Are you looking for the best temperature and humidity sensor for arduino? If so, this video is for you.

Video sponsored by https://www.pcbgogo.com?code=y offering low cost with high-quality PCB prototype and PCB assembly service.

I tested the most popular sensors available in the search for the best and I also provide example sketches for arduino to serve as a tutorial since I wrote a lot of comments explaining the code.

Sensors considered:
- DHT11
- DHT12
- DHT22/AM2302
- AM2320
- AM2322
- HDC1080
- BME280
- LM35DZ
- SI7021/SHT21/HTU21
- HTU21D
- SHT31

Buy my top sensor:
- Buy HDC1080 amzn.to/2Thc7tv

- Buy Arduino nano: amzn.to/3iru0op
- Buy OLED 0.96" I2C: amzn.to/2UNDCLO

- Buy 75% humidity calibration kit: amzn.to/2LAnUAO
- Buy 32% humidity calibration kit: amzn.to/352Ny9d

Recommended Tools:
