FIGARO TGS2620 Analog MOX Gas Sensor for Alcohol & Organic Solvent Detection

规格

Product Introduction

The sensitive element consists of an integrated heater and a metal oxide semiconductor structure on an alumina substrate.Okay. When a gas is detected in the air, the higher the concentration of that gas, the greater the sensor’s electrical conductivity.
The readings will also be higher. By using simple circuits, the changes in electrical conductivity can be converted into information about the gas in question.Signal output corresponding to the concentration.The TGS2620 is highly sensitive to organic solvents and other volatile gases. It is suitable for use.For use with organic solvent gas detectors. Due to the small size of the sensitive element, the TGS2620 requires heating.The device’s current requirement is only 42mA, and the housing features a standard TO-5 metal package.
