Alarm System for Entrance/Exit Gate
The circuit operates by integrating reed switches, which are sensitive to magnetic fields, into an alarm system designed to monitor the status of a gate. When the gate is opened or closed, the position of the gate alters the magnetic field surrounding the reed switch. This change triggers the switch to either open or close, allowing current to flow through the circuit.
The power supply for the circuit is a universal AC/DC power supply oscillator, which provides the necessary voltage and current to operate the alarm system. This type of power supply is versatile, capable of accepting various input voltages and converting them to a stable output suitable for powering electronic components.
In the alarm configuration, the reed switch is typically connected in series with a signaling device, such as a buzzer or an LED indicator. When the reed switch is activated due to the movement of the gate, the signaling device is energized, alerting users to the gate's status.
In addition, the circuit may include additional components such as resistors to limit current, capacitors for noise filtering, and diodes for protection against reverse polarity. These components enhance the reliability and functionality of the gate alarm system, ensuring it operates effectively in various environmental conditions.
Overall, this design provides a simple yet effective way to monitor gate access, enhancing security and awareness for users.The circuit employs the functions of reed switches to produce a gate alarm that is powered by a universal AC/DC power supply Oscillator . 🔗 External reference
