Gravity: Analog pH Sensor V2

SKU: SEN0161-V2

Gravity: Analog pH Sensor V2 is designed for precise measurement of solution pH, reflecting its acidity or alkalinity, and is ideal for applications like aquaponics, aquaculture, and environmental water testing. This upgraded version offers improved precision and user experience, featuring an onboard voltage regulator chip for wide voltage supply compatibility, hardware-filtered output signal with low jitter, and a software library using a two-point calibration method that automatically identifies standard buffer solutions. This product is easy to implement with a main control board and software library, requiring no soldering or modifications.
