Air pollutant gas sensors

We provide customized solutions for air pollutant gas sensors. Specify the gas you're interested in, and we'll provide the relevant sensor specifications. Currently, we support sensors for CO, CO2, CH4, NOx, VOx, O3, and SO2 gasses. In the AQMS1 system, a user can integrate up to three customized gas sensors.

Data logging and network connectivity:

  • Maximum logging rate: Every minute (can change depending on gas sensor’s response time)
  • Storage options: Comes with 32GB microSD card and cloud storage.
  • Backup feature: Internal data backup during cloud connectivity interruptions.
  • Internet Access: 
    • Cellular: Bring your own SIM (LTE).
    • WiFi: Requires user-provided access. Note: AQMS1 doesn't support public Wi-Fi with browser logins.
  • Always logging: AQMS1 saves data to the SD card, even offline. No internet? No problem!
  • CredoSense cloud: Use for data access, system updates, and firmware tweaks.
  • Alert System: Warnings displayed in cloud data for SD or cloud upload issues.
  • User-Friendly API: Seamlessly blend AQMS1 into your systems, no hardware fuss.

Power supply and enclousre

  • Power supply: 12v @5A DC (waterproof AC/DC adapter included)
  • Weatherproof enclosure: Protection from rain and sunlight exposure
