AM7P air quality monitor product view

AM7P is a 7-in-1 modular indoor air quality monitoring solution developed by Beijing Weesky Electronic Technology Co., Ltd. It combines laser-scattering, electrochemical, and NDIR infrared sensors to monitor PM2.5, formaldehyde, TVOC, CO₂, temperature, and humidity in real time. Check readings and control the device through the official WeChat service account.

Key features​

  • Exclusive AutoSense + V4 DART module: Every DART formaldehyde probe fitted with a V4 module is rigorously tested in the laboratory. Weesky's AutoSense technology automatically matches probe sensitivity to help the probe deliver its best formaldehyde detection performance. The V4 module integrates AutoSense, automatic compensation, and candlelight-noise suppression. It provides ripple stability below 150 μV, a 12-bit ADC, and formaldehyde resolution down to 0.004 mg/m³.
  • Fully open sensor architecture: The design avoids an enclosed probe and compensation-only approach, keeping airflow smooth and temperature/humidity readings more representative. Sensors are hot-swappable and replaceable, with an average service life of 3–5 years.
  • Transparent ranges and accuracy: All seven channels specify their range, resolution, and error, with comparison records against professional instruments. See Ranges and Accuracy.
