Good sensor, careful with wiring
Works well once connected properly. The pinout diagram could be clearer. Data is stable after warm-up.

Needs Calibration
Out of the box readings were a bit high. Had to run calibration cycle. Works better now.

Q: Is this compatible with Arduino?
A: Yes, it uses UART communication which works with Arduino Uno and Mega.
Q: Can it be used outdoors?
A: It is not waterproof. You need an enclosure for outdoor deployment.
Q: What is the data output format?
A: It outputs data packets via UART at 9600 baud rate.
Q: How long does warm-up take?
A: We recommend a 30-second warm-up period for stable readings.
