Feature

●♥ BMP280 is an absolute barometric pressure sensor designed for mobile applications. Its small size and low power consumption of 2.7 µA @1Hz allow implementation in battery-operated devices such as cell phones, GPS modules or watches. As the successor to the widely adopted BMP180, the BMP280 offers high performance in all applications requiring accurate pressure measurement. The BMP280 operates with lower noise and supports new filter modes and SPI interface in 63% less space than the BMP180.
●♥ BMP280 sensor proprietary APSM (Advanced Porous Silicon Membrane) MEMS manufacturing process is fully CMOS compatible and allows a hermetic sealing of the cavity in an all-silicon process. The BMP280 is based on a proven Piezo-resistive pressure sensor technology featuring high EMC robustness, high accuracy and linearity, and long-term stability.
●♥ Emerging applications of indoor navigation, health care as well as GPS refinement require high relative accuracy and a low TCO at the same time. BMP280 is perfectly suitable for applications like floor detection since sensors feature excellent relative accuracy is ±0.12 hPa, which is equivalent to a ±1 m difference in altitude. The very low offset temperature coefficient (TCO) of 1.5 Pa/K translates to a temperature drift of only 12.6 cm/K.
●♥ Product parameters:①Size: 15.4mm(L)*11.6mm(W)*2.4mm(H)②Digital interface type: IIC (slave mode 3.4MHz) or SPI (3-wire or 4-wire slave mode 10MHz)③Air pressure measurement range: 300 ~ 1100hPa (hectopascal)④Air pressure measurement error: ±1hPa Resolution: 0.16Pa⑤Temperature measurement range: 0℃~65℃⑥Temperature measurement error: within ±0.5°C ±1°C Resolution: 0.01°C⑦Working voltage: 3.3V⑧With M3 fixing screw holes, easy to install and fix
●♥ BMP280 TARGET APPLICATIONS:①Enhancement of GPS navigation (e.g. time-to-first-fix improvement, dead-reckoning, slope detection)② Indoor navigation (floor detection, elevator detection)③ Outdoor navigation, leisure, and sports applications④ Weather forecast⑤ Vertical velocity indication (e.g. rise/sink speed)


Description

♥ BME280 is a small package low power digital composite sensor based on APSM process, it can measure ambient temperature and atmospheric pressure. The air pressure sensing element is a low-noise, high-precision, high-resolution absolute atmospheric pressure piezoelectric sensing element; the temperature sensing element has the characteristics of low noise and high resolution, and the temperature value can perform temperature compensation and self-correction on the air pressure. By configuring the sampling rate register, the sampling rate of the sensitive element can be set. Ideal for mobile devices with limited space, such as smartphones, tablets, smart watches and wearables, weather forecasts, vertical speed indications, flight control devices, indoor and outdoor navigation, smart home devices.
