Hello. I am trying to set up an Air Quality Monitoring System with an NodeEMCU v3 - esp8266, an BME280 and a Sensirion SPS30.
I flashed the firmware 0.3.2 with the airRohr-Flashing Tool onto the Node and connectet it with my WiFi. After that i connected the BME280 like it is shown in the instructions from the sensor.community webpage.
I also connected the Sensirion SPS30 with the help of a JST ZH connector from “berrybase” like the way the SDS011 is connected, but i didn’t connect the Pin 4 “SEL” from the SPS30 sensor. My Powersupply is the official Rasperry Pi Poweradapter.
After plugging in the system i can see the BME280 is working fine, but i don’t get any data from the SPS30. In the errorbox in the software it shows:
I didn’t find any solution in the forum. Could someone help me with my problem? Maybe I connected something wrong? Unfortunately I don’t know what to do with the error “0”.
