Touch Keypad Module 4×1 OS25B10 HMC5883L 3-axis MagnetometerIntroduction : This Capacitive Touch Module uses the touch sensing IC TTP224 to add capacitive touch to your project . Just power with 2. 4 to 5. 5VDC and touch the pad to activate the sensor. These touch switches interface easily to any project with or without a microcontroller. When a capacitive load (such as a human hand) is in close proximity to the sense pad, the sensor detects the change in capacitance and activates the switch. Custom sense pads
