โปรเจกต์ Weather station ที่เรียบง่ายและใช้งานง่ายสำหรับ Indoor และ Outdoor

The idea was to combine the 433Mhz transmission with exchange of data between two devices so a simple weather station, that measures, internal and external temperature, was the right project for me.

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.
