Electronics Newbee - Need Advice on Receivers

[ricardof]

Hello,

I am trying to get the correct electronics (Receiver, Remote Transmitter & Battery) for a project that I am trying to personally built myself as a hobby. I have no electronics background at all thus I am hoping everyone here can help. Below are my questions and a picture of what the electronics currently look like.

Actuator = For my project the actuator is just a Car Trunk Latch. The basic function of the latch is just to open with a press of a button (from the transmitter) similar to what a remote control car key would do.

Receivers - I have been having problems buying the correct receiver. Almost all receivers I have purchase send out a constant signal to the Actuator that need to be turned off by the Transmitter. Thus instead of pressing the transmitter button 1x and sending out a quick signal to open up the Latch and then turning off. The Receiver I have purchased keep a constant transmission which I need to turn off (not ideal).

If someone can tell me how to identify a Receiver that send out a constant signal vs. one that send out a 1x signal and then turns off that would be extremely helpful and save me lots of time and money buy and tying out different receivers. The only receiver I have found to work the way I want are Keyless Car door receivers.

Transmitter = In an ideal world I would like a transmitter that is capable of controlling two different Receiver. For example the Transmitter would have two button A & B that would control two different transmitter A & B. The idea is to put 2 independent latch system, but be able to control both of them with one single transmitter(remote)

Battery = All the electronic here is based on a 12V battery system. I have tried 2 different types of batteries with moderate success. 1) 12v Lead Acid Battery 0.8amp & 2) Tenergy Lio-Ion 11.2V 2200amp Battery. In my test both type of battery have experience short life cycle (less then 6 months).

Thanks for any insight or suggestion you may have to make my project run better.

Hi ricardof,

You could probably use a SeedStudio 2-Channel 315MHz Wireless Relay Switch for your application.
It is not a Plug & Play system like you did use in the past but might work better for your needs.

Other than that, you could make your own with an Arduino, relays and remote but that will require programming.

All the best,

As I understand the receiver runs your actuator continuously unless the transmitter sends a second signal to stop the actuator. For your receiver you could add a timer that will stop when the actuator reach its full cycle. In this case you do not have do push the transmitter’s button twice. You could check on 555IC timer simple projects for this. And for the transmitter you can operate two systems with two different operating frequencies.
