Temperature Sensor Module


Stock status: last-time-buy (temporary hiatus)
Due to the global electronics parts shortage, some components required to assemble this product are either unavailable or have risen significantly in price. When existing stock runs out we can't assemble any more.

We will resume production the moment that parts become available again. In the meantime, we can't guarantee any future supply after existing stock runs out.


Sprinkle these around your house to collect temperature data using your Arduino. This DS18B20-based 1-wire bus temperature sensor module is easy to connect and use, and you can even daisy-chain several together on the same wire. 0.5°C accuracy and fast response.

The DS18B20 temperature sensor used on this module was featured in the book "Practical Arduino" in the Online Temperature Sensor project, so this module is perfect for building that project. We've also written up an updated version of that project using our Ethernet Shield with PoE Support, complete with example code that makes it almost a copy-and-paste exercise to add these to your home automation system or datalogger!
