TTP223B capacitive touch sensor - Arduino

The TTP223B is an Arduino-compatible capacitive touch sensor. It offers adjustable sensitivity through the value of capacitance C1. Can be used as a touch button or physical contact detector Great forArduino, Raspberry Pi, AVR, PIC projects. It features a supply voltage2-5.5V, uses the TTP223B chip, responds in 60 ms, has SIG, VCC, GND leads.. Measurement is by capacitive method. The module has dimensions of 24 mm x 24 mm, mounting holes of 2 mm in diameter and a LED indicating touch. Sensitivity of the sensor depends on the value of capacitance C1 - the lower the value, the higher the sensitivity of the module! Specification:.
