Third, the pin and instructions

Pin Name Function Description
1 ANT Antenna Interface
2 GND power supply negative
3 GND power supply negative
4 DATA Data Output
5 VCC power supply positive
Five pins, from left to right is ANT, GND, GND, DATA, VCC when it receives a valid signal, are high output signal.

Fourth, the application environment
Electric Road gate, retractable doors, garage doors, gates, automatic doors, sliding doors and other gated areas and other AC motors, DC motors remote control field, on the stability and anti-jamming very demanding and rigorous field and the environment.

V. Remarks

Antenna with a soft wire or other hard metal (like telescopic antenna), the length of neither too long nor too short, otherwise it will affect the receiving distance. If you use soft wire, please straighten use, and try not to close metal objects. Supply voltage for stability and low ripple factor, to be multi-stage filter (such as increasing the bead capacitors, inductors).

When used with the recommended single-chip MCU clock frequency and the crystal in the following 4MHz possible from the RF receiver module, otherwise the higher harmonic crystal affects the communication distance.

Antenna length: 24cm (315MHz), 18cm (433.92MHz), we need the other frequency antenna length test, in order to achieve optimum reception.
