Gravity: PH3 Phosphine Gas Sensor (Calibrated, I2C & UART, 0-1000ppm)

The Gravity PH3 Phosphine Gas Sensor is a factory-calibrated electrochemical detection module designed for measuring phosphine concentrations from 0 to 1000 ppm. With support for I2C, UART, and analog interfaces, it is ideal for makers, researchers, and engineers building industrial safety and environmental monitoring systems.

Electrochemical detection technology

The module uses an electrochemical sensing element to detect phosphine (PH3) gas concentrations reliably. It delivers stable performance tailored for targeted gas monitoring tasks.

Factory-calibrated precision

Each unit comes pre-calibrated directly from the factory to streamline deployment. This allows you to collect accurate gas concentration data without needing complex on-site calibration setup.

Wide 0 to 1000 ppm range

The sensor measures PH3 gas concentrations across a broad range of 0 to 1000 ppm. This makes it suitable for detecting both baseline exposure levels and significant gas accumulations.

Flexible output interfaces

Equipped with I2C, UART, and analog communication options, the sensor integrates seamlessly with a wide variety of microcontrollers and data acquisition platforms. You can select the interface that best matches your project architecture.
