Feature

●It is a digital coincidence sensor with small package and low power consumption, which can measure ambient temperature, humidity and atmospheric pressure.
●It is backward compatible with BMP280, and the control and data readout operation modes of the air pressure and temperature registers are the same.
●The humidity sensor has fast wake-up and response time, high precision and wide temperature operating range; the air pressure sensor is a piezoresistive low-noise high-precision high-resolution absolute atmospheric pressure sensor.
●The temperature sensing element has the characteristics of low noise and high resolution, and the temperature value can perform temperature compensation and self-calibration on humidity and air pressure. Temperature sensing element and air pressure sensing element can be enabled/disabled independently.
●With configuration adoption, it is ideal for space-constrained mobile devices such as smartphones, tablets, smart watches and wearables, indoor and outdoor navigation, smart home installations.
