Using TX05C new infrared burglar alarm circuit diagram

A new type of infrared system utilizes the TX05C radio sensor module for a burglar alarm designed for doors and windows. This system operates in the infrared spectrum, which is invisible to the human eye, making it suitable for wireless surveillance applications. It provides robust security and reliability; when an individual enters the monitored area, their body obstructs the infrared beam, triggering a loud alarm to alert the security personnel. This circuit is not limited to doors and windows but can also be implemented for walls, fences, and other areas requiring monitoring. The infrared monitoring burglar alarm circuit diagram includes several components: an integrated circuit, alarm speakers, and a power supply. The power circuit consists of a transformer (T), rectifier diodes, and a three-terminal regulator (IC4), which provides a stable 12V DC output for the entire system. The infrared transmitter module (IC1) contains power management devices, integrated circuits for password protection, an infrared modulation circuit, and infrared emitting diodes. These components work together to emit modulated infrared signals through a lens aperture. The supporting infrared receiver module (IC2) monitors the presence of infrared signals. When the monitored area is clear, IC2 receives the infrared output, keeping the transistor inside IC1 off, resulting in a high signal output from IC3, and the alarm speaker (BL) remains silent. If someone enters the monitored space, they block the infrared radiation from IC1. Consequently, IC2 fails to receive the infrared signal, turning on the transistor inside, which triggers pin 2 of IC3. This change causes IC3 to enter a set state, producing a high output on pin 3 and activating the alarm speaker (BL) to emit a loud sound. The system operates on a 12V positive supply that charges capacitor C4 through resistor R2. After approximately 2 minutes, the voltage level rises to a threshold that resets IC3, returning the circuit to its initial state.

The circuit operates effectively by combining infrared technology with a reliable alarm mechanism. The TX05C module serves as the core detection component, ensuring that any interruption in the infrared beam is detected promptly. The power supply circuit is crucial for maintaining stable operation, utilizing a transformer to step down the voltage and rectifier diodes to convert AC to DC. The three-terminal regulator ensures that the output voltage remains consistent, which is vital for the performance of the infrared transmitter and receiver modules.

The infrared transmitter (IC1) is designed to emit a modulated signal that can be recognized by the receiver (IC2). This modulation helps to differentiate between the alarm signal and potential noise, ensuring that only genuine interruptions trigger the alarm. The integration of a one-shot circuit (IC3) allows for a timed response to the alarm condition, providing a delay before the system resets. This feature prevents false alarms caused by brief interruptions, such as small animals or environmental factors.

The alarm speaker (BL) is selected for its loud output, ensuring that the alert is noticeable in the vicinity of the monitored area. The circuit's design allows for flexibility in installation, making it suitable for various applications beyond just doors and windows, including outdoor fences and indoor spaces requiring monitoring. Overall, the combination of infrared technology, integrated circuits, and a robust alarm system creates a reliable security solution for diverse environments. But here is a new type of infrared using TX05C radio sensor module made of doors and windows burglar alarm. Because it is not visible to the human eye utilizing infrared, wirel ess surveillance composition region, and therefore have a strong security and reliability, as long as someone enters the surveillance area, the body is bound to block the infrared beam, then the circuit will emit a loud alarm sound, to call attention to the duty officer. This circuit except for the windows and doors burglar alarm, but also can be used for walls, fences and other occasions need to be monitored.

Infrared monitoring burglar alarm circuit diagram shown below, when the base integrated circuit, alarm speakers and power supply circuit of several parts of its circuit mainly by the infrared transmitter and receiver modules. Power circuit from the transformer T, rectifier diodes, three-terminal regulator IC4 hub and other parts, stable output voltage of 12V DC power supply of the entire circuit.

IC2 is supporting the infrared receiver module. When no one entered the monitoring area, IC2 receives infrared output terminal OUT module inside the transistor is turned off IC1 emitted is high, then the one-shot circuit from when base integrated circuit IC3 composition in the reset state, 3 feet without output, alarm loudspeaker BL silent.

If a person enters the monitored area, it will block the infrared radiation emitted by IC1, IC2 long once did not receive IR commands, OUT-side transistor is turned on inside that trigger Pin 2 of IC3 is triggered by the low, one-shot flip Now into the set state, 3 feet high output, VT conduction, BL electrical work, it will send a loud alarm sounds. In this case 12V positive supply to charge C4 through R2, after about 2min, value end level rises to 6 feet 2 encoding/3, IC3 reset, 3 pin output low, the circuit returns to the original stationary state.
