Solar-Powered LoRaWAN Dual Temperature Sensor – Dual DS18B20 Waterproof Probes

The D22-LS Solar-Powered LoRaWAN Dual Temperature Sensor is designed for long-term, off-grid temperature monitoring across agricultural, industrial, refrigeration, and environmental applications. With two independent DS18B20 stainless-steel probes, the sensor can measure and compare temperatures at two different points, making it ideal for:

• Dual-zone refrigeration

• Soil temperature at two depths

• Compost & waste monitoring

• Hot/cold pipe monitoring

• HVAC supply/return

• Tank and pipeline monitoring

• Greenhouse & horticulture

Each probe measures –55°C to +125°C with ±0.5°C typical accuracy, ensuring reliable performance even in demanding environments.

The integrated solar panel recharges the internal Li-ion battery, providing significantly longer operational life compared to battery-only models. Combined with an IP66 weatherproof enclosure, the sensor is built for harsh outdoor conditions including rain, dust, moisture, and UV exposure.

Using LoRaWAN Class A low-power wireless technology, the D22-LS transmits temperature data over long distances and integrates effortlessly with AU915/AS923 LoRaWAN networks, including ProSight, TTN, TagoIO, ChirpStack, and private gateways.

Additional features include temperature alarms, BLE mobile configuration, OTA firmware updates, and data logging to store readings during network outages.

All ProSense LoRaWAN sensors — including the D22-LS — are fully compatible with ProSight Monitoring Software, providing dashboards, alerts, reports, trend analysis, and temperature history.
Advanced users can integrate it into their own IoT or SCADA system using standard LoRaWAN payloads, MQTT bridges, or API endpoints.

ProSense stocks this sensor in Australia, with full local technical support.
