Sensor Options:
 
Quantity:
R 32.00 each Estimated Dispatch Tomorrow Total Cost R 32.00

Product Description

This 1-Wire digital temperature sensor from Maxim IC (DS18B20) can be interfaced to with just one wire. With a ground connection, the device communicates and draws its power through a digital data line. Each sensor has a unique 64-bit serial number, meaning that many sensors can be connected to the same data bus.

 

Waterproof Probe:
* The waterproof probe is made of stainless steel and has a cable length of 1m.
* Stainless steel housing dimensions: 6 x 50mm
* Cable maximum operational temperature is +85°C
* Cable configuration: Red (Vcc), Yellow (Data), Black (GND)
