LoRaWAN Dual Temperature Sensor – Dual DS18B20 Waterproof Probes

The D22-LB Battery-Powered LoRaWAN Dual Temperature Sensor is engineered for industrial, agricultural, food safety, refrigeration, and environmental monitoring applications where two independent temperature points need to be measured accurately and reliably over long distances.

Equipped with two DS18B20 stainless-steel digital probes, the D22-LB provides high-accuracy temperature readings from –55°C to +125°C with ±0.5°C typical accuracy. This makes it ideal for monitoring:

• Inlet / outlet lines

• Dual-zone refrigeration

• Soil at different depths

• Compost piles

• Hot/cold water lines

• HVAC supply/return

• Tanks, pipes, and insulated spaces

The sensor is housed in a rugged IP66 weatherproof enclosure and powered by an 8500mAh Li-SOCl₂ long-life battery, providing up to 5 years of operation depending on reporting intervals.

Using LoRaWAN Class A ultra-low-power technology, the D22-LB transmits readings over several kilometres and integrates seamlessly into AU915/AS923 LoRaWAN networks, including ProSight, TTN, ChirpStack, TagoIO, and private gateways.

It supports temperature alarms, BLE configuration, wireless OTA firmware updates, and on-device data logging — ensuring that no readings are lost during temporary network outages.

All ProSense LoRaWAN sensors — including this D22-LB model — are fully compatible with ProSight Monitoring Software, providing dashboards, reports, alerts, and long-term analysis.
Advanced users can also integrate the sensor into custom IoT or SCADA systems using standard LoRaWAN payloads.
