complete info about fire alarm sys using ic555 The purpose of a fire alarm system is to detect the unwanted presence of fire by monitoring environmental changes (such as temperature changes) associated with combustion. The Fire Alarm presented here is a simple fire detecting circuit employing a germanium diode (DR25) as the fire sensor (Thermistor in the circuit diagram should be replaced by this germanium diode). This fire detecting sensor utilizes the simple fact that in case of fires the room temperature rises rapidly, reaching temperatures ....etc [:=Read Full Message Here=:]

This simple Touch Switch is developed by using 555 timer IC operated as a MONOSTABLE vibrator. Here the stable stage is LOW, so the timer outputs low after the trigger is removed. Basically in this circuit we will have a LED which turns ON when we touch a pin of timer. The LED will be ON for the time during which the trigger is present. Once the trigger is removed the LED turns OFF.

This power failure alarm project is a power supply monitoring device that will trigger a buzzer when the mains supply cuts off. At the same time, the light emitting diode will be turned ON. This device is helpful to inform the loss of power supply to some critical installation such as a pump in a fish tank. Once the buzzer sound, you will know that there is a loss of power supply and actions need to be taken to rectify the situation by providing alternative power supply or relocating the installation. ....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=:]
