SCD30 ESP32

Lo Furòl - Capteur CO2 Neko

23/05/2021· Remarque : Mon module ESP32 n'ayant pas de broche 21, je l'ai remplacée par la broche 23 dans le programme .ino. À TESTER sur platine d'essais. Montage à tester : Montage sur plaque d'essais pour tester. Une fois que tout est prêt (module ESP32 flashé), on teste sur plaque d'essais. Dans l'image ci-contre, on devine la diode verte allumée.

Simple LED Bar Graph CO2 Sensor : 4 Steps (with Pictures ...

The SCD30 sensor communicates with the ESP32 MCU via the I2C interface. Each segment of the LED bar graph is connected to an IO pin of the MCU with a series resistor that limits the current and therefore brightness of the LEDs. I originally planned to use 150 Ohm for all segments but then increased the value because the segments were very bright. In addition, I used different resistors for the ...

Comparison of multiple SCD30 CO₂ sensor -

27/12/2020· The software on the ESP32 initialises all sensors to work with a measurement interval of 15 s, a temperature offset of 1 °C, and activated automatic self-calibration. Every 15 s it queries the current pressure from the BMP280 and updates the pressure values in the SCD30 sensors if ambient pressure has changed. It also prints out all measurement values over a virtual serial port on USB.
