Product Introduction
SMT-016 is a semiconductor type gas sensor designed to detect liquefied natural gas components. The conductivity of the sensing material changes with the concentration of the target gas. A simple circuit can be used to convert the change in conductivity into an output signal corresponding to the gas concentration.
Main Application
● Civilian gas leak detector and alarm
● Portable gas detector
Sensor Characteristics
● High sensitivity
● Stable performance
● Fast response and recovery time
● Anti-interference ability
● Long life time
