Gravity: PH3 Sensor (Calibrated) - I2C & UART

This sensor efficiently detects phosphine concentrations with remarkable precision, featuring triple output modes: analog, I2C, and UART. Its factory-calibrated probe ensures accurate measurements across various environments, particularly beneficial in fields like industry, mining, and environmental protection. This versatile device can seamlessly integrate into different settings for continuous monitoring, providing reliable and timely data.

The probe's electrochemical principle offers robust anti-interference capabilities, alongside high sensitivity and stability. Its service life extends up to two years, making it both a durable and cost-effective solution. With 32 modifiable I2C addresses, an integrated temperature compensation algorithm, and a threshold alarm function, it allows for seamless compatibility with popular main control boards such as Arduino, ESP32, and Raspberry Pi.

The sensor includes an intuitive Gravity interface and complementary sample code, enabling users to quickly assemble a phosphine detector. Part of a broader series by DFRobot, it accompanies a suite of 12 gas detection sensors including CO, O2, NH3, and more. These follow consistent usage patterns and data formats, allowing for easy combination to suit specific monitoring needs.
