Features:
The regenerative receiving module adopts an LC oscillating circuit, which includes amplification and shaping, and the output data signal is a decoded high level signal, which is convenient to use, low in price, and has four-channel decoding output, and can also be changed into six-way jog or interlock output. Frequency debugging is easy. The receiving module has a wide receiving bandwidth, generally plus or minus 10MHz, and is generally adjusted to 433.92MHz when shipped from the factory. The receiving module is generally powered by DC5V.

Remote control parameters:
Working voltage: DC12V (one grain of 23A/12V battery)
Working current: 10mA@12V
Radiated power: 10mA@12V
Modulation method: ASK (amplitude modulation)
Transmitting frequency: 315MHz (sound table frequency stabilization) Working current: 34mA
Transmission distance: 120-150M (empty ground, the sensitivity of the receiving device is negative 100dbm. The actual distance is generally 40%-70% of the nominal distance)
Encoder type: fixed code

Receive module parameters:
Working voltage: DC5V
Quiescent current: 4.5MA
Modulation method: amplitude modulation (OOK)
Working temperature: -10 degrees Celsius ~ +70 degrees Celsius
Receive sensitivity: -105DB
Working mode: M4 (jog: press and hold without releasing the hand, output will stop when you release your hand)
Coding method: pad code (fixed code)

The four keys on the remote control correspond to the four data output pins on the receiving board.

Instructions for use:
If the distance is far away, the antenna with 1/4 wavelength is generally 50 ohm single-core wire. The length of the antenna is about 23CM for 315M, and about 17CM for 433M. The antenna position also has an effect on the receiving effect of the module. When installing, the antenna should be as straight as possible, away from the shield, high voltage, and where there is interference. When using the receiving frequency, the decoding method should match the transmission.

Product Usage:
Used in wireless remote control switch, remote control socket, data transmission, remote control toy, anti-theft alarm host, garage door, rolling gate, gate, telescopic door and other control and other remote control audio fields.
