I’m using some cheap 433mhz rf links and VirtualWire to create a wireless environmental logger. It’s pretty basic at the minute, I have an LDR and Temp sensor on one arduino transmitting to another arduino with an LCD attached for display.
Would it be possible to add another TX unit and have that transmit it’s own readings to the same receiver?
I’d like to have about six of these ‘sensor packs’ transmitting to one ‘master’ arduino which will hopefully log each transmitters output to a SD card.
It’s taken me a while to understand VirtualWire, and I’ve noticed no addressing structure. Could I add an ID tag at the end of each packet to differentiate between transmitters?
