SCD30 ESP32

Create Your Own CO2 Monitor | Sensirion

Connect the SCD30 sensor to the ESP32 DevKitC as depicted below. Please note, that your developer kit may have a different pin layout. If you're using different pins or have a different layout, you might have to adjust the code accordingly: VDD of the SCD30 to the of the ESP32; GND of the SCD30 to the GND of the ESP32

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.

esp32 does not read analogue values - ESP32 Forum

Mar 27, 2021· Re: esp32 does not read analogue values. I find that the ESP32 does, indeed, read analog values and does a nice job doing so. Using analog read, the Arduino way is not as accurate as using the ESP32 way. Remember the ESP32 is a volt device so you may, up to you, want to use a voltage divider, with 1% resistors.

Comparison of multiple SCD30 CO₂ sensor -

Dec 27, 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.
