My brother broke his LCD display on his saw, it is a simple display put on conductive silicon strip showing numbers and some status icons.

They priced the replacement for about 500$, which is kind of lot in our country.

So i thought that since the only important function is to measure length, that i take the sensor connected to the display, find the documentation and use it with arduino. But the documentation cant be found because it is custom made sensor by the company. It has five wires and the display was powered by one AAA battery.

Before i dive into debugging with logic probe, did anyone used that sensor in his project?

Thanks, im also uploading images of sensor and PCB.

Sensor Label of display PCB

  • \$\begingroup\$ Is replacing the LCD an option? I think you'll find that the PCB is feeding out signals to the sensor otherwise it wouldn't need so many wire cores. \$\endgroup\$ – Transistor Jun 15 '17 at 19:50

    \$\begingroup\$ You might be able to find a compatible display on eBay. The sensor appears to be a magnetic type- it may have a quadrature ~ 1V sinusoidal (analog-ish) output. Or not. \$\endgroup\$ – Spehro Pefhany Jun 15 '17 at 20:11
  • \$\begingroup\$ This may be of help. It seems like the "LS100" is pretty similar to what you have. And, indeed, it has quadrature 1Vss sinusodial output. \$\endgroup\$ – JimmyB Jun 16 '17 at 12:18
  • \$\begingroup\$ Is there any other labelling on the sensor itself? \$\endgroup\$ – JimmyB Jun 16 '17 at 12:40
