Description

TGS1820 Hot-wire Type Semiconductor Gas Sensor

Detection Principle:

The sensitive element consists of a noble metal coil surrounded by sintered metal oxide semiconductor material. When gases are adsorbed onto the semiconductor surface, it causes a change in conductivity, which is measured as a resistance variation across the noble metal coil (coupled with the semiconductor material).

Main Features:

  • High Sensitivity & Selectivity : Exhibits prominent response while suppressing interference from other gases.
  • Low Interference from Ethanol & Hydrogen: Minimizes cross-sensitivity to ethanol and hydrogen, ensuring accurate detection.
  • Fast Response Time: Enables rapid gas concentration monitoring.
  • Compact Size: Facilitates integration into various devices (dimensions: ~φ2.9×12.35 mm).
  • Low Power Consumption: Suitable for portable applications with minimal power drain.

Detected Gas & Concentration Range:

  • Detection Range: 1–20 ppm (parts per million).

Typical Applications:

  • Detectors: For industrial safety monitoring in chemical plants or laboratories.
  • Measures human fat-burning rate and evaluates the effectiveness of ketogenic diets.
  • Assists in monitoring blood glucose levels for diabetic patients .

Dimensions:

  • Size: Approximately φ2.9 mm × 12.35 mm (diameter × length).

Driving Conditions:

  • Circuit Voltage (Vc): 2.3 V DC.
  • Heater Power (Ph): 125 mW.
