Sparkfun smôl Environmental Peripheral Board

The smôl Environmental Peripheral Board is a compact and power-efficient addition to the smôl ecosystem. This board features three low-power sensors: the BME280 for pressure, humidity, and temperature measurements; the SGP40 for air quality sensing; and the VEML7700 for ambient light sensing. These sensors make the smôl Environmental Peripheral Board a versatile tool for various applications.

The smôl Environmental Peripheral Board is part of the smôl ecosystem, a family of miniature processor boards, peripheral boards, power boards, and accessories. These boards are designed to be physically small and to draw minimal current, making them ideal for applications such as wildlife tracking or long-term monitoring. The smôl boards are designed to stack on top of each other, using 16-way 0.5mm-pitch Flexible Printed Circuits (FPCs) for interconnectivity. If you're seeking a compact solution for your next project, the smôl Environmental Peripheral Board is a great choice.

The smôl Environmental Peripheral Board is equipped with the BME280 sensor for measuring pressure, humidity, and temperature. This sensor has a typical current consumption of 340µA for humidity measurement, 714µA for pressure measurement, and 350µA for temperature measurement. It can operate within a temperature range of -40°C to 85°C, a humidity range of 0-100% RH, and a pressure range of 300-1100 hPa.

The board also includes the SGP40 Air Quality sensor, which has a typical current consumption of 2.6mA during continuous operation and 34µA when idle. It outputs a digital raw value (SRAW) ranging from 0 - 65535 ticks and a digital processed value (VOC Index) ranging from 0 - 500 VOC Index points.

The VEML7700 Ambient Light sensor on the board consumes a typical current of 45µA during operation and 0.5µA during shutdown. It can measure ambient light within a range of 0.01 lux to 167000 lux with a resolution of 0.005 lx/ct.

The smôl Environmental Peripheral Board measures 40.6mm in length, 10.7mm in width, and has a PCB thickness of 0.8mm. It uses I2C interface for communication with the BME280, SGP40, and VEML7700 sensors.

The smôl Environmental Peripheral Board comes with comprehensive documentation, including schematics, Eagle files, and hardware repositories for the board and each of its sensors. This ensures you have all the information you need to fully utilize this compact and power-efficient board.
