temperature sensor

dsaxe

Looking for a temperature sensor that can wifi information to a web based platform.  Hoping to know when my pipes are about to freeze again, so I can avoid the damage!

    As a practical point, most central heating boilers and controllers are able to fire themselves up when the temperature of the boiler gets too close to freezing. Either one or the other is usually enabled by default, but sometimes they are not.

     

    If you want an almost ready-made Pi solution, the RaspberryPi.org SenseHat device and Node-Red can quickly be set up to send temperature and other data to other devices on your LAN or the Internet. The SenseHat is ridiculously over-featured to make this an economic solution, but Node-Red should be capable of dealing with simpler temperature measurement devices. Node-Red works by setting up a web-server on your Raspberry Pi which you access using a browser and which provides a graphical, drag-and-drop display to connect and process data from the Pi to remote devices.

     

    You can make the temperature measurement easier by buying a low cost Arduino Nano and an Arduino temperature module and programming it via a Pi USB port (the arduino IDE is in the Raspbian repository). Because the Nano is running at 5V rather than the Pi's 3.3v, you have much better sensor choices. Python can then be used to collect the temperature measurements via USB from the Nano and then forward them to the Internet.
