How is it wired?
Wire it in series with the heater or motor you want to protect, so opening the contacts cuts power to the load. Use insulated wiring rated for the voltage, and never connect the mains side directly to Arduino or ESP32 pins.
Can it be used as a thermostat?
No. It is an over-temperature cut-off that opens at a fixed trip point, not a thermostat for holding a set temperature. Mount it in good thermal contact with the part being protected, such as a heater or motor housing.
