The SparkFun MicroMod Environmental Function Board includes three sensors to monitor air quality (SGP40), humidity & temperature (SHTC3), and CO2 concentrations (STC31) in your indoor environment.

The SGP40 measures the quality of the air in your room or house. The SGP40 uses a metal oxide (MOx) sensor with a temperature-controlled micro hotplate and provides a humidity-compensated volatile organic compound (VOC) based indoor air quality signal. Both the sensing element and VOC Algorithm feature unmatched robustness against contaminating gases present in real-world applications enabling unique long-term stability as well as low drift and device to device variation.

The SHTC3 is a highly accurate digital humidity and temperature sensor. The SHTC3 uses a capacitive humidity sensor with a relative humidity measurement range of 0 to 100% RH and a bandgap temperature sensor with a temperature measurement range of -40°C to 125°C. The SHTC3 builds on the success of its SHTC1 sensor with higher accuracy (±2% RH, ±0.2°C) than its predecessor, enabling greater flexibility.

The STC31 measures CO2 concentrations based on thermal conductivity and has two CO2 measurement ranges: 0 to 25 vol%; and 0 to 100 vol%. The measurement repeatability is 0.2 vol%, with a stability of 0.025 vol% / °C. The measurement accuracy depends on the measurement range: 0.5 vol% + 3% measured value; 1 vol% + 3% measured value.

Using measurements from the SHTC3, the STC31 is able to provide humidity-compensated measurements together with improved temperature compensation. The STC31 can compensate for atmospheric pressure too - which is handy if for example you’re up in the mountains!

Note: A MicroMod Processor and Main Board are not included with this MicroMod Environmental Function Board. These boards will need to be purchased separately.
