  • Low power consumption
  • Long service life

Battery leakage monitoring sensor FS02213 Introduction

The FS02213 battery leakage monitoring sensor is a specialized and miniaturized module. It uses a self-developed MEMS production line to detect the gas produced by battery liquid volatilization and battery combustion with a metal oxide semiconductor (MOX) sensor, which has good gas selectivity and stability. The sensor also includes a built-in temperature sensor for temperature compensation, as well as special anti-interference design. With high data acquisition accuracy and serial data output interface, the FS02213 combines mature semiconductor detection technology with sophisticated circuit design to create a dedicated gas sensing module.
