Capacitive Touch Switch Sensor TTP223 Red-Board Module
The TTP223 Capacitive Touch Sensor is an IC-based sensor module that provides a single integrated touch sensing area of 11 x 10.5mm with a sensor range of ~5mm. The module has an on-board LED which lights up when the sensor is triggered offering a visual representation.
When the module is triggered the output will switch from its idle LOW state to HIGH. Solder jumpers allow for reconfiguring the mode of operation to be either active low or toggle output.
Specifications:
- Operating voltage: 2.5V – 5.5V
- Operating current: 6uA (idle), 16mA (active)
- Sensor area: 11mm x 10.5mm
- Max sensor range: ~5mm
