Smart Iron box 1

Circuit and working

As shown in Fig. 2, the circuit built around Arduino Uno Board1 includes single-changeover relay module MOD1, MPU6050 module MOD2, mercury tilt switch module MOD3, 12V power supply, and a few other components. The block diagram is shown in Fig. 3.

The output is connected to a single-channel relay board, which is connected to a 3-pin electrical socket for connecting to the electric iron. A bypass switch is used to bypass the relay board whenever smart action is not required. A 12V supply is used to power the Arduino board.
