This is a system that detects intruders with any sensor, transmits the information to a receiver via wireless communication, and alerts with a buzzer and sensor number. It is a measure against crop theft and other issues.
In the past, there were many damages to crops caused by animals, but recently, there have been reports of significant damage to high-priced fruits during the harvest season for farmers. Additionally, there have been numerous reports of copper wire theft at solar power plants, which has been distressing. 【Function】 It constantly monitors the status of the sensors and alerts to any changes. Communication is updated every three seconds, and the receiving LED blinks each time, allowing confirmation that the signal is being received. When an anomaly occurs, a buzzer sounds immediately, and the LED for the anomaly channel lights up. If the system is damaged and the signal is interrupted, the buzzer will sound after about one minute. 【Sensor】 Wide-range sensor: Thin enamel wire or Teflon wire is laid out in appropriate places. It reacts when a person or animal cuts this wire. It can be stretched up to 500 meters without issue. Infrared temperature sensor Ultrasonic reflection sensor Wireless reflection sensor Simple switch Please install and use sensors that match the above locations and detection methods.
