Description:

​Specially designed line sensor for more broad line coverage. Each sensor is placed with 7mm apart.

Technical Specs

Works at 5V, total current draw is 240ma for all 16 sensors.

Total weight is 6 grams.

Sensivity is set by built-in trimpot at board.

XLine board's dimension is 117.8mm L x 35mm W x 4.3mm H.

Sensors selected with analog multiplexer and later compared with op-amp. At output sensor is direcly giving digital output.

You need to attach 4 digital outputs and 1 digital input.

So Xline will use total 5 I/O only except of 16!

Kit include:

1 x XLINE 16 Sensor Array Board - Digital
