barometric pressure, which is the next generation upgrade to the BMP085 / BMP180 / BMP183 models. This sensor is great for all kinds of weather conditions and can even be used in both I2C and SPI! This precision sensor from Bosch is the best low-cost precision detection solution for measuring barometric pressure with an absolute accuracy of ± 1 hPa and a temperature with an accuracy of ± 1.0 ° C. Because the pressure changes with altitude, and the pressure measurements are so good that you can also use it as an altimeter with an accuracy of ± 1 meter Functionality: Model: GY-BMP280-3.3 Chip: BMP280 Power supply: 3V Communication method: communication protocol standard IIC / SPI Air pressure range: 300-1100hPa Pin pitch: 2.54mm Module size: 11.5mm * 15mm Typical application: Improvement of GPS navigation (eg Improvement of the delay until the first mark, automatic calculation, slope detection) Inland navigation (floor detection, elevator detection) Outdoor navigation, leisure and sports Weather forecast Application of healthcare (for example e, sirometry) Indication of vertical speed (for example, risk / speed of fall)
