Best 2 Buttons Long Range RF Wireless Remote Control Radio Transmitter

Feature:
This transmitter is a super long range remote control. It is developed by LORA (Long Range) wireless communication technology, so it has ultra-long working distance, ultra-high receiving sensitivity, superior anti-interference ability, and smaller power consumption. It uses a transceiver chip to implement bidirectional communication. Its ideal working distance is up to 5 kilometers, which is an excellent device for remote control and long distance communication.

Application:
The transmitter and the receiver form a wireless remote control system. This system may be used in all types of industry automation, agriculture, business, home, factory, house, farm, garage, vehicle, ship, aerial vehicle, etc. It can remote control different AC or DC equipment on land, water and air, such as lights, doors, windows, lamps, sockets, locks, sirens, outlets, heaters, motors, fans, winches, curtains, blinds, linear actuators,  electric solenoid valves,  and security alarm systems. The applications are endless.

Super Long Working Range:
The transmitter and the receiver form a wireless remote control switch, the maximum working distance may reach 15000 feet or 5000 meters in an open area.
The maximum working distance is a theoretical data, it shall be operated in an open ground, no barriers, no interference. But in the practice, it will be hindered by trees, walls or other construction, and will be interfered by other wireless signals. Therefore, the actual working distance may not reach this maximum distance.

Two-Way Working Mode with Feedback Function:
The transmitter and the receiver have a Two-way working mode, so the user can know the working status of the receiver by the transmitter.
Two-way working mode: When the receiver is successfully triggered by the signal from the transmitter, it will immediately transmit a feedback signal to the transmitter. When the transmitter receives this signal, it will send out a buzzing sound to inform you that the receiver has been successfully triggered.

Matching Receivers:
This transmitter only works with 5000 meters receivers, and it does not work with other ordinary receivers.

How to set the feedback function:
You first open the case of the transmitter, then you will see a jumper J1 on the circuit board.
You can retain the jumper J1 to activate the feedback function; or remove the jumper J1 to deactivate the feedback function.

Notice:
1. Please fully extend the telescopic antenna to get the best working range.
2. Please turn off the power switch if you don’t use the transmitter for a long time.
3. Replace the transmitter's battery if the transmitter's signal LED is weak or the working distance is shorter.
