We usually install security system to help us to monitor the farm. Use infrared movement sensor and ac lamp to make a simple security system, for instance. It’s easy to wire and operate. But if the infrared movement sensor is installed at the door of the farm for monitoring, and the lamp need to be placed inside the farm for warning intrusion. There is a long distance between each other. So the sensor cannot be wired to the lamp directly. They need a wireless signal to work together at this time.
The long distance rf remote transmitter CB-2N is strongly recommended here. It has two extended wires. With the connection and disconnection of two wires, the rf remote transmitter can send out an rf wireless signal “ON” and “OFF”. It pairs with rf receiver S1PX-AC220-ANT2, which has long range with external magnetic antenna. Transmitting distance of this transmitter & receiver set is up to 2000m in open field.
As seen in the picture, two wires on transmitter should be connected the contacts of the infrared movement sensor. The output contacts of receiver should be connected to the ac lamp.
When someone breaks into the farm, the contacts of sensor are closed; transmitter is triggered and then transmits an rf wireless signal “ON” to the receiver. After the receiver receives the signal, output contacts are closed; the lamp turns on to warn the emergency.
When someone goes out of the farm, the contacts of sensor are cut; transmitter is triggered and then transmits an RF signal “OFF” to the receiver. After the receiver receives the signal, output contacts are cut, the lamp turns off.
