PS4-VOC-10
Overview
The PS4-VOC-10 is a high-precision electrochemical sensor designed to detect Volatile Organic Compounds (VOCs) in concentrations up to 10ppm. It features an analog current output with a sensitivity of 55 +/- 15 nA/ppm, packaged in a compact 20mm x 20mm SMD form factor for automated PCB assembly. This sensor is optimized for stable performance across a wide temperature range of -40C to 55C.
Why Choose This Part
The sensor offers a linear analog output and high resolution, making it suitable for 16-bit measurement systems requiring 1 percent accuracy. Its SMD package reduces manufacturing costs compared to traditional pin-through-hole electrochemical cells, while its broad operating temperature range ensures reliability in harsh industrial environments.
Applications
Key Specifications
Getting Started
To interface with the PS4-VOC-10, design a high-gain transimpedance amplifier (TIA) circuit to convert the nanoampere-level current output into a measurable voltage for an ADC. Ensure the PCB layout includes guarding around the high-impedance analog signal traces to maintain measurement integrity. Engineers should implement temperature compensation in software to account for sensitivity shifts across the -40C to 55C range.
