This cost-effective 433MHz wireless relay switch circuit allows remote relay control using an RF transmitter and receiver module. It is ideal for scenarios where wired connections are impractical or ...

Why another home automation system for Raspberry Pi? There are lots out there already - some are quite hacky with wires branching out to breadboards or Arduinos, some are neatly done but took strange ...

The development was done on an Arduino Due. Tests have shown that the working range of several 433Mhz receiver modules strongly depend on the quality of the power supply. When the Arduino Due is ...

Remote control based on cheap keyfob modules. Use the buttons as bits to encode up to 15 individual channels. Costs: €5! I was playing around with some 433MHz wireless modules which are sold all ...

These days, 433-MHz RF transmitter/receiver modules are very popular with electronics hobbyists and tinkerers. These cheap short-range radio modules can be used with almost all microcontrollers for a ...

With this circuit, a single transmitter and simple set of user pushbuttons can initiate one of four different outputs, two at each of two remote receivers with very different applications. The ...
