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

Short Assignment 1 * What was the positioning challenge Apple faced? Competitors enter market * In 1981‚ IBM entered PC market used Microsoft’s DOS OS and microprocessor and will be Apple best rival for the start on 1981. Jobs forced out in 1985. * In 1985‚ Compaq and IBM do a research and development (R&D) and make move Apple into the mainstream by becoming low-cost producer and joint venture with IBM. This’s one of Apple failure moment and Apple Gross margin drop to 34%. *

Here is 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

PHY 156 4870 Lab Report #6: RC Circuits October 14th‚ 2011 Objectives: The purpose of this lab is to observe the charge and discharge curves of a capacitor and determine its time constant. The capacitor is observed with respect to the voltage traveling through the capacitor. Principles: One of the main principles of this experiment is defined by V = VB [1 – exp (-t/RC)] for a charging capacitor and furthermore‚ τ is defined by resistance multiplied by capacitance(R * C). Thus
