Gas Sensors

HCHO sensorformaldehyde modulemicro fuel cellUART0 to 1 ppmhigh temperature resistant

WZ-H3-N is a factory-calibrated UART formaldehyde sensor module for 0 to 1 ppm HCHO measurement, including operation in elevated-temperature environments up to 70 °C.

Best for

  • HCHO monitoring in vehicle cabins
  • air-conditioning and air-purifier monitoring
  • smart-home and portable formaldehyde monitors

Avoid if

  • Applications requiring a stated compliance declaration
  • Exposure to organic solvents or persistent high gas concentrations
  • Systems needing a range above 1 ppm for normal measurement

Check before use

  • Validate response and accuracy at actual operating temperature and humidity
  • Confirm UART packet parsing and active-upload versus Q&A mode
  • Verify mounting dimensions and connector orientation
