SEN0500 environmental sensor with 3.3V Pro Mini.
brooksdr 2022-02-10 04:55:52 579 Views4 Replies Can you provide me with Arduino code for using the SEN0500 with a 3.3V Pro Mini and I2C communications? I understand that a switch om the SEN0500 must be set to I2C.
Hi! Each product has an associated wiki. It is recommended that you can refer to the study.
Tonny12138 The code is missing from the wiki for this sensor. I was able to find the library file which I downloaded from here: https://github.com/DFRobot/DFRobot_EnvironmentalSensor.
When I try to upload the code to my Arduino Nano Every from the example included with the library, readData, I get the following error message:
Arduino: 1.8.19 (Windows 10), Board: "Arduino Nano Every, ATMEGA328"

This report would have more information with"Show verbose output during compilation"option enabled in File -> Preferences.
I solved this issue myself, with more research. I had downloaded the library from github and installed it manually. I was using the 1.00 version of the library. When I updated it using the Arduino IDE Library Manager to 1.01, it worked.
