Title: ppt on fire alarm using thermistor circuit Page Link: ppt on fire alarm using thermistor circuit - Posted By: siyad R Created at: Thursday 17th of August 2017 05:45:28 AM	fire alarm using thermistor working principle, abstract for fire alarm using thermistor mini project, circuit for fire alarm circuit system using microcontroller 8051, disadvantages and advantages of fire alarm using thermistor, multichanel fire alarm circuit based on plc circuit for multichanel fire alarm systm, project report on fire alarm using thermistor submitted by university, abstract for fire alarm using thermistor in mini projects,
Many fire alarm circuits are presented here,but this time a new circuit using a thermistor and a timer to do the trick. The circuit is as simple and straight forward so that, it can be easily implemented. The thermistor offers a low resistance at high temperature and high resistance at low temperature. This phenomenon is employed here for sensing the fire. The IC1 (NE555) is configured as a free running oscillator at audio frequency. The transistors T1 and T2 drive IC1. The output (pin 3) of IC1 is couples to base of transistor T3 (SL100), w ....etc [:=Read Full Message Here=:]

Simple Fire Alarm Circuit Here is a simple fire alarm circuit based on a 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 .6V).The transistor will be OFF and nothing happens.When there is sufficient smoke to mask the light from falling on LDR, the ....etc [:=Read Full Message Here=:]
