The DS18B20 IC Digital Thermometer provides -55 C to +125 C. Each DS18B20 has IC 3-pin and used one cable for responding and transmission.. The temperature measurements are stored in 16-bit register and will require a microcontroller for display. Applications that can benefit from this sensor include HVAC environmental controls, temperature monitoring systems inside buildings, equipment or machinery, and process monitoring and control systems.
