Detail Information

Product Introduction

 

SMT-02 is a semiconductor type gas sensor designed to detect flammable gas and smog components. The sensor gas sensing material will change accordingly with the concentration of the target gas. A simple circuit can be used to convert the change in conductivity into an output voltage signal corresponding to the gas concentration. This product has good sensitivity to propane, smoke, etc. in a wide concentration range.

 

Main Application

 

● Household gas leak alarm

● Portable gas detection instrument

● Smog and combustible gas alarm

 

Sensor Characteristics

 

● High sensitivity

● Stable performance

● Fast response and reply time

● Long life time
