DS18B20 - 1Wire Digital Thermometer   Description The 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 microprocesso..

A Sensor or a Detector is a device that is used to convert a physical parameter into a signal that can be measured or monitored. For example a GAS Sensor monitors gas concentration (PPM) and converts it into electrical signal that can be measured. The input parameter can be different like Light, Temperature, Humidity pressure etc but the output is generally a human readable or electrically monitarable. 

A sensor is classified based on various aspects such as

        • Application Based:  Industrial Sensor, Automotive Sensor etc

        • Output Based : Resistive output, Differential Output, Differential output, voltage output etc

        • Parameter Sensing Based: Light, Temperature etc
