dallas waterproof temperature sensor ds18b20 probe price  

DS18B20 digital thermometer provides 9-bit to 12-bit Celsius temperature measurements and has an alarm function with nonvolatile user-programmable upper and lower trigger points. The DS18B20 communicates over a 1-Wire bus that by definition requires only one data line (and ground) for communication with a central microprocessor. In addition, the DS18B20 can derive power directly from the data line (“parasite power”), eliminating the need for an external power supply. Each DS18B20 temperature sensor has a unique 64-bit serial code, which allows multiple DS18B20 to function on the same 1-Wire bus. Thus, it is simple to use one microprocessor to control many DS18B20 sensors distributed over a large area.Application that can benefit from this feature include HVAC environmental controls, temperature monitoring systems inside buildings, equipment, or machinery, and process monitoring and control systems.
