These modules are sourced from China and can be bougth via ebay.
Finally they will be used as a cheap replacement for RFM12 to switch radio outlets. For details see Issue 284 on Github.
Technical Specifications
- Receiver module parameters
- Product Model: MX-05V
- Operating voltage: DC5V
- Quiescent Current: 4mA
- Receiving frequency: 433.92MHZ
- Receiver sensitivity: -105DB
- Size: 30 * 14 * 7mm
- External antenna: 32CM single core wire, wound into a spiral
- Transmitter module parameters
- Product Model: MX-FS-03V
- Launch distance: 20-200 meters (different voltage, different results)
- Operating voltage: 3.5-12V
- Dimensions: 19 * 19mm
- Operating mode: AM
- Transfer rate: 4KB/s
- Transmitting power: 10mW
- Transmitting frequency: 433M
- An external antenna: 25cm ordinary multi-core or single-core line
- Pinout from left → right: (DATA; VCC; GND)
Remark
- VCC voltage module operating voltage and good power filtering;
- Great influence on the antenna module reception, preferably connected to the 1/4 wavelength of the antenna, typically 50 ohm single conductor, the length of the antenna 433M of about 17cm;
- Antenna position has also affected the reception of the module, the installation, the antenna as possible straight away from the shield, high pressure, and interference source; frequency used to receive, decode and oscillation resistor should match with the transmitter.
