Product Introduction

 

  The SMD1013B air quality sensor (TVOC) is a miniature gas sensor developed based on MEMS semiconductor materials and can be used to detect TVOC gas content in different scenarios. The sensor is a VOC gas sensitive material and sensor electrodes are developed independently. When organic volatile gas contacts the sensing material, the conductivity of the material will change. A specific test circuit can be used to convert the change into an output voltage signal corresponding to the gas concentration.
