Cellular Triple Temperature Sensor – Battery Powered, 3×Sensors

The Battery-Powered NB-IoT / LTE-M Triple Temperature Sensor (D23-Cellular Version) is designed for long-range, long-life temperature monitoring across industrial, agricultural, and environmental applications. Using Australia’s NB-IoT and LTE-M (Cat-M1) cellular networks, it operates reliably in remote areas without Wi-Fi or LoRaWAN gateways.

This model features three independent DS18B20 stainless-steel waterproof temperature probes, each capable of measuring –55°C to +125°C with ±0.5°C typical accuracy. With triple-point sensing, it is ideal for:

• Soil temperature at three depths

• Compost core / mid / outer temperature profiling

• HVAC supply / mid / return pipes

• Multi-zone cool rooms or freezers

• Inlet / mid / outlet process lines

• Tank top / middle / bottom temperature

• Multi-point water, pipework & bore sensing

• Environmental & agricultural monitoring

Powered by a long-life 8500mAh Li-SOCl₂ industrial battery, the device achieves multi-year autonomous operation depending on reporting intervals — perfect for remote, hard-to-access sites.

The rugged IP66-rated enclosure protects the device from dust, rain, UV, and harsh Australian outdoor conditions.

The sensor supports temperature alarms, BLE configuration, OTA firmware updates, and internal data logging, ensuring no readings are lost even during temporary network outages.

It integrates seamlessly with ProSight Monitoring Software for dashboards, alerts, histories, and multi-site visibility — or can be connected to custom IoT and SCADA systems using MQTT, HTTP, or UDP payloads.

ProSense stocks this unit in Australia, offering fast delivery and full local technical support.
