Qwiic Atmospheric Sensor Breakout (SEN-15440) SparkFun Qwiic Atmospheric Sensor Breakout (SEN-15440) is based on the Bosch Sensortec BME280 Integrated Environmental Sensor. The onboard BME280 Sensor measures atmospheric pressure from 30kPa to 110kPa and relative humidity and temperature. The breakout provides a 3.3V SPI interface, a 5V tolerant I2C interface (with pull-up resistors to 3.3V), and can be configured to take measurements with less than 1mA of current draw. This SparkFun breakout can easily be connected, without soldering, to any Qwiic-based project. The pins of the BME28 are also individually broken out for other applications.
