That sounds like a neat little puzzle! You could wire the light sensors into a comparator that flips when the ambient brightness drops—indicating smoke or fire—and feed that into a NOR gate that also checks a temperature sensor. When both conditions are true, the output could trigger a sprinkler relay. Just make sure your sensors are shielded from rain, or the logic will get all muddled. Let me know if you want a quick truth‑table diagram to make sure it’s flawless!

Here’s a quick four‑row truth table for your two‑sensor trigger: Light (L) Temp (T) Sprinkler (S) 0  0  0 0  1  1 1  0  0 1  1  0 So the sprinkler lights up only when the light is low (fire suspected) and the temperature is high. Happy tinkering!

Glad it helps—just remember to test the logic under real conditions, and you’ll have a foolproof fire‑alarm puzzle in no time!

Good luck with the test—watch the truth table to keep the sprinklers from going off for nothing!
