Decode and send 433 mhz rf signals with arduino posted by gnd to vcc april 26 2020 july 17 2020 posted in uncategorized this guide shows how to use an arduino to decode 433 mhz signals from rf remotes and send them with an arduino and a 433 mhz transmitter to remotely control mains switches outlets.
Using a 17 2 cm antenna on the 433 mhz transmitter makes coding the key fobs quite a lot simpler. Especially if one makes the number of sequence repetitions large i e. Change num attempts from 10 to 100.
There are many different codes possible already with this 25 bit sequence but if one imagines that the number of bits the high time. Bei 40 mhz müssen die beiden sender etwas entfernt voneinander gehalten werden. Bei 433 mhz sendefrequenz müssen sich die beiden sender beim einlernen berühren.
Bei 868 mhz sollte der abstand zwischen den sendern beim einlernen maximal 5 cm betragen. Sie sollten sich auch nicht direkt berühren. In europe the most common frequency these devices use is 433 92 mhz which is usually referred as 433 mhz and sometimes 434 mhz.
There are two other frequencies typically used 433 42 mhz and 868 3 mhz. In the us 915 mhz is typical for more precise definitions see itu and search for your country. Programmering af sendere med 433 92 mhz.
