This is a frugal CO₂ sensor so most of the parts can be interchanged with similar ones. A detailed Bill of Materials with the exact components used in this version of the sensor is provided as ...

先週に引き続き電子工作について書きます。 前回は、Grove Beginner Kit For ArduinoでCO2濃度測定機を作成しました。シリアルモニタに測定値を出力し、CO2が一致値を超えるとブザーとLEDをONにするところまでやりました。 いちおう最低限の機能は実装できましたが ...

Code to quickly recalibrate a SCD-30 sensor using Arduino. If sensor is not returning values around 400-450ppm when outside, use this code to reset it. Also disables automatic self-calibration because ...

In this project my aim is to develope CO2 level supevisory tool with STM32WB, SPG40 CO2 sensor and widespread Tuya smarthome framework and smartphone app. Tuya compatible zigbee gateways are made by ...
