Electrochemical O3 Ozone Sensor Module FS01101

  • O3 detection sensor
  • Electro-chemical sensor
  • Outstanding anti-interference
  • Temperature compensation
  • Reliable service for sustainable cooperation

Electrochemical O3 Ozone Sensor Module FS01101 Introduction

FS01101 is a fuel cell type electrochemical sensor that works by the oxidation and reduction reactions on the working electrode and counter electrode, releasing charges to form a current. The magnitude of the current generated is proportional to the concentration of ozone and follows Faraday’s law. By testing the magnitude of the current, the ozone concentration can be determined. It uses a high-stability gas sensor and a high-performance microprocessor with UART output for easy use. The module adopts precise automatic calibration and detection equipment, reducing human interference and ensuring the accuracy and consistency of data during large-scale production. This ozone sensor is very suitable for portable product applications, with a small and convenient design for integration.
