Product Name: 5 VDC high-frequency four super-regenerative receiver module ,
The technical parameters:
Product characteristics :
Super-regenerative receiver module using LC oscillator circuit , containing amplification shaping, the data signal output is high signal decoded , extremely easy to use and inexpensive, it is widely used. With four decoded outputs ( also can be changed to six-way jog or interlocking output ) , easy to use ; frequency debugging easy , short lead times ; product quality, consistency, and cost-effective.
Receiver module has a wide receiver bandwidth, typically ± 10MHz, 315MHz factory usually tune in or 433.92MHZ ( if any special requirements to adjust the frequency adjustment range , the frequency of 266MHz ~ 433MHz.). Receiver module generally use DC5V power supply, adjustable voltage range of any special requirements .
Pin and instructions :
Receiving a total of eight external interface module , above the English said . "5V" indicates positive power supply , "D0, D1, D2, D3" represents the output , "GND" represents negative one , "ANT" means an antenna connection terminal .
Before use to connect a 50 ohm 1 / 4 wavelength antenna , and the antenna should be straight , in order to achieve the best reception, wavelength = speed of light / frequency .
The application environment ( applications )
Wireless remote control switch , remote control socket , data transmission, remote control toys , burglar alarm host , garage doors, gates , road gates, retractable doors gated industry and its remote audio fields.
With the company launch series , supporting the use of remote control products .
VCC voltage to be consistent with the module operating voltage, and power to do the filtering ;
Impact on the reception antenna module is large, then the best 1/ 4 wavelength antenna , generally use 50 ohm single wire antenna length 315M is about 23cm, 433M of about 17cm;
Also affect the position of the antenna reception module , install the antenna stretched as far as possible away from the shield , high pressure, and local sources of interference ;
When using the reception frequency , the transmitter should match decoding
