ACROBOTIC Temperature, Humidity, Barometric Pressure and Altitude Sensor Breakout Board (BME280)


Regular price $9.99

The BME280 (datasheet) is a low-power sensor that detects with high linearity and accuracy temperature, humidity, and barometric pressure. It includes both SPI and I2C interfaces for reading the measured values using our preferred microcontrollers (e.g., Arduino, ESP8266) and single-board computers (e.g., Raspberry Pi).

Because the sensor comes as a Surface-Mount Device (SMD), our Breakout Board gives easy access to all of its pins. In addition, the board includes the necessary resistors (as recommended by the sensor's manufacturer) both for the load and the sensing electrical circuits.

This high-precision sensor can measure humidity with ±3% accuracy, barometric pressure with ±1 hPa absolute accuracy, and temperature with ±1.0°C accuracy. Because of the accuracy in pressure, the sensor can be used to estimate altitude within ±1 meter!

This breakout board makes it easy to connect this sensor to your microcontroller board or single-board computer! The four pins correspond to power (VCC, GND) and I2C communication (SDA and SCL). We've included in our design pull-up resistors on the I2C lines as customary.

As with all of our Breakout Boards the pin headers are included, but they're not soldered in to allow for different use cases!
