This BMP280 is a cheap and small atmospheric sensor breakout for measuring barometric pressure and temperature without taking up too much space. Basically, everything you need to know about atmospheric conditions can be learned from this small eruption. The BMP280 Breakout is designed for use in indoor / outdoor navigation, weather forecasting, home automation, and even personal health and wellness monitoring.
This module uses a Bosch environmental sensor with temperature and barometric pressure sensors, which is the next generation of the popular BMP085 / BMP180 / BMP183 sensors. This sensor is ideal for all types of weather sensors and can also be used with both I2C and SPI. Bosch's precision sensor is the most cost-effective precision measurement solution for measuring barometric pressure with an absolute accuracy of ± 1 hPa and temperature with an accuracy of ± 1.0 ° C. The barometric pressure changes depending on the altitude, and the barometric pressure reading is very good, so it can also be used as an altimeter with an accuracy of ± 1 meter.
The BMP280 is the next generation sensor, an upgrade of the BMP085 / BMP180 / BMP183 with the same high speed conversion time as the low altitude noise of 0.25m. The specifications are the same, but either I2C or SPI can be used. Use I2C for easy wiring. If you want to connect a large number of sensors without worrying about I2C address collisions, use SPI.
