8/17/2023 0 Comments Arduino nano footprint multisimIt is the successor to sensors such as the BMP180, BMP085 and BMP183. Hardware Overview BME280 ICĪt the core of the module is the next-generation digital temperature, humidity, and pressure sensor from Bosch – BME280. So, to get an accurate absolute altitude measurement, the SEA_LEVEL_PRESSURE constant is provided in the example code below, which you should update with the current sea level pressure at your location. Esas características técnicas son: Es una placa microcontroladora pequeña, flexible y de fácil uso. However, if you’re trying to measure absolute altitude, things become a bit more complicated because the BME280 needs to know the current sea level pressure. La placa Arduino Nano tiene unas características técnicas que deberías conocer antes de comenzar con ella, además de para evaluar si es lo que necesitas para tu proyecto o no cumple con tus expectativas. For example, if you know the altitude of an object sitting on a table and you move it to the floor, the BME280 will show a 2 foot decrease in height. Because the BME280 is very good at measuring pressure, it can calculate relative altitude accurately. Note that the BME280 cannot directly measure altitude but can estimate it using pressure readings. The term “absolute altitude” refers to the height above sea level (MSL), whereas “relative altitude” refers to the height above ground level (AGL). The BME280 can measure pressure with such precision (low altitude noise of 0.25m) that it can also be used as an altimeter with an accuracy of ☑ meter.īefore proceeding, it is important to understand the distinction between Absolute and Relative Altitude.
