Pressure and Altitude Sensor BMP280 I2C/SPI Module

BMP280 unit for atmospheric pressure and altitude sensor I2C / SPI is the cheapest and most affordable atmospheric sensor device for measuring atmospheric pressure and temperature readings without taking up much space. Basically, anything you need to know about weather conditions can be detected from this small breakthrough. The BMP280 Breakout is designed for use in indoor/outdoor navigation, weather forecasting, home automation, and even personal health and wellness monitoring. This unit uses an environmental sensor manufactured by Bosch with temperature, which is the atmospheric pressure sensor that is the next generation of the famous BMP085 / BMP180 / BMP183 sensors. This sensor is great for all kinds of weather sensing and can be used in both I2C and SPI; this precise Bosch sensor is the best low-cost accurate sensing solution for measuring atmospheric pressure with an absolute accuracy of ± 1 hPa and temperature accuracy of ± 1.0°C. Since pressure changes with altitude and pressure measurements are very good; it can also be used as an altitude meter with an accuracy of ± 1 meter. The BMP280 is the next generation of sensors and an upgrade to BMP085 / BMP180 / BMP183 – with low altitude noise of 0.25 m and the same fast conversion time. It has the same specifications but can use either I2C or SPI. For easy wiring, go with I2C. If you want to connect a set of sensors without worrying about I2C address conflicts, go with SPI. Specifications and features: Get more accurate temperature, atmospheric pressure values, and approximate altitude data. Improve navigation via GPS (for example, improve time to first fix, dead reckoning, and slope detection). Indoor navigation (floor detection, elevator detection). Outdoor navigation and recreational and sports applications. Healthcare applications (such as respiration measurement). Vertical speed indicator (such as climb/descent speed). Libraries and tutorials available for Arduino and other microcontrollers. Operating voltage: 1.71V to 3.6V – usually powered from 3.3V. Operating temperature: -40 to +85°C (full accuracy between 0 and +65°C). Peak current: 1.12mA. Operating pressure: 300 hPa to 1100 hPa. Accuracy ranges from 700 to 900 hPa and 25 to 40°C: ± 0.12 hPa and ± 1.0 m.
