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 humidity sensor offers an extremely fast response time and therefore supports performance requirements for emerging applications such as context awareness, and high accuracy over a wide temperature range.[^2]
**4-pin variant**
The BME280 sensor board interface uses 4 pins and is 13mm by 10.5mm in size. The four pins are `VIN` `GND` `SCL` and `SDA`. The measured values are sent via I2C protocol.
