If you have a fence that goes all the way around your property, including in front of your driveway, you want to make sure that you can get into your property easily. One way is to have a gate that has sensors on it. There are several different kinds of sensors that you can put on your gate that will let it open and close.
Radio frequency identification chips are small chips that come as transmitters or receivers. They are small enough that they can be put into a keyfob to be carried or built into a lock for the gate. The way that it works is that when the chip reader picks up the chip, it will do what it is ordered to do—open or close the gate. The keyfob can have buttons that will let you choose what to do. If you are in a car, as you are driving towards the gate, the reader will read the chip in your keyfob or in a special unit in your car and open the gate for you. When the reader no longer picks up the chip, it will close the gate. RFID is probably the most secure of the sensors that you can use to get into the gate without having to get out of the car. There are millions of combinations that the chips come in, which makes it harder for them to be bypassed.
With a motion sensor, any time that something above a certain weight and size comes near the sensor, the gate will open. If you are using this for a gate that goes over your driveway, that would mean that pets and animals like deer wouldn't set off the sensor, but people or cars would. If you have a pasture and use an electric fence, you wouldn't want to use a motion sensor because your animals may set it off on accident, and then you have to spend a lot of time chasing them down and getting them back to your property safely.
If you have fenced off your entire property, you need to have a way to get in and out of your driveway. Having some kind of sensor attached to your gate that you can trigger will make it possible for you to get access to your driveway and your property without having to leave your car.
