2 set module RF 433mhz interfere each other
Posted: Fri Jun 01, 2012 2:59 amhi, need help. i have 2 circuit. 2set of tx & rx 433mhz
circuit 1: sensor -> pt2262 -> Tx1=433mhz --------- Rx1 -> pt2272 -> led1
circuit 2: switch -> pt2262 -> Tx2=433mhz --------- Rx2 -> pt2272 -> led2
when the sensor ON, led1 will ON. but the prob is when the switch is ON at that time it will turn OFF the led1 and supposedly led2 must be ON but sadly it not turn ON. and vice versa.
eventhough i had set diff code of address between this two cct.
it work well if only one circuit ON that time.
How to solve this?? please help me.
my classmate also use the same module. im afraid during presentation of fyp it will interfere my project.
