Set Up a Raspberry Pi I2C Temperature Sensor
There are several temperature sensors that are available for your Raspberry Pi one of the most popular being the DS18B20, however, if you are looking for an I2C connected temperature sensor then the Atlas Scientific RTD Temperature sensor is an excellent option. If your project already involves the use of other I2C sensors then this can be easily added in parallel without using any additional GPIO pins on your Pi. This sensor also provides onboard logging capabilities and provides readouts in either Celsius, Fahrenheit or Kelvin, with the addition of a thermowell you will be able to insert your temperature probe into your plumbing.
To configure the Pi I am assuming that you are running the latest version of Raspbian and have the ability to connect to your Pi either through SSH with putty and FTP with Filezilla or directly with a keyboard and monitor. If you haven’t set-up your Pi yet then check out my getting started section.
In this tutorial I will be using the following materials:
