Uses: Various flame, fire detection Module Features: One can detect a flame or in a 760 nanometer wavelength of ~ 1100 nm range of the light, lighter flame test distance of 80cm, for the greater flame, the farther the distance test 2, the detection angle of 60 degrees or so, particularly sensitive to the flame spectrum 3, sensitivity adjustable (shown in blue digital potentiometer adjustment) 4, the comparator output signal clean, good waveform, driving ability, more than 15mA 5, with adjustable precision potentiometer sensitivity adjustment 6, the working voltage of 3.3V-5V 7, the output format: digital switching outputs (0 and 1) 8, a fixed bolt holes for easy installation 9, small plates PCB Size: 3.2cm x 1.4cm 10, using a wide voltage LM393 comparator Module for use: 1, the flame sensor flame most sensitive to ordinary light is also a rection, generally used as a flame alarm purposes. 2, a small plate output interface can be directly connected to the microcontroller IO port 3, with the flame sensor to maintain a certain distance, so as not to damage the sensor temperature, the flame of a lighter test distance 80cm, for the greater flame, the farther the distance test

It works...Kind of!
I was trying to use this as a pilot flame detector for a water heater. The first problem is (as of 04/22/2021), there is no product data sheet available to guide in the adjustment of the sensor. The second problem is that in order to detect a natural gas pilot light, it has to be within .75" (19mm) from the flame, Where it is to hot to stay without causing damage, and would destroy it in seconds when the burner kicks on.It picks up on propane, butane and large natural gas flames beautifully. It even has no problem with incandescent, and full spectrum light bulbsIf you want to use it to detect full on flames, or even propane pilot lights, than this would probably work. Natural gas pilot lights just don't put out enough light to trip this sensor.

They can see fire.
These work as advertised.Note that they have a limited range and you may need to experiment to see if they will work in your application..

NICE
very very nice used it to build a robot to detect flames to put out
