DESCRIPTION The BME280 Environmental Sensor (Temperature Humidity Barometer) provides a precise measurement of not only barometric pressure and temperature, but also the humidity i n the environment. The air pressure can be measured in a range from 300 hPa to 1100hPa with ±1.0 hPa accuracy, while the sensor works perfectly for temperatures between - 40℃ and 85℃ with an accuracy of ±1℃. As for the humidity, you can get a humidity value with an error less than 3%. Owing to its high accuracy on measuring the pressure, and the pressure changes with altitude, we can calculate the altitude with ±1 meter accuracy, which makes it a precise altimeter as well. Note: As the sensor is quite sensitive to the environmental conditions, please DO NOT touch it with your fingers. FEATURES High accuracy, absolute accuracy of ±1.0 hPa for pressure, ±1 accuracy for temperature and ±3% for humidity Can be used as an altimeter with the accuracy of ±1 meter TECHNICAL DETAILS Supply Voltage: 3.3V -5V Current Consumption: 0.4 mA Humidity Accuracy: ±3% Temperature Range: -40°C to 85°C Temperature Accuracy: ±1 Pressure Range: 300 – 1100 hPa Pressure Accuracy: ±1.0 hPa SHIPPING LIST 1x Temperature Humidity Barometer Sensor (BME280) Soldered Pins Show more
