TTP223B Digital Touch Sensor Module - Blue

Description

Low power consumption Can replace the traditional key With four M2 screw holes, easy for operation TTP223 Capacitive Touch Sensor is a very useful addition for projects or applications where a conventional mechanical button or switch is not an ideal choice. This low-cost, low-power module can easily add a single capacitive touch input to any of your projects. It has a working voltage range of 2V to 5.5V and hence can be used with Arduino as well as any other 3.3V microcontrollers as well. The sensitivity can be adjusted by the capacitance (0~50pF) outside.
