All rights reserved. current to flow in the item for which the resistance is being measured. This amplifier is suitable for applications that require wide bandwidth and high linearity. where thermistor is used as temperature sensor of fire alarm.Working principle of thermistor is same as LDR (change their resistance with change in heat where LDR change their resistance with change in light fall on it). process is virtually the same in both instances, although readings may not be quite as easy to take. In the absence of base signal, it gets completely off. It will also send the signal to Arduino which processes the signal and set off the alarm along with detection message on display. Once activated, the devices send signals to the fire alarm panel which in turn activates audio and visual devices including lights and sounders. comprise several detection zones. The circuit is realized in CMOS 0.18 mum technology as an asynchronous design with optimized XOR gates and enable encryption signal randomly delayed from cycle-to-cycle. In the mini project category, we have added fire detection alarm system using 8051 microcontroller.
