects the change in capacitance and activates the switch. In the normal state, the module output is low. When a finger touches the corresponding position, the module output is high, If not touched for 12 seconds, it will switch back to low-power mode.1. Low power consumption2. Can easily replace the traditional button switches3. Four M2 positioning holes for easy installationJust power it with 2V - 5.5V DC and touch the pad to activate the sensor. These touch switches interface easily to any project - with or without a microcontroller.Custom sense-pads can be made from nearly any conductive material and these sensors can detect touch through thin layers of non-conductive materials such as glass, plastic, fabric or even wood. So you can make this sensor hidden in the wall, tabletop or other places, which allows you to remove the conventional push-buttons. 1. Power supply for 2 ~ 5.5V DC2. Control Interface : A total of three pins (GND, VCC, SIG)3. GND → Ground4. VCC → Power supply5. SIG → Digital signal output pin6. Power ON Indicator: Green LED7. Response time(Low power mode): 220ms8. Response time(Touch moide): 60ms9. Size: 2.4 x 2.4cm (L x W)
