mmWave - Human Presence Detection Sensor # SEN0395

Hi Team,

I recently purchased the #SEN0395 mmWave Human Presence Detection Sensor.

I attempted to configure the sensor to work independently, meaning I successfully set it up to function without any start command.

However, the sensor only operates when connected with Tx and Rx. Upon removing the Tx and Rx connections, GPIO-2 immediately ceases to function. According to the data sheet, GPIO-2 should be high when presence is detected, but this does not occur when the TTL interface connection is removed.

I have saved the configuration as per the data sheet. Is there any step I might be missing to make the sensor independent?

Best Regards,

Raja
