DT311 Temperature and Humidity Sensor
Wireless temperature and humidity monitoring for rooms, cabinets, and facilities
DT311 measures ambient temperature and humidity and sends data to the cloud through NB-IoT, LoRaWAN, or Sigfox. It is designed for protected indoor environments where operators need remote environmental visibility, alarm indication, and flexible integration.
Customer Value
Environmental data that can be used by facility teams and IoT platforms
Accurate ambient monitoring
Measure temperature with +/-0.3 Celsius accuracy and humidity with +/-2% RH accuracy for rooms, cabinets, storage spaces, and protected facilities.
Multiple wireless options
NB-IoT, LoRaWAN, and Sigfox versions help projects match local network coverage and platform architecture.
LED status indication
Built-in LEDs indicate charging status and alarm states, helping maintenance staff understand device condition on site.
Battery or DC power
Use the internal rechargeable lithium battery for flexible placement or DC power where permanent monitoring is required.
Open protocol
Dingtek supports protocol review and data parsing for customer platforms after project confirmation.
Remote monitoring
Environmental data can be monitored through Dingtek cloud workflows or integrated into customer dashboards and alert systems.
Applications
Suitable for protected spaces that need remote environmental supervision
DT311 is a compact choice for projects that need wireless temperature and humidity visibility without complex cabling. It supports facility operation, storage monitoring, greenhouse rooms, equipment cabinets, and industrial rooms.
Project note: DT311 is suitable for indoor or protected deployments. For outdoor exposure, condensation, high dust, or special enclosure requirements, confirm the installation environment before procurement.
