Post by Christian_Bylund » 11 Dec 2019 18:54

If you are experiencing problems please follow these steps:
1. Check connections - See https://www.youtube.com/watch?v=w3iuqttBrPI
2. Are you using a genuine Arduino Uno?
3. Are you using a genuine Bosch LSU 4.9 sensor?
4. Are you powering the Arduino by an unstable 5V? - See https://www.youtube.com/watch?v=YBFQFQDi_Lo
5. Have you updated the Arduino Uno WiFi firmware to the latest version?
