Wireless control, easy to install.
It adopts spread spectrum communication technology, which greatly improves the anti-jamming performance.
It can be used as a transmitter module or as a receiver module.
Ultra-high receiving sensitivity, super long working range.
Three working modes.
Four channels input / output.
With feedback buzzer and feedback output pin.
With external antenna, the module has a farther working range.
The transmitter module can control the receiver module from any place within a reliable working distance.
The wireless RF signal can pass through walls, floors, doors or windows, but it will lose some operating distance.
One or several transmitter modules can simultaneously control one or several receiver modules.
Two or more transmitter receiver systems can be used in the same area.
Bidirectional Mode with Feedback Function:
The module has a feedback function, so the user can know the working status of receiver module by the buzzer of transmitter module.
When the receiver module is triggered by the signal from the transmitter module, it will immediately transmit a feedback signal to the transmitter module, then the transmitter module will send out a buzzing sound to inform you that the receiver module has been successfully triggered.

Working Range:
Super long working range: Two modules form a transmitter receiver system, the maximum working distance can reach 5000 meters in an open area.
The maximum working distance is based on theoretical data without obstacles and any RF interference. In practice, it will be hindered by trees, walls or other construction, and will be interfered with by other wireless signals. Therefore, the actual working distance may not reach this maximum distance.
Usage:
Two modules form a complete kit, one as a transmitter module and the other as a receiver module. Therefore, customers should purchase at least two modules.
Note: This module is not compatible with normal RF transmit or receive modules, such as the modules of fixed code, learning code, or rolling code.
Setting Operating Mode:
1) Set the module to work as a transmitter module:
If you want to set the module to work as a transmitter module, you need to turn off the fourth bit dip switch.
When a data pin of the transmitter module is connected to the VCC pin or DC 3.3V power, it will emit a corresponding wireless signal.
2) Set the module to work as a receiver module:
If you want to set the module to work as a receiver module, you need to turn on the fourth bit dip switch.
When the receiver module is triggered by wireless signal of the transmitter module, its corresponding data pin will output DC 3.3V voltage.
