  • The excellent performance of the receiver module, using a digital process technology, with a strong anti-interference, stable performance, high reliability, non-directional, long life, undisturbed Japan imported chips, high stability, low power consumptionsimilar remote control does not have any interference garbled phenomenon, the transmitted signal of the wireless receiver, remote control distance, can pass through walls, no direction. Supporting the use of any of the same frequency remote control can be and market fixed code, learning code.
  • Super-regenerative receiver module LC oscillator circuit includes amplifier shaping output data signals to TTL level directly to the decoder, the use of extremely easy, and inexpensive, it is widely used. The small size, high sensitivity; frequency point debugging easy, short lead times; consistency of product quality, cost-effective, wireless remote control market, the largest amount the most widely used as a high-frequency receiver module. The receiver module has a wide receiver bandwidth, typically ± 10MHz, factory tune in 433.92MHZ DC5V power supply receiver module.

Static receiver module operating current of 4mA, the receiver module factory output noise output, if there are special requirements can be changed to the noise-free output, but will reduce receiver sensitivity.

This is a widely use module in many different application, the cost is very low and easy to use. You have to use the MCU to simulate decode and encode process as the IC PT 2262 and PT2272. The popular link is like this: MCU -> Encoder -> Transmitter —— Receiver -> Decoder -> MCU, PT2262(Encoder) and PT2272(Decoder) are optional, their existence is to 1)avoid confusing when multiple RF links in range 2) isolate disturbance. You can integrate the encoding and decoding work to the MCUs on both side. Whenever there is no 315Mhz devices around, you may use it as direct cable connection. Excuse for the documentation, we will work on them.

We tried them using the guide from Sparkfun, it’s compatible. The only difference is in package, of some excess GND pins. More over, we will make more RF modules ourselves with different frequency and capacity.

You can also order the transimitter or receiver seperatorly. TX here and RX here.

    A really useful Transmitter+Receives module set.
    I purchased several of these, and use them to communicate between Arduino microcontrollers.

    Download the “RCSwitch” library in order to be able to use them to receive RF Remote button presses, and also to simulate presses via the Transmitter.

    These are extremely useful! They run like $6 to $9 per pair anywhere else, I’m glad I came here on a suggestion from a friend!

    Those components are really easy to use.
    20-30 meters/max rate 8-10kHz (you can go to 13-14khz but you will have a bigger error rate).

    For this price, it is perfect.

    not working.

    I love these. I’m using ATtiny85 with VirtualWire library to send data.

    Be aware the receiver ramps up the “squelch”, so if you aren’t sending a signal it will increase sensitivity until you are getting static.

    Have a look here: http://www.ninjablocks.com/blogs/how-to/7501042-adding-rf-433mhz-to-your-arduino

    This is a great way to use this TX/RX.

    Using these with Manchester encoding on ATTiny85’s. They work great once you solder on an external antenna.
