Transmitter Specifications 433 MHz RF transmitter Some of the specifications of the transmitter and receiver modules are listed below. This low power consumption makes them very useful in battery-based implementations.

These modules are ASK (Amplitude Shift Keying) or OOK (Of Hook Keying) type RF modules, that means they usually draw no power when transmitting a Logic “zero” and as such consumes a significantly low amount of power. They are used in all forms of short-range, simplex-based communication between two microcontrollers with one of the microcontroller serving as the transmitter while the other serves as the receiver. These modules are very popular among makers and DIY enthusiasts due to their low cost and ease of use. The 433 MHz Transmitter and Receiver Modules 433 MHz RF Transmitter and Receiver Module For today’s tutorial, we will look at how to use these modules to establish communication between two Arduino boards. For short range, low-budget communication between two microcontrollers, one of the most preferred medium used is Radio Frequency (RF) communication using the 433MHz RF transmitter and receiver modules. Several options exist for implementing any of the two communication modes mentioned above and the selection of a particular option, usually depends on the specification of the project, especially the distance between the devices and cost.

While building microcontroller based projects, there are occasions where communication will be required between two devices, either in a duplex/transceiver based operation (where both devices can transmit and receive at the same time) or in a simplex-based operation where communication is one way (Receiving device cannot transmit and the transmitting device cannot receive).
