I have this Proteco RF36 and they work very well:
HI. This is, probably, one of the most complete sliding gate opener project shared in the Internet. Thanks for sharing.
One of these days I will try it and give my feedback (no time now).
I have my arduino gate opener project and its working.
I never shared it because it's not complete and have some bugs.
My suggestions for improvements:
1- open gate from smart phone (my house is 90m from gate and RF is not enough strong ;) )
I use a simple html code to display a button but there are other ways.
2- Force sensor - I don't know the best way to do it but maybe with a amp meter (like sct013, links above)
I think the motor will consume more energy if stuck.
I don't know if it has the precision needed... it needs to be tested
