Welding Helmet automatic shutter control with LCD display feedback

An industrial component with optical sensor and movement sensing for welding helmet automatic shutter control.

This project was an industrial grade component with built in optical welding light sensor and movement sensing for automation and control of the shutter in welding helmets.

The system includes control for high voltage generation for shutter control. A photodiode sensor with associated custom designed filters can detect the start and end of welding sessions automatically. The system includes a 16 bit processor and EEmemory to allow for the most flexible application adaptation. The system also includes an interface to control a customized LCD display for information feedback as well as a number of push button sensors for user input.

Application area:

The application area is automatic shutter control for welding helmets.

Top technical features:

• Photodiode sensor with customized frontend amplifiers

• Push button configurable sensitivity

• LCD display based feedback

• Battery operated

• 16 bit controller and eeprom memory for application customization
