Gravity PH3 Phosphine Sensor I2C and UART

The Gravity PH3 Phosphine Sensor from DFRobot is a highly advanced, factory-calibrated sensor, specifically designed for measuring phosphine concentrations (PH3) in the air. With an impressive measurement range from 0 to 1000 ppm and the ability to communicate through analog, I2C, and UART output modes, this sensor provides a comprehensive solution for a variety of applications, from industrial monitoring to environmental protection projects. The electrochemical measurement method ensures high accuracy, stability, and excellent resistance to interference. An integrated temperature compensation and an alarm function for threshold values further increase the reliability of the sensor. Thanks to its compatibility with common microcontrollers like Arduino, ESP32, and Raspberry Pi, the sensor can be easily integrated into existing systems.
