What are the measuring range and accuracy?

Humidity 0-100% RH, temperature -20°C to +80°C, with ±0.2°C and ±2% RH typical accuracy. The slotted sintered probe is cable-mounted, so it can be placed inside cabinets and ducts.

Does it support threshold alarms?

Yes. High and low thresholds for both temperature and humidity are configured remotely, and the sensor pushes alerts through the cloud platform when limits are crossed.

How long does the battery last?

Designed for more than 10 years at a one-hour reporting interval under specified test conditions; actual life varies with network coverage, temperature, and reporting frequency. No mains wiring is needed at the installation point.

Which wireless networks are supported?

4G and NB-IoT with MQTT uplink to Hitelecom Cloud, a customer cloud, or private deployment. LoRa is available for multi-sensor sites with a private gateway.
