Product Description

The BME280 is a combined humidity, pressure and temperature sensor that allows for two devices per I2C port.

The humidity sensor in the BME280 provides an extremely fast response time and high overall accuracy with ±3%RH. The pressure sensor in this device is an absolute barometric pressure sensor with extremely high accuracy and resolution and low noise output. The temperature sensor has been optimized for the lowest noise and highest resolution and is used for temperature compensation of the pressure sensor and can also be used for estimation of ambient temperature. Measurements with the BME280 can be performed by the user or performed at regular intervals.

All I2C Mini Modules are designed to operate at 5VDC. This Mini Module includes onboard power regulation and PCA9306 I2C level shifting circuitry to adapt to our 5V I2C standard. Using a convenient 4-Pin plug, devices can be daisy-chained onto the I2C Bus, eliminating the need for soldering. Plug together all the pieces you need for your next automation application.

Pull-up resistors are included with all Dcubestore.com master devices. If you are wiring in your own I2C port, onboard 4.7K jumper-selectable pull-up resistors are available for convenience purposes.

All I2C Mini Modules include an I2C Cable.

IoT Compatibility:
This is a general purpose I2C device compatible with all computing platforms and IoT technologies, including Raspberry Pi, BeagleBone, Arduino, Particle, BridgeX5, and much more. All Dcubestore.com devices support a strict +5V I2C Bus standard.
