Second, product characteristics:

Super-regenerative receiver module using LC oscillator circuit, containing amplification shaping, the output data signal is TTL level, you can go directly to the decoder, extremely easy to use and inexpensive, it is widely used. Products are small, high sensitivity; Frequency debugging easy, short lead times; Product quality, consistency, and cost-effective, wireless remote control market is currently the largest amount of the most widely used high-frequency receiver module. Receiver module has a wide receiver bandwidth, typically ± 10MHz, factory general emphasis on the 315MHz or 433.92MHz (if any special requirements adjustable frequency, frequency adjustment range is 266MHz ~ 433MHz. ). Receiver module generally use DC5V power supply, any special requirements adjustable voltage, the voltage adjustment range is 3 ~ 8V.
Receiver module factory quiescent current typically 4mA, any special requirements can reduce the current, minimum current adjustable from 1.5mA, but the receiver sensitivity will be reduced. Receiver module factory output is noisy output, any special requirements can be changed without noise output, but the receiver sensitivity will be reduced

Fourth, the pin and use:
Pin Name Function Description
1 ANT antenna connection
2 VCC power supply positive
3, 4 DATA Data Output
5 GND power supply negative

Received a total of four external interface module, above the English representation. "VCC" indicates positive power supply, "DATA" indicates that the output, "GND" indicates negative one.

Before use to connect 50 ohm 1/4 wavelength antenna and the antenna should be straight, in order to achieve the best reception, wavelength = speed of light / frequency.

V. Application Environment
Wireless remote control switch, remote control socket, data transmission, remote control toys, burglar alarm host and so on.
Six, optional accessories
And the company launched series, supporting the use of remote control products.
Seven, notes
VCC voltage is consistent with the operating voltage of the module, and the power to do the filtering;
Reception antenna great effect module, then the best 1/4 wavelength antenna, generally 50 ohm single-core wire, the length of the antenna is about 315M 23cm, 433M of about 17cm;
Antenna position also affected the reception of the module, install the antenna stretched as far as possible, away from the shield, high pressure, and the sources of interference; Frequency used to receive, decode mode and oscillation resistance should be matched with the launch
