Build your own Maxim iButton controller with Arduino

Technology enthusiast Jeff Miller needed a device to control Maxim iButton data loggers – and instead of purchasing a commercial unit rose to the challenge and made his own. Using an Arduino board and external hardware, the device can stop, start and read iButton devices as well as 1-wire temperature sensors (such as those used on our TEMP: module). FInally the project looks great in a neat enclosure. Find out more in Jeff’s video below:

If you’re looking for a 1-wire temperature sensor, consider our Freetronics TEMP: module:

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. With a range of -55 to +125°C at +/-0.5°C accuracy it’s suitable for almost every temperature-measurement project. For more information and to order,click here
