- 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.
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.
