Sensor Definitions

Once added to Home Assistant you can configure different settings for your sensor. Below is what each setting does.

Controls

• RGB Light
  • 3 RGB Neopixels. Click on the light bulb to change the color. Click on the toggle to turn on or off
• Calibrate SCD40
  
  • Refer to the CO2 calibration guide. Place your sensor outside and click this button to calibrate the CO2 levels

Sensors

• Ammonia
  • Measurement from MiCS-4514 gas sensor
• Carbon Monoxide
  • Measurement from MiCS-4514 gas sensor
• CO2
  • True CO2 reading from the SCD40. This will be Unknown if you do not have the CO2 module. This can be calibrated following this guide but does come precalibrated: Here
    
• DPS310 Pressure
  • Atmospheric pressure, used to better calibrate the SCD40 CO2 module
• DPS310 Temperature
  • A worse measurement of temperature. This is more susceptible to internal heat buildup. Please use the SEN55 temperature
• ESP Temperature
  • This is the temperature of the internal ESP chip. Think of it like your measured CPU temp on your PC
• Ethanol
  • Measurement from MiCS-4514 gas sensor
• Hydrogen
  • Measurement from MiCS-4514 gas sensor
• Methane
  • Measurement from MiCS-4514 gas sensor
• Nitrogen Dioxide
  • Measurement from MiCS-4514 gas sensor
• PM < 10 µM
  • Measurement of particulates smaller than 10 µM
• PM < 1 µM
  • Measurement of particulates smaller than 1 µM
• PM < 2.5 µM
  • Measurement of particulates smaller than 2.5 µM
• PM < 4 µM
  • Measurement of particulates smaller than 4 µM
• SEN55 Humidity
  • Humidity measurement from SEN55, will be most accurate
• SEN55 NOX
  • Measurement of nitrogen oxides from the SEN55
• SEN55 Temperature
  • Measurement of temperature from the SEN55, will be most accurate
• SEN55 VOC
  • VOC index from the SEN55
• VOC Quality
  • This uses the VOC index and a scale to output an easier to use variable
    • 0-79: Improved
    • 80-119: Normal
    • 120-199: Abnormal
    • 200-299: Very abnormal
    • 300+: Extremely abnormal
• PM 0.3 To 1 µm
  
  • Disabled by default but can be enabled in HA. Shows particulate count that are from 0.3 to 1.0 µm
• PM 1 To 2.5 µm
  
  • Disabled by default but can be enabled in HA. Shows particulate count that are from 1 to 2.5 µm
• PM 2.5 To 4 µm
  
  • Disabled by default but can be enabled in HA. Shows particulate count that are from 2.5 to 4.0 µm
• PM 4 To 10 µm
  
  • Disabled by default but can be enabled in HA. Shows particulate count that are from 4.0 to 10.0 µm

Configuration

• ESP Reboot
  • Performs a restart of the sensor
• SEN55 Temperature Offset
  • Allows you to calibrate the SEN55 temperature. Please refer to our calibration guide
• SEN55 Humidity Offset
  • Allows you to calibrate the SEN55 humidity. Please refer to our calibration guide
• Startup Light Blink
  
  
  • Controls if the led blinks after power on when trying to connect to HA
