Description: These wireless receivers work with our 434MHz transmitters. They can easily fit into a breadboard and work well with microcontrollers to create a very simple wireless data link. Since these are only receivers, they will only work communicating data one-way, you would need two pairs (of different frequencies) to act as a transmitter/receiver pair.
Note: These modules are indiscriminate and will receive a fair amount of noise. Both the transmitter and receiver work at common frequencies and don’t have IDs. Therefore, a method of filtering this noise and pairing transmitter and receiver will be necessary. The example code below shows such an example for basic operation. Please refer to the example code and links below for ways to accomplish a robust wireless data link.
Based on 5 ratings:
I have 8 Ambient Weather sensors located around the house that transmit data approximately once every minute. This receiver works great at picking them all up. Highly recommend.
I used this for a weather station. With an antenna I easily get communication at 20 yards through the house and likely much further (have not tested). Extremely easy to use with the accompanying transmitter.
I rated this as excellent because for the price it is an excellent RF link. This Rx is located in my basement and receives a signal from a Tx in my garage which is approximately fifty feet away. Plus it is simple to wire and easy to program my Arduino UNO to use it.
Got these (TX and RX) for an basic wireless project, got them up and running in no time with the VirtualWire library for Arduino (http://www.airspayce.com/mikem/arduino/VirtualWire/).
