Indoor Air Quality RN400-T2PM-RG23

Inquiry Catalog


RN400-T2PM-RG23 is designed to measure indoor air quality. It uses the laser scattered technology to get the PM information , NDIR and MEMS technology for CO2 and TVOC. All the IAQ information are transferred to the destination cia WiFi connection. The destination would be an information system such as public cloud, local server and even PC. For high level security, it supports up to WPA2-Enterprise protocol. Premium RN400 T2 series have IP65 for protection, OLED screen for cold outdoor, F-RAM memory for instant backup and micro-SD card for CSV backup.




Communication Method

  • 2.4GHz IEEE 802.11b/g/n up to WPA2-Enterprise
  • HTTP Get/Post (Radionode V2 protocol)
