-
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!Here the test code for easy to use.//JSumo.com
