Description:
BME280, the precision sensor is soldered onto PCB.Not only the pressure and the temperature, but this sensor can also measure humidity; Humidity sensor and pressure sensor can be independently enabled/disabled.It uses both I2C (up to 3.4MHz) and SPI (supports 3 and 4 wire SPI) interface.Current consumption 1.8 μA @ 1 Hz humidity and temperature.Supply voltage VDD main supply voltage range: 1.71 V to 3.6 V ; VDDIO interface voltage range: 1.2 V to 3.6 V2.8 μA @ 1 Hz pressure and temperature3.6 μA @ 1 Hz humidity, pressure, and temperature0.1 μA in sleep modeOperating range -40…+85 °C, 0…100 % rel. humidity, 300…1100 hPaBME280 digital pressure sensor RoHS compliant, halogen-free, MSL1Key parameters for humidity sensor1Response time 1 sAccuracy tolerance ±3 % relative humidityHysteresis ±1% relative humidityKey parameters for pressure sensorRMS Noise 0.2 Pa, Equiv. to 1.7 cmOffset temperature coefficient ±1.5 Pa/K, Equiv. to ±12.6 cm at 1 °C temperature changeMaterial: PlasticSize: approx. 20mm*12mm*3mm
