    Fire alarm circuit ABSTRACT Here is a simple fire alarm circuit based on a Light Dependent Resistor (LDR) and lamp pair for sensing the fire. The alarm works by sensing the smoke produced during fire. The circuit produces an audible alarm when the fire breaks out with smoke. When there is no smoke the light from the bulb will be directly falling on the LDR. The LDR resistance will be low and so the voltage across it (below 0.6V). The transistor will be OFF and nothing happens. When there is sufficient

    a Simple Temperature Display Circuit using LCD ( Liquid Crystal Display ). For Heat Sensor we have used IC LM35 (Precision Centigrade Temperature Sensors ) whose Output voltage is linearly proportional to the Celsius (Centigrade) temperature. Output of LM35 IC is 10mv/degree centigrade for eg if temperature is 35 degree then the output of sensor will be 350mv or 0.35V For working with LCD it is necessary to have Microprocessor. We have used Arduino Controller Board which is AN OPEN-SOURCE ELECTRONICS
