API

SHT20

pm25_sht20.get_num_above_0_3()

• Retrieves the number of particles with a diameter greater than 0.3 (2.5/10) micrometers in the air, measured in particles per 0.1 liters of air. Returns an integer value.

pm25_sht20.get_pm1_0_factory()

• Retrieves the PM1.0 (PM2.5, PM10) concentration value from the PM2.5 sensor (SHT20).
  • PM: Represents particulate matter concentration, usually measured in micrograms per cubic meter (µg/m³).
  • ATE: This option typically represents Air Quality Index (AQI) or another specific measurement standard, though the exact meaning may depend on the device or application definition.

pm25_sht20.get_sht20_humidity()

• Retrieves the relative humidity value, expressed as a percentage of relative humidity (%RH). Returns a floating-point number.

pm25_sht20.get_sht20_temperature()

• Retrieves the temperature value, measured in degrees Celsius (°C). Returns a floating-point number.

SHT30

pm25_sht30.get_sht30_humidity()

• Retrieves the relative humidity value, expressed as a percentage of relative humidity (%RH). Returns a floating-point number.

pm25_sht30.get_num_above_0_3()

• Retrieves the number of particles with a diameter greater than 0.3 (2.5/10) micrometers in the air, measured in particles per 0.1 liters of air. Returns an integer value.

pm25_sht30.get_pm1_0_factory()

• Retrieves the PM1.0 (PM2.5, PM10) concentration value from the PM2.5 sensor (SHT30).
  • PM: Represents particulate matter concentration, usually measured in micrograms per cubic meter (µg/m³).
  • ATE: This option typically represents Air Quality Index (AQI) or another specific measurement standard, though the exact meaning may depend on the device or application definition.

pm25_sht30.get_sht30_temperature()

• Retrieves the temperature value, measured in degrees Celsius (°C). Returns a floating-point number.
