An old sliding gate got upgraded with electric motors.
This particular sliding gate is very heavy and gets opened and closed quite frequently, thus automating it certainly made life a bit easier.
Update
After 7 years of operation, this project has been reworked with a new control PCB and VFD motor control to add new features and improve performance. Check out the updated version: Automated Sliding Gate V2.
The following describes the first version of this project…
Specification
- Power supply: 230 V AC
- Control Interfaces:
- Buttons on gate
- Buttons on control box
- Remote control (radio transmitter)
- Web interface
Future Features
Note: This post describes an earlier version of the project. The strikethrough features (and more) were fully implemented in reworked version Automated Sliding Gate V2.
