Detail Information

Product Introduction

 

The SMT1005 is a semiconductor type of sensor developed on MEMS electrodes for ethanol measurement. It encapsulation by TO46 package. When ethanol gas contacts the sensing material, the conductivity of the sensitive material will change. A simple circuit can be used to convert the change in conductivity into an electric signal corresponding to the gas concentration.

 

Main Application

 

● Alcohol monitors

● Smart phones, computers, cars and other consumer electronic products to detect ethanol content.

 

Sensor Characteristics

 

● Small in size

● Low power consumption

● High sensitivity

● Fast response and recovery time

● Simple test circuit

● Good stability and long life time
