Flame sensor module relay module fire alarm

The Flame sensor module with relay combines an infrared flame detector and an onboard relay on one board. When the sensor sees the infrared light from a flame, the relay switches, so it can sound a buzzer, turn on a warning light or start a pump or fan without any microcontroller. It is a simple building block for fire alarm demonstrations, safety projects and STEM lessons.

Flame sensor module Specifications

• Sensor: infrared flame detector
• Output: onboard relay with contacts for an external load
• Operation: standalone, the relay switches when a flame is detected
• Detection: flames in front of the sensor, such as a lighter or candle

Flame sensor module Applications

• Fire alarm demonstrations and safety projects
• Switching a buzzer, siren or warning light
• Starting a fan or pump in fire-fighting robot projects
• STEM lessons on sensors and relays

What's in the Box

• 1 × flame sensor relay module

Tip: Check the module's rated supply voltage (5 V and 12 V versions exist) and the contact rating printed on the relay before connecting a load. Sunlight and halogen lamps also emit infrared light and can trigger the sensor, and this is a hobby detector, not a certified fire alarm.
