Description

  • DFRobot Gravity PH3 Sensor (Calibrated) - I2C & UART
  • Offers high stability and high sensitivity
  • Detects Phosphine (PH3) gas
  • Strong anti-interference ability
  • Supports three output modes analog, I2C, and UART
  • Working Voltage: 3.3 ~ 5.5 V DC

The DFRobot Gravity PH3 Sensor (Calibrated) - I2C & UART 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. Can be widely used in the detection of phosphine in industrial and environmental protection fields.

The probe adopts the electrochemical principle, has the characteristics of strong anti-interference ability, high stability, high sensitivity, etc., and the service life is as long as two years.
