Product Introduction
- BME280
The BME280 sensor is a small-sized, low-power digital multi-sensor that can measure the indoor environmental temperature and atmospheric pressure. It is backward compatible with the BMP280, and the control of the pressure and temperature registers as well as the data reading operation mode are the same. . The humidity sensor has a fast wake-up and response time, high accuracy and a wide temperature operating range. The air pressure sensor is a piezoresistive low-noise, high-precision, high-resolution absolute atmospheric pressure sensing element. The temperature sensing element has low-noise and high-resolution characteristics. The temperature value can perform temperature compensation and self-correction for humidity and atmospheric pressure. The humidity sensor and air pressure sensor can be independently enabled/disabled. By configuring the sampling rate register, the sampling rate of the sensitive element can be set. It is highly suitable for mobile devices with limited space, such as smartphones, tablets, smartwatches and wearable devices, weather forecasts, vertical speed indicators, flight control equipment, indoor and outdoor navigation, and smart home devices.
