Description
Barometric pressure and temperature sensor module built around the Bosch BMP280. It measures pressure from 300 to 1100 hPa with ±1 hPa absolute accuracy and ±0.12 hPa relative accuracy, good enough to use as an altimeter with ±1 meter accuracy, and temperature from -40 to +85°C with ±1.0°C accuracy. I2C and SPI interface. An upgrade for the BMP180, it measures altitude and temperature.
The BMP280 is a pressure and temperature sensor only. It does not measure humidity (that is the BME280, a different sensor, sold separately). It talks over I2C (up to 3.4 MHz) or SPI (up to 10 MHz), runs on 1.8–5V, and draws just 2.7 µA at a 1 Hz sampling rate. The sensor is an 8-pin LGA metal-lid package (2.0 x 2.5 mm) on a 1.52 x 1.20 cm board.
Use it for weather stations, altitude logging, GPS navigation enhancement, indoor navigation, and any Arduino or ESP32 project that needs accurate pressure or altitude. Sold as a single module, 3.3V version. I check every order before it ships. Ships from NY, USA.
