Hi,

We are currently using the SHT40A-AW1B-R2 humidity sensor with the Jetson Orin Nano. However, we are unable to detect the sensor on the Jetson Orin Nano through the I²C interface.

To verify the hardware, we tested the same sensor with another MCU, and it was detected and communicated successfully.

Could you please help us understand why the sensor is not being detected on the Jetson Orin Nano?

hello shubham.singh21,

may I know which I2C you’re used?
if that’s Jetson Orin Nano developer kit, please refer to 40-pin Expansion Header, it’s actually using I2C1.
you may also check you’ve providing power-supply (3.3V) to your device correctly.
