Building blocks associated with Arduino 433 Mhz transmitter & receiver
Newbie here. I want to make a temperature monitor that will transmit an alert signal to a receiver. If I use the little 433Mhz Arduino RF transmitter / receiver modules, what would I need with them? I know these can be attached to the Arduino programing boards and are made functional by a computer program, but I don’t want to stick the Arduino program board & computer under the house where I want to measure the temperature. I’m confused by this. I understand these little units are used in remote control cars & planes, but what do they get connected to?
