We need to put the processor in sleep mode (to conserve battery power) and wake-up the processor when the user touches the Cap Sensor pad. Can you Cap Sensor in nrf52 be used for this feature? Will it be power efficient? -siddarth

Hi, I am using the capacitive sensing driver example given in the SDK(version 12.3) and it works fine. I want to extend the code to ensure that the SoC goes to sleep for 60 seconds and then wakes up for just one or two seconds to take measurements…

Currently, we are trying to have the nRF51 chip working with a type of capacitive pressure sensor. We did quite a lot of work on searching proper circuits of reading the capacitance of the sensor, including capacitance voltage divider, charging time method…
