I am looking for a miniature wireless transmitter and receiver. Propagation distance enough to radiate between a wall thickness.
radiation distance: 0.3-0.4 metre (30 to 40 millimetre)
The transmitter and receiver and relay possible smallest (miniature)
Operating voltage can to be 3-12 volt DC.
When the transmitter is switched on (powered 3-12vDC), At the receiver end it should just operate a miniature relay (Normally open to close)
The relay and rf receiver should be the smallest size possible.
In your Bid Please specify the transmitter and receiver (including relay dimensions –LxWxH)
Any furthur information that you require please contact me
2: 3-12 Vol DC
4: 3-12 Vol DC
5: Miniature Relay
Note: If there is a variation in cost please specify.
A power to TX is connected, - it should transmit RF waves and RX should operate  a micro relay and hold from the idle state of “NO” to “NC” until the power to TX is removed. eries for them.
Pl dont worry about the Power source for either end as I do have batt
I need the exact size (dimension) of the TX and RX along with its relay.
To me the size of TX and RX (including relay) matters. Pl let me know the size of the pcb. Please specify if your bid covers postage of the assembled PCB to Australia as well.
