Intelligent iron control circuit

Intelligent iron control circuit

Shown is the smart iron control circuit . In this circuit, the integrated circuit PT8A351X controls the relay and light-emitting diode
by identifying the iron placement direction detection switch. When the iron is placed horizontally, the @ pin is high , and the iron automatically ; When the iron is placed vertically, the @ pin is low level (grounded), and the iron automatically cuts off power in about 10 minutes.
