So I have this idea to build a type of fire sensor. I got it from a friend at school, he said that it was too hard, im gonna give it a shot. I will attach a rough diagram to this text. I will be using cheap sensors, and small candles. I know that the sensors do in some way pick up the flame, but the picture I have attached is not my own. It does however point out the values that the fire changes. I have accepted that under 100 of these values is close or 'critical' fire. This will be a small model, but enough to get the idea across. The idea being that if any 2 sensors pick up those specific values under 100, it should give me some kind of warning. If I should go into any further detail, or name each sensor on the diagram, then I would be perfectly happy to do so. The part number of the sensors I am using are the BPT-BP0914, since part number seemed to be the most detailed name I could get. It says the 'code' of these sensors are 14C0633. I have started with the coding abit, and have an Arduino Mega and Uno, as well as loads of extras, so those wont be a problem. The coding I need help with was mentioned above, my problem simply being I am not sure how to program the arduino to get it to give me a warning if there is a infrared source detected by atleast 2 sensors. If you want to view the sensors, they are these BPT-BP0914 - IR PHOTOTRANSISTOR sesnor 5mm BL 940n RX
I am not sure if that is clickable, please inform me how to do it correctly if it isnt, I am still a beginner here.
