DFRobot Gravity Analog pH Sensor

Added to your shopping cart

DFRobot Gravity Analog pH Sensor is specifically designed to measure the pH of the solution and reflect the acidity or alkalinity. This secondary generation pH meter pro sensor is an upgraded version of the pH meter pro V1 that greatly improves the precision and user experience. The onboard voltage regulator chip supports the wide voltage supply range of 3.3V to 5.5V, which is compatible with 5V and 3.3V main control board. The gravity analog pH sensor is used in various applications such as aquaponics, aquaculture, and environmental water testing.
