Antenna: Onboard 315MHz dedicated PCB Antenna.įor today’s tutorial, we will demonstrate how to use these modules by creating a simple sketch to send messages between two Arduino fitted with these modules.To increase transmit range, you can increase the power to the transmitted up to 12V DC. Transmission distance: When supply power is 5V, the open area transmission distance is around 150 meters.Some of the specifications of the long-range RF Modules are highlighted below: For instance, when VCC is 5v, the modules are able to reach 150m range in open space, as such, the range can be improved further by increasing the supply voltage. The attainable transmitting power of the modules depends on the voltage applied at it’s VCC pin. The new transceivers work the same way as the cheaper modules, maintaining the same pin configuration/layout, support the same libraries (like the VirtualWire library for Arduino) but the new modules, however, have a greater power output and a solid, convenient PCB antenna which increases range while also keeping things neat. To solve this and give makers more option and value, PMD Way developed these new 315/415 Mhz transceivers. Short-range RF Transceivers like the 433MHz transmitters discussed in one of our previous post are very popular among DIY hobbyist and makers, however, their short-range was a bottleneck for users as they barely offer signal coverage for an area bigger than a standard room.
