The DK708 touch sensor can use the average capacitance value as a reference to detect the capacitance change at the sensing point. It can be through any non-conductive medium to induce capacitance changes. So that the sensor module can be very good with water and dust isolation. DK708 has a stronger anti-jamming and better consistency. The chip can work in low-power environment, when the power supply for the 5v, the working current of 220ua, standby current of 10ua the following, but also for battery applications.

DK708 8-channel capacitive touch sensor with self-tuning function The DK708 touch sensor can use the average capacitance value as a reference to detect the capacitance change at the sensing point. It can pass any non-lead
