The BME280 is as combined digital humidity, pressure and temperature sensor based on proven sensing principles. The sensor module is housed in an extremely compact metal-lid LGA package with a footprint of only 2.5 × 2.5 mm² with a height of 0.93 mm. Its small dimensions and its low power consumption allow the implementation in battery driven devices such as handsets, GPS modules or watches. The BME280 is register and performance compatible to the Bosch Sensortec BMP280 digital pressure sensor
Key Features:
- Package- 2.5 mm x 2.5 mm x 0.93 mm metal lid LGA
- Digital interface- I²C (up to 3.4 MHz) and SPI (3 and 4 wire, up to 10 MHz)
- Supply voltage
- VDD main supply voltage range: 1.71 V to 3.6 V
- VDDIO interface voltage range: 1.2 V to 3.6 V
- 2.8 µA @ 1 Hz pressure and temperature
Key parameters for humidity sensor:
- Response time: 1 s
- Accuracy tolerance: ±3 % relative humidity
- Hysteresis: ±1% relative humidity
Key parameters for pressure sensor:
- RMS Noise: 0.2 Pa, equiv. to 1.7 cm
- Offset temperature coefficient: ±1.5 Pa/K, equiv. to ±12.6 cm at 1 °C temperature change
Typical applications:
- Context awareness, e.g. skin detection, room change detection
- Health monitoring / well-being
- Warning regarding dehydration or heat stroke
- Spirometry (measurement of lung volume and air flow)
- control heating, venting, air conditioning (HVAC)
