The relationship between the sensor output and water quality is non-linear but predictable.
With an operating range of , YL105 tubing performs reliably in both freezing outdoor conditions and high‑temperature engine compartments. yl105 datasheet
While the YL105 is efficient, at maximum current loads, it requires adequate copper pour on the PCB to act as a heatsink. The relationship between the sensor output and water
When using this board with a microcontroller like an Arduino, the connection logic is as follows: Description Power Input Connect to (the regulator handles the drop to 3.3V). Connect to common ground. Chip Enable Digital pin used to control RX/TX modes. Chip Select Not SPI Select pin (active low). Serial Clock Connect to hardware SPI clock pin. Master Out Slave In Connect to hardware SPI MOSI pin. Master In Slave Out Connect to hardware SPI MISO pin. Interrupt Request Optional pin for handling packet arrival. Usage Note While the YL-105 handles the power supply When using this board with a microcontroller like
Data line. Connect to SPI MOSI (e.g., Pin 11 on Arduino Uno).
The tubing withstands extreme temperature fluctuations, mechanical abuse, and chemical exposure in railway rolling stock, manufacturing plants, and outdoor substations.
