The DK701 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. DK701 has a stronger anti-jamming and better consistency. The chip can work in low-power environment, when the power supply is 5v, the working current of 70ua, standby current of 5ua the following, but also for battery applications.

The DK701 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
Dielectric to sense capacitance changes. So that the sensor module can be very good with water and dust isolation. DK701 has a stronger anti-interference
And better consistency. The chip can work in low-power environment, when the power supply is 5v, the working current of 70ua, to be
The electromechanical current is below 5ua and also for battery applications.
