PS1-VOC-200
Overview
The PS1-VOC-200 is a high-sensitivity electrochemical sensor designed for detecting Volatile Organic Compounds (VOCs) in a range of 0-200ppm. It utilizes a three-electrode amperometric architecture that offers a fast response time and stable performance without the risk of electrolyte leakage. This sensor is individually calibrated and provided with a test report to ensure measurement accuracy within 1 percent.
Why Choose This Part
The sensor features a small 11.5mm footprint and an ultra-low power amperometric design, making it ideal for battery-operated devices. It provides high resolution and sensitivity (55 nA/ppm) while maintaining stability across a broad pressure range of 800 mbar to 1.2 bar. The leak-proof solid polymer electrolyte design eliminates common failure modes found in traditional liquid electrochemical sensors.
Applications
Key Specifications
Getting Started
To interface with the PS1-VOC-200, use a high-precision potentiostat circuit or a specialized transimpedance amplifier to convert the nano-ampere current output into a voltage for a 16-bit ADC. Engineers should refer to the individual calibration report for specific sensitivity coefficients to implement accurate software-side compensation. Ensure the PCB design provides adequate ventilation for the 3-pin package while protecting the sensitive analog traces from EMI.
