Hello guys!
I want to trasmit state of three signals through RF (10m distance) - power, fault1, fault2 indicated by leds. Transmitter - powered from 12VDC, receiver - led for each signal indication, battery powered let's say CR2032, or AAA battery or some small li-po.
My initial thought was to...
Now I detect motion with my Arduino Nano and 3pin motion detector:
When detector triggers, I need to send signal (distance at least 5km) to another Arduino Nano and catch it. As far as I understand, 433Mhz is the optimal frequency for this.
Please suggest me what should I use? Which circuit...
I need Tips and recommendations on how to design a PCB with multiple RF circuits.
In my case, the PCB includes a GPS receiver, 802.15.4 2.4GHz, and 433 MHz transceivers.
I plan to use a GPS module with a patch antenna.
The 433 MHz transceivers will have a PCB or ceramic antenna. an external...
I try learning through youtube and other resources for example WiFi works on 2.4Ghz actually there are other 8 bands too (some other frequencies next/before 2.4Ghz) so different devices use those different bands/frequencies to communicate at same time, for sure on receiving end we have 8...
