WZ-H3-NK

Component

HCHO sensorFormaldehyde moduleMicro fuel cellUART0–1 ppmHigh-temperature resistant

WZ-H3-NK is a pre-calibrated UART formaldehyde module for 0–1 ppm HCHO measurement in environments up to 70 °C.

Best for

  • Indoor HCHO monitoring
  • Vehicle cabin air applications
  • Air-conditioning and air-purifier equipment

Avoid if

  • Industrial safety instrumentation
  • Personal exposure monitoring
  • Applications requiring documented compliance status

Check before use

  • Confirm UART TXD/RXD integration and checksum handling
  • Confirm exposure conditions are within -40 °C to 70 °C and 10–90% RH non-condensing
  • Confirm mechanical mounting and environmental protection
