DF Robot Gravity PH3 Sensor (Calibrated) – I2C & UART


This is a sensor that detects phosphine concentration and supports three output modes: analog, I2C, and UART . The probe has been calibrated at the factory, which can quickly and accurately measure the concentration of phosphine in the environment which can quickly and accurately measure the concentration of oxygen in the environment.
