Hi,

Is it possible to controll the lights by the movements using inbuilt sensors on the QCA4020 board?

Like detecting fast or slow motion.

NOTE:- Able to detect the movement using PIR sensor. But not speed of movement.

Thank you,

We dont have the provision in our Demos to control the LED based on Speed of movement.
However, you can try to execute similar instance by connecting Pin 1 of J25 (PIR_OUT_LR) to Pin 1,3,5,7,9,11 of J16(LED).

When ever there is a movement on PIR sensor the J25 (PIR_OUT_LR) which is configured as DUAL_EDGE_TRIGGER and send will send an Interrupt signal .
If you connect the J25 Pin1to J16 pin1(WLAN_LED), based on slow or fast movement, the LED will glow constant or blink.
