Capacitive Button TTP223
PRODUCT ID: SEN-TOU-001
The heart of this capacitive touch sensor is TTP223. It has an on board LED indicator to show when sensor is triggered. In the normal state, the module output is low, with low power consumption. When a finger touches the sensor, the module output is high. If sensor is not triggered for >12 seconds, it will automatically switch to low-power mode.
You can use this sensor behind surfaces such as plastic, glass, or non-metallic materials. As long as your finger comes close enough, not necessarily touching, the sensor will pick up and trigger an output.
