Description:
The DFRobot Gravity PH3 Sensor (Calibrated) offers a high-performance solution for detecting phosphine (PH3) concentration in a wide range of environments. Utilizing a stable and sensitive electrochemical sensing principle, this probe demonstrates strong resistance to interference and provides accurate measurements with a service life of up to two years. Its factory calibration ensures out-of-the-box functionality for rapid deployment in portable gas detectors, air quality monitoring systems, industrial safety setups, mines, and storage facilities where air circulation is limited. The sensor's versatility is evident in its three output modes: analog, I2C (with 32 adjustable addresses), and UART (enabling reliable serial communication with parallel-to-serial and serial-to-parallel data conversion and parity checking). Furthermore, an integrated temperature compensation algorithm guarantees measurement accuracy under fluctuating temperatures, and a programmable threshold alarm adds an extra layer of safety and control. Its compatibility with mainstream platforms like Arduino, ESP32, and Raspberry Pi, facilitated by the intuitive Gravity interface and comprehensive sample code, simplifies the creation of sophisticated phosphine detection systems.
