Solar-Powered LoRaWAN Triple Temperature Sensor – 3× DS18B20 Waterproof Probes

The D23-LS Solar-Powered LoRaWAN Triple Temperature Sensor is a high-accuracy, low-power device designed for applications requiring three independent temperature measurements at once. Powered by an integrated solar panel and long-life Li-ion battery, it is ideal for remote, off-grid installations where maintenance must be minimal.

Equipped with three stainless-steel DS18B20 waterproof temperature probes, the sensor measures –55°C to +125°C with ±0.5°C typical accuracy. This triple-probe design allows simultaneous monitoring of:

• Soil temperature at three depths

• Compost core, mid-layer, and outer shell

• Triple-zone refrigeration or freezers

• Inlet, mid-line, and outlet process temperatures

• Multiple water points, tanks, or pipes

• Environmental or agricultural multi-point sensing

The D23-LS uses LoRaWAN Class A long-range wireless technology, enabling multi-kilometre communication with extremely low power consumption. It seamlessly integrates with AU915/AS923 gateways, including ProSight, TTN, ChirpStack, TagoIO, and private LoRaWAN networks.

The rugged IP66 waterproof and dustproof enclosure ensures reliable operation in harsh outdoor environments including farms, mines, irrigation networks, greenhouses, compost facilities, and environmental monitoring stations.

The device also includes BLE configuration, OTA firmware updates, temperature alarm thresholds, and local datalogging—ensuring temperature readings are captured and uploaded even if network coverage temporarily drops out.

This device works seamlessly with ProSight Monitoring Software, providing dashboards, alarms, historical trends, charts, and easy multi-site management.
Advanced users can integrate it into their own IoT or SCADA platforms using standard LoRaWAN payloads.

ProSense stocks this model in Australia, ensuring fast delivery and full local technical support.
