Today I would like to propose a simple project that requires easy skills. It’s a simple weather station, that measures, internal and external temperature. It’s made out of two components: an indoor receiver, and an outdoor transmitter. The transmission is managed at 433Mhz. The components and the electrical diagram for both devices, are showed in the video. The receiver is very easy to use. to toggle between the external and internal temperature, you need to press the button for more than 3 seconds.
