Description

Product information "SparkFun MicroMod Environmental Function Board"

The SparkFun MicroMod Environmental Function Board adds additional sensor options to the MicroMod Processor Boards. This function board contains three sensors for monitoring air quality (SGP40), humidity, temperature (SHTC3) andCO2 concentration(STC31) in your indoor environment. To make it even easier to use, all communication takes place via the MicroMod's I2C bus!

  • The SGP40 measures the quality of the air in your room or house. The SGP40 utilises a metal oxide (MOx) sensor with a temperature controlled micro heating plate and provides a humidity compensated, volatile organic compound (VOC) based indoor air quality signal. Both the sensor element and the VOC algorithm are characterised by unrivalled robustness to contaminating gases found 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 utilises 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 the SHTC1 sensor and offers greater accuracy (±2% RH, ±0.2°C) than its predecessor, allowing for greater flexibility.

  • The STC31 measuresCO2 concentrations based on thermal conductivity and has twoCO2 measurement ranges: 0 to 25 vol% and 0 to 100 vol%. The repeatability of the measurement is 0.2 vol%, with a stability of 0.025 vol% / °C. The measurement accuracy depends on the measuring range: 0.5 vol% + 3% measured value; 1 vol% + 3% measured value. Utilising the measurements of the SHTC3, the STC31 is able to provide humidity compensated measurements together with improved temperature compensation. The STC31 can also compensate for atmospheric pressure - which is handy if you're in the mountains like us!
The outstanding performance of these three sensors is based on Sensirion's patented CMOSens®-Technology from Sensirion, which combines the sensor element, signal processing and digital calibration on a small CMOS chip. The proven CMOS technology is ideally suited for high-quality mass production and is the ideal choice for demanding and cost-sensitive OEM applications.

Thanks to our practical M.2 MicroMod connector, no soldering is required to connect it to your system. Simply align the bevelled connector of your processor and function board with the corresponding key of the M.2 connector and then secure them to the motherboard with screws. The MicroMod Environmental Function Board can then be read out via the I2C port. The board is equipped with the AP2112 3.3 V voltage regulator, I2C pull-up resistors, a power LED, a jumper for deactivating the LED and jumpers for alternative STC31 addresses.

Note: The I2C addresses reserved for each sensor are 0x59 (SGP40), 0x70 (SHTC3), 0x29 (STC31). A multiplexer/mux is required to communicate with multiple SHTC3 sensors on a single bus. The SHTC3 uses the same address as the Qwiic Mux (0x70). For advanced users using multiple SHTC3s with the Qwiic Mux, you will need to adjust the default address of the Qwiic Mux.
