Description:
1. The blue line is the signal output output by the 358 op amp. If the signal is not vibrated, it is high (the IO port should be pulled up), and if the signal is vibrated, it is low (signal to ground).
2. Red line power: +12V
3. The black line is the ground line

Notes:
If the output is connected to the high level, it needs to add a resistor of 100 ohms or less. If you want to drive the wireless transmitter module, you can not replace the resistor. The red and black wires are connected to the positive and negative power input of the module. The number (DC alarm horn) is preferably an external relay control to avoid large current damage to the sensor internal components (for reference).
