Hello!
I'm building a RF(434Mhz) based temperature station, in which I have multiple transmitters around my house sending temperatures, every 5-10 seconds.
I most likely power them off the wall socket.
I'm able to get some decent range with MCUs 5v supply, but I'd like to extend the range up to the 12v that the transmitter allows.
Could I use 5v to 12v boost converter to momentarily boost the voltage when I send the data? Meanwhile it would refill the caps until the next sending. Would there be any sense doing so?
I'm also trying to make it cost efficent, max. 10$ per transmitter.
I'd be able to change the supply voltage to 9-12v, but that would require step-down for the MCU. I'd still like to have some room for 5V battery power option.
Bonus question:
Would there be any sense to power the RF module through Atmega output pins? In this way I'd be able to send power to the module only when I'm transmitting. So that if I accompany a boost converter, it wouldn't be hogging current all the time.
