Overview

The PS1-VOC-10-MOD-I2C is a solid polymer electrochemical sensor module designed for detecting Volatile Organic Compounds (VOCs) within a range of 0-10 mg/m3 or ppm. It provides a digital output via I2C and UART interfaces, simplifying integration by handling the complex analog-to-digital conversion and calibration internally. The module supports both active upload and question-and-answer communication modes for flexible data retrieval.

Why Choose This Part

This module offers high resolution with 8-bit digital output and eliminates the need for external signal conditioning circuitry. Its dual-interface design (I2C and UART) provides compatibility with both low-power microcontrollers and industrial gateways.

Applications

Indoor Air Quality Monitoring
Integration into smart home systems to detect off-gassing from furniture, paints, and cleaning agents.
Industrial Safety Systems
Monitoring workplace exposure limits for hazardous organic vapors in manufacturing environments.
HVAC Control
Demand-controlled ventilation based on real-time VOC levels to optimize energy efficiency and occupant health.

Key Specifications

Type Volatile Organic Compound (VOC)
Output I2C

Getting Started

Connect the module to an I2C master device and pull up the SDA and SCL lines to the system logic voltage. Use the question-and-answer mode to poll for gas concentration data or configure the active upload mode for periodic updates. Ensure the sensor has adequate airflow and is calibrated according to the manufacturer's drift specifications.
