SPI clock line driven by the master microcontroller. yl105 datasheet better
is a dedicated adapter board designed to simplify the use of wireless modules with 5V microcontrollers like the Arduino Uno
The datasheet specifies ±0.2°C temperature accuracy and 0.1°C resolution, which is essential because chlorine readings vary significantly with temperature.
Alpha Wire's F221 series YL105 heat shrink tubing delivers superior environmental protection with cross-linked polyolefin construction. SPI Select pin
Before powering up the SRWQ100-YL-105, the datasheet warns: the membrane head is fragile and cannot be repaired once damaged. New sensors must undergo polarization for at least six hours before use. If no electrolyte remains in the membrane, measurements will be inaccurate or fluctuate.
For the chlorine sensor, the user manual emphasizes cleaning and calibrating the membrane head timely—dirt, adhesive, or encrustation cause inaccurate measurements. Zero oxygen or air checks must not exceed specified values.
