1. Capacitive sensing technology: enabled by the AT42QT1070 IC, this touch sensor features a non-contact detection and sensitivity to the human body while eliminating the need for manual physical buttons.
2. I2C communications: communication interface is I2C enabled, allowing ease of wiring and connection.
3. 12 channels: 12 single-touch keys are available per sensor, allowing for a wealth of creative applications.
4. Extended temperature range: sensor can operate in temperature ranges from -25 to 85 degrees Celsius.
5. Ultra-Low Power: requires a maximum current of 10µA (micro-ampere) when still, and 6mA when actuated.
6. High resolution: provides a sensitivity resolution up to 4096 touching levels.
7. Low Thresholds: allow for light touches and subtle movements due to the low signal thresholds available.
8. Easy integration: easy and quick to integrate, this sensor provides a plug-and-play solution for adding capacitance sensing to your projects.
9. Multiple On-chip Peripherals: this sensor includes an 8-bit timer counter, 10-bit A/D converter, and a temperature sensor.
10. Through-Hole with pogo-pin sockets: the sensor has through-hole pins and integrated sockets with spring-loaded pogo-pin contact technology for secure long-term connections.
11. Operating Voltage: the sensor is designed to operate from a 3.3V power supply.
12. Size: measures 40 mm x 40 mm in size.
