long range remote control
« on: October 24, 2009, 04:36:42 AM »
Hi, I've seen a remote control used for cranes.
Could you teach me how they works? I believe there are lots of different method doing this.
I want to know the principle of how this works, because, I want to make something phisically happen remotelyby controlling such remote controls like a microcontroller.
hopefully, I want to have 100m range even in the complex buildings.
Car's door lock system mechanism is just what I need. I hope to have longer control range than such car door lock system.

First hit on google for "long range RF"

http://www.linxtechnologies.com/Products/RF-Modules/LR-Series-Long-Range-Wireless-Communication-Modules/

Works 2000 to 3000 feet. 

Incorporate that into some circuit that controls a solenoid to unlock and lock your car door and you should be good.

Basically, just look for some long range RF chips.

Hi, thank you very much for letting know that.
3000feet control range is just what I need.
Hopefully, I want to flash some LED before controlling solenoids.
When a button(like this one http://www.eleparts.co.kr/pdf/jps2285.pdf) on the transmitter is pushed, I need LEDs on the receiver to be flashed. Could you advise me how to set up such functionality using the RF modules like the one you mentioned? http://www.linxtechnologies.com/Products/RF-Modules/LR-Series-Long-Range-Wireless-Communication-Modules/
I've seen the module data guide of both transmitter and receiver but frankly, I need more help and advise to simplify the circuit for only the functionality I mentioned.
