Make A Simple RF Remote Control Alarm System
We usually install alarm system to help us to monitor the farm. Use infrared motion sensor and light to make a simple security system, for instance. It’s easy to wire and operate. But if the infrared motion sensor is installed at the door of the farm for monitoring, and the light 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 light directly. They need a wireless signal to work together at this time. The long distance rf remote control CB-2N is strongly recommended here. It has two extended wires. With the connection and disconnection of two wires, the remote control can send out a wireless signal “ON” and “OFF”. It pairs with ac rf high power receiver S1PX-AC220-ANT2, which has long range with magnetic mount antenna. Remote control distance of remote control & receiver set is up to 2000m in open field. Now let’s see how the remote control & receiver set works out. As...
