Description: Sold as a receiver only. This receiver type is good for data rates up to 4800bps and will only work with the 434MHz transmitter. Multiple 434MHz receivers can listen to one 434MHz transmitter.
This wireless data is the easiest to use, lowest cost RF link we have ever seen! Use these components to transmit position data, temperature data, even current program register values wirelessly to the receiver. These modules have up to 500 ft range in open space. The receiver is operated at 5V.
We have used these modules extensively and have been very impressed with their ease of use and direct interface to an MCU. The theory of operation is very simple. What the transmitter 'sees' on its data pin is what the receiver outputs on its data pin. If you can configure the UART module on a PIC, you have an instant wireless data connection. Data rates are limited to 4800bps. The typical range is 500ft for open area.
This receiver has a sensitivity of 3uV. It operates from 4.5 to 5.5 volts-DC and has digital output. The typical sensitivity is -103dbm and the typical current consumption is 3.5mA for 5V operation voltage.
Features:
- 434 MHz Operation
- 500 Ft. Range - Dependent on Transmitter Power Supply
- 4800 bps transfer rate
- Low cost
- Extremely small and light weight

Operational Tips
It is recommended that the following is done to ensure sensible tx/rx of data :
- All packets of data should be sent Manchester Encoded
- Packets should use some initial 'Sync Words' to 'wake-up' the RF TX and RX gain levels.
