It can detect flame or light source with in the range of 760 nm to 1100 nm. The flame distance of the lighter is 80 cm. The larger the flame, the farther the test distance is. 2, the detection angle is about 60 degrees, which is particularly sensitive to the flame 3, the sensitivity is adjustable (blue digital potentiometer adjustment in the figure) 4, the comparator output, the signal is clean, the driving ability is strong, more than 15mA 5, with adjustable precision potentiometer to adjust sensitivity 6, working voltage 3.3V-5V 7, output form: digital switch output (0 and 1) and voltage output 8, with fixed bolt holes for easy installation 9, small board size: 1.26inchx0.56inch/3.2cm x 1.4cm 10. Use a wide voltage LM393 comparatorPackage Included: 5pcs IR Infrared Flame Detection Sensor Modulesbr>Module instructions: 1. The flame sensor is most sensitive to flame and is also active to ordinary light. It is generally used for flame alarms and other purposes. 2, the small board output interface can be directly connected to the port of the microcontroller 3. The sensor and the flame should be kept at a certain distance to avoid damage to the sensor at high temperature. The flame distance of the lighter is 80cm. The larger the flame, the farther the test distance is. 4, small board output mode can achieve higher precision ## Features - Make sure this fits by entering your model number. - Usage:Apply for Various flames, fire source detection. The module can detect flame or light source with wavelength in the range of 760 nm to 1100 nm. The flame distance of the lighter is 80 cm. The larger the flame, the farther the test distance is.Used for fire alarms, etc - The detection angle of the module is about 60 degrees, which is particularly sensitive to the flame with adjustable precision potentiometer to adjust sensitivity(blue digital potentiometer adjustment in the figure) - The comparator output, the signal is clean, the driving ability is strong, more than 15mA - Working voltage 3.3V-5V. Output form: digital switch output (0 and 1) and voltage output.Use wide voltage LM393 comparator - Note:Keep the sensor and flame at a certain distance to avoid high temperature damage to the sensor.The small board output interface can be directly connected to the port of the microcontroller.Small board output mode and conversion processing for higher precision ## Images ![LGDehome 3.3V-5V IR Infrared Flame Sensor 4 Pin Infrared Detection Module Detecting Distance 80cm (Pack of 5) - Image 1](https://m.media-amazon.com/images/I/611KfQk6yaL.jpg) ![LGDehome 3.3V-5V IR Infrared Flame Sensor 4 Pin Infrared Detection Module Detecting Distance 80cm (Pack of 5) - Image 2](https://m.media-amazon.com/images/I/61qJBcy6RsL.jpg) ![LGDehome 3.3V-5V IR Infrared Flame Sensor 4 Pin Infrared Detection Module Detecting Distance 80cm (Pack of 5) - Image 3](https://m.media-amazon.com/images/I/51hAS-QMd2L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ great product for Arduino classes *by C***N on Reviewed in the United States 🇺🇸 on December 14, 2019* this sensor is very well designed and works very well for my introductory Arduino class. I will be buying this product for future classes and to keep in stock for our maker lab. item was shipped very quickly and each sensor was individually packed in an ESD bag unlike some of the other sensors I have purchased in the past. ### ⭐⭐⭐⭐⭐ Works as Expected *by R***Y on Reviewed in the United States 🇺🇸 on December 12, 2019* I received the wrong voltage regulator and reordered to get the correct one. The regulator works as expected. ### ⭐⭐⭐⭐⭐ Great *by A***R on Reviewed in the United States 🇺🇸 on December 28, 2019* Worked great, good price for quantity --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/146815762-lgdehome-3-3v-5v-ir-infrared-flame-sensor-4-pin](https://www.desertcart.pt/products/146815762-lgdehome-3-3v-5v-ir-infrared-flame-sensor-4-pin) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-10-30*
