Flame Alarm DIY Kit Flame Alarm DIY Maker Education PCB Kit

This circuit uses an infrared receiving diode as the sensor for the flame detection part. The circuit uses a 5V DC voltage supply and can be ignited by a lighter 30 cm above the flame sensor to simulate a warehouse fire. In reality when the lighter fire source is close, the buzzer can quickly sound, achieving the alarm function. Only by pressing the alarm elimination button (lightly touching the switch) the alarm sound can be stopped. The kit can be used for practical training for electronic enthusiasts and beginners to enhance comprehensive practical abilities.

It can detect Flame or light sources with wavelength ranging from 760 nanometers to 1,100 nanometers. The larger the flame the farther the testing distance is recommended.

Equipped with adjustable precision potentiometer to adjust sensitivity.

The detection angle is around 60° which is particularly sensitive to the flame spectrum.

Comparator output, clean signal, good waveform and strong driving ability.

working voltage: 3- 5V DC
