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=:]

In the past, hardwired alarm systems are the only choice for customers who need security equipment to protect premises. Today, with rapid technology evolve, many users shift from hardwired alarm to wireless alarm. It seems home security industry is moving from hardwired to wireless, but as one of mature and stable alarm equipment, some users still favor the hard wired alarm system. In this article, we will show you some basic information about advantages and disadvantages of hardwired alarm systems. What s hardwired alarm system ? Alarm ....etc [:=Read Full Message Here=:]

The circuit illustrated here is used as Burglar alarm. LDR is kept at such a place that when thief enters our house then a shadow will fall on the LDR. A small beam of light source is also needed to supply continuous signal to LDR. For best Light source we can use Laser diode which will work for few km. For home use Infra Red LED s will be good and will be tricky to thief and works with same efficiency at night. This circuit uses a popular timer I.C which is 555. I.C 555 is connected as comparator with pin 6 connected with positive supply, t ....etc [:=Read Full Message Here=:]

fire alarm using thermistor advantages and disadvantages 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), which drives the speaker to generate alarm sound. The frequency of NE555 depends on the values of resistances R5 and R6 and capacitance C2. When thermistor becomes hot, it gives a low-resistance path for the positive voltage to the base of transistor T1 through diode D1 and resistance R2. Capacitor C1 ....etc [:=Read Full Message Here=:]
