“You can get this Radio Frequency 315/433 MHz Transmitter-receiver Module easily from the electronic shop. we can use this mini transceiver module for many applications in our daily life like to make a remote control for cars, we can control or operate a Relay using this awesome module, think and use this module for your own wish but dont forget the maximum range of this module is only up to 90m you can extend this range by do a little trick with the antenna structure but i think 90m is enough .”
