Description

Control your projects wirelessly using this radio frequency module. Ideal for controlling Warbots, lifting doors, luminaires. It has 4 outputs that can be connected to switching transistors or optocouplers and then connected to relays. The working frequency is 315 MHz, because it is a free-to-use band.

The antenna has a great influence on the receiver module, so it is recommended to connect a copper cable of about 17cm long to reach the frequency of 315 MHz. The position of the antenna also affects the reception of data. The antenna cable must be properly insulated.

Remote control:

Operating Voltage: 12V DC (Model 27A/12V Battery)
Working current: 10mA to 12V
Radiated power: 10mW to 12V
Modulation mode: ASK
Transmission frequency: 315 MHz (SAW frequency stabilization)
Transmission distance: 50 to 100 meters in open field with -100dBm receiver sensitivity
Fixed code encoder

RF receiver:

Operating Voltage: 5V DC
Receiver Sensitivity: - 98dB
4 outputs (channels)
Pines: GND/VCC/Outputs: D0 D1 D2 D3
Antenna (not included): 25cm~32cm copper wire (recommended in spiral shape)
Dimensions: 6.6 x 22 x 41 mm

OPERATION:

The RF remote control has 4 buttons, each button corresponds to one of the receiver bits (D0, D1, D2 and D3). When a button is pressed, the control transmits the corresponding bit activation signal, and the voltage at the receiver bit is raised to 5V. When the button is stopped pressing, the receiver output returns to the 0V idle state.
