OLED - tobyportugal - 08-10-2021

Hello,

A question that may seem silly to you.
On an indoor AQM III with an OLED: the display supports PM2.5/10 and AQI. Is it possible to display CO (SCD30)?
Thank you.

Hello Toby,

When the CO2 sensor is installed and enabled in the software, the CO2 readings will be show on the OLED display.

Code:
// --------------------------------------------------------------------------------------

// Define type of CO2 sensor

// --------------------------------------------------------------------------------------

#define CO2_SENSORTYPE 1 // 0= Not instaled, 1= Sensirion SDC30, 2= MH-Z19

// --------------------------------------------------------------------------------------

// Settings for the Sensirion SCD30 - CO2 Sensor

// --------------------------------------------------------------------------------------

// The sensirion SDC30 compensate the CO2 readings by using one of two methods: Atmospheric Pressure or a fixed Altitude value.

// Define bellow which one you want to use.

#define SDC30_ELEVATION_CALIBRATION_METHOD 1 // 0= Elevation defined above, 1= Atmospheric Pressure from BME280 sensor (overrides ELEVATION)

// If the SDC30 is intalled, system will use its high quality built-in Temperature / Humidity sensor. BME280 will be used only for Atmospheric Pressure.

// Optionally we can set a temperature offset up to 5.0 °C, stored in non-volatile memory of SCD30

const float SCD30_TemperatureOffset = 2.0; // Format: float

Rgs.
