This temperature probe contains a DS18B20 digital thermometer sealed inside a stainless steel sheath. Perfect for accurate temperature measurements in wet environments. The probe has a 3-core cable attached to it, allowing you to keep any connected electronics a safe distance away from whatever it is you are measuring.
The DS18B20 provides 9 to 12-Bit (configurable) temperature measurements and also features an alarm function with non-volatile user-programmable upper and lower trigger points. It is able to communicate over a 1-Wire bus that by definition requires only one data line (and ground) for communication with a central microprocessor. Power can be supplied via the VDD wire, or directly from the data line (parasitic power) – in the second method only two wires are required instead of three. Lastly, each DS18B20 has a unique 64-bit serial code which allows multiple DS18B20’s to function on the same 1-Wire bus. This makes it a simple task to use one microprocessor to control many DS18B20’s distributed over a large area.
