Parameters of transmitter Actual working distance: 50-100 meters Working voltage: 3-12V Working current: 10-15mA Work: AM Transmission rate: 4KB / S Transmitting power: 10mW External antenna: 28cm ordinary multi-core or single core Pin arrangement from left to right: (DATA, VCC, GND) Size: 1.9CM * 1.9CM * 0.9CM Parameters of receiver Length:27mm Outer diameter:5.4mm Cable diameter:0.5mm Spring length:20mm Welding feet:4.0mm Note:VCC voltage should be consistent with the module operating voltage, and to do the power green wave stably, the antenna position have influences on the effect of module receiving,when installation, the antenna should be as far as possible to be vertical, away from the shield, high pressure and interference sources; When receiving frequency, The module and oscillation resistance should match the emission Package included 5 x Transmitter module 5 x receiver module 10 x Helical antenna

Transmitters did not work, receivers unreliable
The receivers were not entirely reliable, if I held down an button to send an RF signal some of the channel numbers it gave were incorrect. Also unfortunately I could not get any of the transmitters to work after many hours of attempts before I gave up and bought some more elsewhere (transmitters from another brand worked so I know it was an issue with them).
