BME280 Temperature & Humidity Sensor - 5V I2C

The BME280 is an environmental sensor that measures pressure, temperature, and humidity and allows for a comprehensive measurement of the environment. The BME280 sensor has been especially developed for mobile applications and wearables where size and low power consumption are key design parameters. The unit combines high linearity and high accuracy sensors and is perfectly feasible for low current consumption, long-term stability and high EMC robustness. The BME280 sensor offers an extremely fast response time and therefore supports performance requirements for emerging applications such as context awareness, and has a high accuracy over a wide temperature range.
This breakout board also features an on-board 3.3VDC LDO and level shifting circuitry, allowing easier integration into a system running on 5VDC. Both SDA and SCL pins will safely operate at the same level as the VIN pin.
