An easy way to control a winch remotely

We usually use winch to help us to hoist heavy stuff to higher place or drop to lower place. For example, farmers always store the grain in the warehouse in every harvest season. But the warehouse sometimes is an attic. They usually have to hoist grain bag to the attic by themselves in the past. Actually, that is energy-consuming working. It is too difficult for aged farmers to hoist those heavy bags of grains now. So they want to know if there is an easier way to hoist grain.

The rf momentary motor remote  controller is strongly recommended here. The major characteristic of this receiver is to make the motor in the winch rotate in positive and reversal direction. That is to say, the rope of winch will be stretched out and drawn back by wireless remote controller. The transmitter is also easy to use.

Here are transmitter and receiver.

The following is the application circuit of receiver.

From the wiring picture, the wires from the winch are connected to the receiver. We hook up the bag, pressing and holding button ▲ on transmitter. With the motor of winch working continuously in the “UP” direction, the rope is drawn back and the bag is hoisted; When the bag is lifted to the attic, release button ▲, the motor of winch stops working. After putting away the grains bag, we press and hold button ▼ on transmitter, the motor works continuously in the “DOWN” direction , the rope is stretched out and then it reaches the ground.

How to use infrared motion sensor to remotely control electric fan on and off?

Now we are promoting a brand new product, rf wireless remote control model of CB-2N. This is a long distance remote controller. Transmitting distance is up to 1000m in open field. The major characteristic of it is that it has two extended wires, which is wired to the electrical device. When two wires are connected, the remote will send out an rf signal “ON”. When two wires are cut, the remote will send out an rf signal “OFF”. It can be paired with the receiver, such as S1PX-AC220-ANT2, used in such a situation when you want to use an electrical device to remotely control another device. For instance, use an infrared motion sensor to remotely control the electric fan by the remote & receiver set.

The infrared motion sensor could be used to directly control the electric fan. But if there is a long distance between the infrared motion sensor and the fan, it is inconvenient for wiring. You’d better use our remote & receiver set at this time.

Then how to make infrared motion sensor remotely control the electric fan by our remote controller? Next we’ll talk about it.

Look at the wiring picture, two extended wires on transmitter should be connected the contacts of infrared motion sensor. The wires from fan should be connected to the output contacts of receiver.

When someone enters into the detective range, the contacts of infrared sensor are closed; transmitter is triggered and then transmits an rf signal “ON” to the receiver. After the receiver receives the signal, output contacts are closed; the fan starts to work.

When someone goes out of the detective range, the contacts of infrared sensor are cut; the transmitter is triggered and then transmits an rf signal “OFF” to the receiver. After the receiver receives the signal, output contacts are cut, the fan stops working.
