@bibhutibikramaditya Exactly what output are you getting? You’re not asking for data in your script, so you should only be getting a response like “00013” not any data values.
Suggestions:
- Confirm that the data pin of the Hydros 21 sensor is plugged into the correct pin (2)
- Confirm the sensor has power
- Confirm that you’re serial port…
