mmWave C4001 24GHz Human Presence Detection Sensor (12 Meters, I2C & UART)
Sergio.Or 2025-05-14 01:52:05 426 Views3 Replies I have the C4001 Sensor and i want to minimize the code size since i'm using a low memory uc. Is there any documentation about i2c protocol, registers and responses?
Best Regards

I dont want to use demo libraries, is there any documentation about registers? procedure to configure? etc?

I believe these sensors are serial only. After examining the code (I just purchased one myself) I would say that you may need to consider a more capable microcontroller if the code doesn't fit.

EDIT: Apologies, yes, they are I2C as well, however, my comment about needing a more capable uC stands :)
