Hi, I’ve setup HA integration of SCD30 with ESP32 D1 Mini through MQTT and the SCD30 CO2 sensor started giving really big random measurements time to time.
I left it in an empty room for a day and noticed weird peaks on HA, so decided to bring it back to the computer and see if it reproduces. And it did, this is a Serial.print() from the Arduino IDE:
19:30:20.097 -> CO2(ppm):754.70
19:30:20.097 -> Temperature:27.02
19:30:20.097 -> humidity:32.72
19:30:40.130 -> CO2(ppm):-1992407428506845157.30
19:30:40.130 -> Temperature:-14952457328909054545817980397.25
19:30:40.130 -> humidity:3344962682880.00
19:30:40.130 -> CO2(ppm):754.23
19:30:40.130 -> Temperature:27.04
19:30:40.130 -> humidity:32.70
As you can see huge values. Happened like 4 - 5 times throughout the day. Otherwise it seems the measurements are alright. I had it outside for a short time and CO2 was around 400 ppm. Anyone had something similar?
