Project about Connect BMP280 Pressure Sensor Module With Arduino

[erin]

Introduction

If you want to build your own temperature monitoring system or measure the altitude of a drone, or just want to measure the atmospheric pressure in your area, then one of the best modules to use in your project is the BMP280 Pressure Sensor Module. BMP280 is an absolute pressure and temperature monitoring sensor, which is an upgraded version of BMP085, BMP180 and BMP183 sensors. Why is it called an upgraded version? It will be discussed in the following sections.

The BMP280 sensor module can be used with microcontrollers such as Arduino, PIC, AVR, etc. For this project we will use Arduino Uno and BMP280 along with LCD 16x2 display module to display temperature and pressure values. Before connecting the BMP280 with Arduino, we need to download the BMP280 Arduino library developed by Adafruit.

Thanks for sharing the project. If you want to create a PCB with casing for your BMP280-based projects in the future, you can consider this design. It broadcasts temperature and pressure updates every 4 seconds. The gateway and 3-button remote use the pressure readings to calculate the altitude.10440 Li-ion 3.7V 600mAh AAA size battery that lasts several months on a single charge. It has a 3D-printed water-resistant enclosure.
