Review on 🌡️ Weewooday 6-Piece W1209 Micro Digital Thermostat Temperature Controller Board with Case, 12V DC -50-110°C Electronic Temp Control Module Switch with Waterproof NTC Probe by Alan Singh

Luckily the very first unit I assembled burned out straight away! What I've learned is that the turn-off circuitry depends on the LED to power the logic input of any gate, which actually turns the relay off. So when your LED goes off, make sure your hardware keeps running even if you want it to shut down. . OTHERWISE, DO NOT USE this product for things that could be harmful if left unchecked! Now that I've saved you from incalculable expenses, let me tell you what a fun, awesome, easy, and intuitive deal this is. I just assembled a small oven for curing resin and sanitizing masks. (A 75 watt downlight connected to two old styrofoam covered aluminum pans) This controller does a great job of adjusting the light. Just make sure operations are controlled.
