SparkFun SEN-11050 Temperature Sensor – Waterproof (DS18B20)

This sealed digital temperature probe lets you precisely measure temperatures in wet environments with a simple 1-Wire interface. The DS18B20 provides 9 to 12-bit (configurable) temperature readings over a 1-Wire interface, so that only one wire (and ground) needs to be connected from a central microprocessor.

Dimensions: Probe is 7mm in diameter and roughly 26mm long. Overall length (including wire) is 6 feet.

  1. Mike McPherson

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

  2. Robert Pin

    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.

  3. Sam Culley

    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
