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

- Calibrate SCD40
- Refer to the CO2 calibration guide. Place your sensor outside and click this button to calibrate the CO2 levels
Sensors
BME280 HumidityAmmoniaHumidity readingMeasurement fromtheMiCS-4514BME280.gasThis is affected by the configuration variable "BME280 Humidity Offset". Changing the offset allows you to dial in the humidity to a known value.
BME280 Humidity Calibrated- Removed In v23.11.01.1sensorWe calibrated the BME280 against a lab-rated reference sensor. We set the linear offset values in the YAML and this variable is the output.

BME280 TemperatureTemperature reading from BME280. This is affected by the configuration variable "BME280 Temperature Offset". Changing the offset allows you to dial in the temperature to a known value.

- 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

Radar Detection DistanceThe last detected distance by the radar. This will stay at the last known value so sometimes can be misleading
Radar Move EnergyThe amount of movement measured by the LD2410B. Faster movements have higher %
Radar Moving TargetDoes the radar have a moving target it is tracking
Radar Still DistanceThe last measured distance of a still target. It will hold the last value so sometimes can be misleading
Radar Still EnergyThe energy of the current still target
Radar Still TargetDoes the radar have a still target
Radar TargetDoes the radar have a still or moving target. Good for triggering automation.
Radar Zone 1 OccupancyThis is a configurable zone. Think of zones like distancesMeasurement fromtheMiCS-4514radar unit. Zone 1 might be from 0 inch to 12 inches from the sensor. This is telling you if there is someone in that zone. The zones can be defined in the configuration section with “Radar End Zone 1”
Radar Zone 2 OccupancySame as zone 1 but just the second zone from thegas sensor
Radar Zone 3 OccupancyHydrogenSameMeasurementasfromzoneMiCS-45141gas& 2 but with the third zone.sensor
SCD40 Humidity- Removed In v23.11.01.1MethaneThis is the humidity readingMeasurement fromtheMiCS-4514SCD40.gasWill be unknown if you do not have the CO2 modulesensor
SCD40NitrogenTemperature- Removed In v23.11.01.1DioxideThis is the temperature readingMeasurement fromtheMiCS-4514SCD40.gasWill be unknown if you do not have the CO2 modulesensor
- PM < 10 uM
- Measurement of particulates smaller than 10 uM
- PM < 1 uM
- Measurement of particulates smaller than 1 uM
- PM < 2.5 uM
- Measurement of particulates smaller than 2.5 uM
- PM < 4 uM
- Measurement of particulates smaller than 4
Configuration
- BME280 Humidity Offset
- Allows you to adjust the reading of the “BME280 Humidity” sensor to match a known value
- BME280 Temperature Offset
- Allows you to adjust the reading of the “BME280 Temperature” sensor to match a known value
- CO2 Calibration Number
- See calibrating CO2: Here
- ESP Reboot
- Performs a restart of the sensor
- Factory Reset Radar
- Sets the radar's move thresholds back to their original values from the manufacturer
- g0-g8 Move & Still Threshold
- Please refer to the radar tuning guide: Here
- Radar Control Bluetooth
- This allows you to turn on the LD2410's Bluetooth. This allows you to connect to the HLK Radar phone app if you wanted to upload new firmware to the radar unit (Not the MSR-1 in general, just the radar chip)
- Radar End Zone 1
- This defines “Zone 1” of the radar. It is a distance from the sensor that specifies what “Zone 1” is. It connects to the “Radar Zone 1 Occupancy” sensor. So if this number is set to “10” that means from 0 to 10 centimeters from the sensor is zone 1.
- Radar End Zone 2
- Same as Zone 1. This defines from the end of Zone 1, how far does Zone 2 extend
- Radar End Zone 3
- Like Zone 2, this defines how far from the end of Zone 2 does zone 3 end.
- Radar Max Move Distance
- Maximum distance for the LD2410 movement detection
- Radar Max Still Distance
- The max distance for the LD2410 still target detection
- Radar Timeout
- The time in seconds that the radar's presence will stay high after the target is lost.
SCD40 Humidity Offset- Removed In v23.11.01.1Allows you to adjust the reading of the “SCD40 Humidity” sensor to match a known value.
SCD40 Temperature Offset- Removed In v23.11.01.1Allows you to adjust the reading of the “SCD40 Temperature” sensor to match a known value
