2021年12月14日 · So, in this tutorial, we are going to make a simple “Fire Alarm Circuit”. Every place needs safety. But, some specific places need regular fire safety alarms. For example, industries.

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.

2019年11月6日 · There are many typical and complex fire alarm circuits available in the form of standalone devices. But this tutorial will explain to you a simple fire alarm circuit using LM358. The fire alarm circuit using LM358 is a simple project which detects the fire and triggers the siren sound or a buzzer.

2015年5月28日 · Here we are building one simple fire alarm system with the help of 555 Timer IC, which will sense the fire (temperature rise in surrounding), and trigger the alarm. The key component of the circuit is Thermistor, which has been used as fire detector or fire sensor.

2024年8月3日 · The circuit efficiently sounds an alarm as the temperature rises, signaling a possible fire, by utilizing the temperature sensitive characteristics of the thermistor and the timing capabilities of the IC 555.
