why is my 433MHz wireless receiver outputting a 6Hz pulsating output? Answered
hello, i recently bought this receiver http://www.dinodirect.com/315MHz-433MHz-Wireless-Receiver-Board-Module-AK-R02A.html
and have tried it out with my 433MHz transmitter, and something strange happens.
im using it to light up an led, and the led is flashing at what ive calculated is about 6Hz. why is it doing this?
for some reason it ceases to do this when i hold the antenna of my transmitter within 2-3cm of where the antenna of the receiver should be (i havent added an antenna yet), and the frequency drops the further away the transmitter is, though not by much, maybe down as low as 4hz at 30M.
could this have something to do with the fact that the frequency crystal says R315A? does this mean that its 315MHz and not 433MHz like my transmitter?, i wouldn't expect it to work though, and i did order it as 433MHz or could it be just the led? i have nothing else which i can use to tell otherwise.
what i want the receiver board for is to power a relay. i haven't got the relay yet though. will this cause the relay to rapidly switch on and off?
the transmitter i am using is a standard 4 channel 433Mhz transmitter (brown wood style plastic cover) standard with any wireless modules available on eBay and receiver transmitter combos on dinodirect.
on both ebay and dinodirect, none of the sellers have a clue about where the datasheet for this is, or how they work (i doubt at dinodirect they even know what it is).
