Upload the code to your Arduino Board. Open the Serial Monitor at a baud rate of 9600. You should see the readings displayed on the Serial Monitor. The BME280 provides an easy and inexpensive way to get pressure, temperature and humidity readings.

The BME280 sensor uses I2C or SPI communication protocol to exchange data with a microcontroller. We’re using the module illustrated in the figure below. This sensor communicates using I2C communication protocol, so the wiring is very simple. You connect the BME280 sensor to the Arduino Uno I2C pins as shown in the table below:

The Bosch BME280 is a three-in-one environment sensor that can sense temperature, humidity, and pressure. This makes it ideal for use in projects such as mini weather stations. In this guide, we will use the Arduino UNO development board and program it using Arduino IDE version 2.

You might also like reading other BME280 guides: The BME280 sensor module reads barometric pressure, temperature, and humidity. Because pressure changes with altitude, you can also estimate altitude. There are several versions of this sensor module. The BME280 sensor uses I2C or SPI communication protocol to exchange data with a microcontroller.
