Package Included:
1 X GY-BMP280-3.3 Pressure Sensor
1 X GY-BMP280-3.3 Pressure Sensor
BME280 is a small package low power digital digital composite sensor, it can measure ambient temperature and humidity and atmospheric pressure. It is backward compatible with the BMP280, and the barometric temperature register control and data readout operation are the same. The humidity sensor has fast wake up and response time, high precision and wide temperature operating range; The pressure sensing element is a piezoresistive low noise, high precision and high resolution absolute atmospheric pressure sensing element. The temperature sensing element has the characteristics of low noise and high resolution, and the temperature value can be self-corrected by temperature compensation for humidity and air pressure. Humidity sensing elements and pressure sensing elements can be independently enabled/disabled. By configuring the sample rate register, you can set the sample rate of the sensor. Ideal for mobile devices with limited space, such as smart phones, tablets, smartwatches and wearables, weather forecasts, vertical speed indicators, flight control devices, indoor and outdoor navigation, smart home devices.
