This Power density calculator allows you to measure the power density from an antenna at a certain distance by providing the output power and gain values.

Here we will learn the basics of RF module and how to use it as a standalone RF Transmitter and Receiver. Here we have explained the RF Transmitter and Receiver Circuit by controlling the LEDs wirelessly using RF.

Here is a RF Controlled robot without using any microcontroller. This robot has two parts - one is RF transmitter circuit and other is RF receiver circuit. It sends RF signals through the transmitter which are received at receiver end and robot moves accordingly in the left, right, forward and backward direction.
