It is an industrial component with optical sensor and movement sensing for welding helmet automatic shutter control; features built in charge pump for single 3v battery operation
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. Internal charge pump supports operation from a single 3V battery.
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. To support ‘analog’ style input via potentiometers, a low power time multiplexed hardware controlled ADC is included.
