handy waterproof temp sensor
Monday, 21 August 2017  |  Mike

works perfectly
the waterproofing makes it a bit slower to respond than the bare device
but it does keep the water out!

Robust looking functional piece of kit

No problem getting this sensor up and running with a Raspberry Pi on the dining room table. The next step will be to get it installed in the beehive ! Hope the bees don't chew it to death.

Easy to use!
Wednesday, 19 March 2014  |  Sam

The DS18B20 waterproof temperature sensor from Proto-Pic is easy to use and ready for testing with a breadboard. The ends of the wires are pre soldered for easy connection to a breadboard. The cable is extremely long which is suitable for any application
