433mhz Fs1000a on 12v

Projects General Guidance

Hi

I have recently completed a project using an Arduino nano and a Fs1000a 433mhz transmitter module to control a WattsClever remote power socket. The unit works well but reliable range is limited to around the 20m mark which is a little short of where i need to get.I have experimented with aerials 165mm to 175mm long.The Fs1000a is currently running on 5v but can accept voltages up to 12v. I would like to increase the voltage to the Fs1000a to try and boost it's range but am not sure if this increase would cause trouble where my arduino data pin connects to the transmitter. I have not been able to find a data sheet on the Fs1000a so thought someone else may have come accross this and be able to help.

Thanks

I have the same transmitter/ receiver pair and I have my transmitter running off 11V and it seems to be fine.

Thanks for that I will give it a try. Did you get much of a range boost with 11v over 5v

A lot more range. I get about 90 - 110 meters in a nice open field. I'm surrounded by building where I live, but I can still get about a blocks worth of range.
