SparkFun MicroMod Environmental Function Board (SEN-18632)

SparkFun MicroMod Environmental Function Board (SEN-18632) is designed to work with the MicroMod modular interface ecosystem. The Environmental Function Board includes three sensors to monitor air quality (SGP40), humidity and temperature (SHTC3), and CO2 concentrations (STC31). For ease of use, all communication is over the MicroMod Main Board I2C bus.

The three sensors included on the SparkFun MicroMod Environmental Function Board are based on Sensirion CMOSens® technology, which combines the sensor element, signal processing, and digital calibration on a small CMOS chip. CMOS technology is well suited for high-quality mass production and ideal for demanding and cost-sensitive OEM applications.

Utilizing the handy M.2 MicroMod connector, no soldering is required to connect the Environmental Function Board to a new or existing MicroMod application. The MicroMod Environmental Function Board can then be read via the I2C port. The SEN-18632 Board is equipped with a 3.3V voltage regulator, I2C pull-up resistors, a power LED, a jumper to disable the LED, and jumpers for alternative STC31 addresses.

MicroMod

MicroMod is a modular interface ecosystem that connects a microcontroller processor board to various carrier board peripherals. Utilizing the M.2 standard, the MicroMod standard enables the user to swap processors and function boards easily. A MicroMod Carrier Board and a Processor Board are required to use the MicroMod Environmental Function Board and are not included. These boards will need to be purchased separately.
