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.

Data Flow

From sensor data to cloud application

DT311 sensor

Measures ambient temperature and humidity and indicates local alarm state through LEDs.

Network access

NB-IoT connects through operator network; LoRaWAN connects through gateway infrastructure.

Cloud server

Data can be stored, visualized, and used for alerts, reports, or maintenance workflows.

Application

Use Dingtek platform workflows or integrate sensor data into customer applications.

Platform Ready

Remote dashboard and integration support

DT311 can be used with Dingtek cloud monitoring or project-specific application integration. The product supports open protocol discussion for customers that need to connect data to their own software systems.
