How do I get an RF signal?

As the RF waves move away from the transmitting antenna they move towards another antenna attached to the receiver, which is the final component in the wireless medium. The receiver takes the signal that it received from the antenna and translates the modulated signals and passes them on to be processed.

Can a 433mhz receiver be used with any transmitter?

The receiver stands in front of a speaker and a subwoofer, I turn those off when I test. The 433MHz modules came in pairs. I did not respect this and use any receiver with any transmitter, wonder if this is a problem. My end-goal is 3 transmitters on one receiver. Since I have multiple Tx/Rx modules, I swapped them to exclude DOA modules.

Can you use a 433 MHz remote control with an Arduino?

If you want to use 433 MHz remote controls to communicate with your Arduino, follow this tutorial: Decode and Send 433 MHz RF Signals with Arduino. If you are an Arduino beginner, we recommend following our Arduino Mini Course .

Why does Nexa not work at 433mhz range?

Blast at them with a transmitter at close range for a while and they will become worse at picking out the signs, from the noise at long range for some time. This appears to be true of the 433Mhz Nexa devices too. When starting to transmit from further away, it may take longer before the receiver figures out it’s found a signal.

How big is a 433mhz range coil?

There’s about 21 windings, with 5mm diameter, so that makes roughly 5mm * 3.14 (=Pi) * 21 = 33 cm of wire in the coil. The 433mhz modules can be sensible on the power lines, place a cap on the power input.
