Dragino D20 LoRaWAN: long-range waterproof outdoor temperature sensor
The Dragino D20 LoRaWAN is a waterproof outdoor temperature sensor rated IP66, designed for long-range IoT deployments. Fitted with a Dallas DS18B20 probe on a 2-meter cable, it measures temperatures from -55 °C à +125 °C with ±0.5 °C accuracy, then sends its readings via LoRaWAN to your gateway and IoT platform (TTN, ChirpStack, Actility, etc.).
Built for years of autonomy, the D20 LoRaWAN comes in three versions depending on the power source: 8,500 mAh Li/SOCl₂ battery (D20-LB), long-life 19,000 mAh Li/SOCl₂ battery (D20-LB2) or solar panel (D20-LS). A turnkey solution for smart agriculture, supply chain, smart metering, connected buildings and smart cities.

Why choose LoRaWAN for your temperature sensors?
LoRaWAN technology LoRaWAN offers a range of up to several kilometers in open areas, with no carrier subscription. It is the ideal solution for farms, campuses, private industrial sites, municipalities and large infrastructure, where you can deploy your own LoRaWAN gateway. With its very low data rate and minimal power consumption, the D20 can send its readings for years on a single battery.
Applications
- Smart agriculture : greenhouses, orchards, livestock, crop monitoring
- Connected buildings & home automation : HVAC, technical monitoring, BMS
- Supply chain & cold chain : warehouses, refrigerators, storage rooms
- Smart metering : remote meter reading, heating networks, hot water
- Smart cities : street furniture, urban monitoring
- Smart factories (Industry 4.0) : predictive maintenance, process monitoring
- Temperature monitoring in data centers and technical rooms
Frequently asked questions (FAQ)
What is the battery life of the D20 LoRaWAN?
Depending on the uplink frequency and the version, battery life can reach several years, especially with the 19,000 mAh battery (D20-LB2). The solar-powered D20-LS offers virtually unlimited operating time as long as there is enough sunlight.
Which version should I choose: LB, LB2 or LS?
D20-LB : best battery life/price ratio, perfect for most installations. D20-LB2 : maximum battery life thanks to the 19,000 mAh battery, ideal for hard-to-reach sites. D20-LS : the battery-maintenance-free solution, recommended outdoors in sunny locations for continuous operation.
Do I need a LoRaWAN gateway to use the D20?
Yes. The D20 transmits its data via a compatible LoRaWAN gateway (Dragino, Multitech, Kerlink, etc.) connected to a LoRaWAN network server such as The Things Network (TTN), ChirpStack, Actility, Helium or a private network.
Can the D20 withstand outdoor conditions?
Yes, the enclosure is IP66 and the operating range is -40 °C to +85 °C. It is designed to stay outdoors all year round.
Can a temperature alarm be configured?
Yes. The D20 includes aTemperature alarm function that triggers an immediate transmission when the value exceeds a configurable high or low threshold, in addition to the periodic transmissions.
