Thermal runaway smoke sensor FS02209

  • Fast warm-up time
  • Long lifespan.
  • Short start-up time

Thermal runaway smoke sensor FS02209 Introduction

This solution is capable of effectively monitoring the concentration of dust, temperature and other indicators released prior to triggering thermal runaway of batteries, and transmitting the measurement signals to the Battery Management System (BMS) through CAN communication. This approach features accurate measurement, fast response time, low cross-interference, low power consumption, long service life, and high reliability.

Thermal runaway smoke sensor FS02209 Features

This device can achieve an external interface for simultaneously and continuously measuring particle matter and temperature, while automatically completing temperature and pressure compensation.


The device has a short start-up time, fast warm-up time, and long lifespan.


It is designed in a modular way and has both digital and analog signal output functions, making it easy to integrate and control.


The device has high accuracy and repeatability, fast response time, up to 170ms.
