Hi everyone, I'm working on a flame sensor project. Ive seen many sensors that can detect flame even under the sunlight. Those were IR-UV sensors.what is the principle of these sensors. I tried both of those sensors but it didn't work for me. How can I detect the flame and disable the sunlight's effect. Those sensors are working by detecting the ir and uv waves which are coming from the flame. But as you know sun is the biggest ir and uv wave source. So all sensors that I've tried ended up with fail. I need your suggestions and advice. Can you help me please?
