Wiring a digital temperature and humidity sensor to the I2C bus


Now, we will use a multifunctional digital sensor that will provide us with temperature and relative humidity information. We will use a breakout board that uses the I2C bus to allow the Intel Galileo Gen 2 board to communicate with the sensor. The sensor is useful when we don't need to measure temperature and humidity in extreme conditions. We cannot use this sensor at the top of Mount Etna, just in case we work in a research project related to volcanoes.

We will use the two pins labeled SDA and SCL to connect the data and clock lines of the I2C bus to the corresponding pins in the digital temperature and humidity breakout board. After we finish the necessary wirings, we will write a Python code to measure, display the ambient temperature, and the relative humidity. This way, we will read the result of sending commands to the sensor through the I2C bus, reading the responses, and decoding them into the ambient temperature and...
