Raspberry Pi Remote Temperature Sensor

To enable the R&D team to have continuous temperature monitoring of the server room (for their R&D Cloud).


The R&D team created and implemented a low-cost and efficient continuous temperature monitoring solution for their server room. The solution used a Rasperry Pi (Pi). The Raspberry Pi is an inexpensive, credit card-sized, single-board computers developed in the United Kingdom by the Raspberry Pi Foundation with the intent to promote the teaching of basic computer science in schools and developing countries. The team enhanced the Pi with a temperature and humidity sensor and enabled the Pi to send continuous readings to the team’s custom developed dashboard, known as project Sauron.
