I am looking for a way to receive data from my electric car when it is charging.
The distance from the car to the receiver is about 30meters, so i was looking at some cheap RF module that could set up a wireless connection, perhaps with a 100m range. Speed is not important. 2400-9600bps would work just fine.
I know the Xbee is the right solution, but it turns out a bit pricey for what it is, given that i need 2 units. Any sugestions?
