Elecrow Crowtail- PH Sensor - Crowtail Interface Module

The sensor provides an analog voltage output proportional to the pH value. This signal can be connected directly to an analog input pin on an Arduino or other 5V logic microcontroller for reading and calibration against the 0-14 pH scale.

The module requires a 5V DC power supply, which is provided through the Crowtail interface. Ensure your base shield or controller can deliver a stable 5V to the connector for accurate sensor operation.

Connect the module using the included 4-pin Crowtail cable to a compatible Crowtail base shield mounted on your Arduino. The analog output pin of the sensor will map to a specific analog pin (e.g., A0) on the shield, as defined by the shield's pinout.

This composite electrode sensor is designed for measuring the pH of aqueous solutions. It is suitable for environmental monitoring, laboratory fluids, hydroponic nutrients, and other water-based samples within its 0-60°C operating temperature range.

Yes, like most pH electrodes, periodic calibration using standard buffer solutions (e.g., pH 4.0, 7.0, 10.0) is necessary for accurate readings. The glass electrode should be rinsed with distilled water after use and stored with its protective cap in place, often with a storage solution as recommended by the manufacturer.
