Dragino D20 LoRaWAN: long-range waterproof outdoor temperature sensor<\/h2>\n

The Dragino D20 LoRaWAN<\/strong> is a waterproof outdoor temperature sensor rated IP66<\/strong>, designed for long-range IoT<\/strong> deployments. Fitted with a Dallas DS18B20<\/strong> probe on a 2-meter cable, it measures temperatures from -55 \u00b0C \u00e0 +125 \u00b0C<\/strong> with \u00b10.5 \u00b0C accuracy, then sends its readings via LoRaWAN<\/strong> to your gateway and IoT platform (TTN, ChirpStack, Actility, etc.).<\/p>\n

Built for years of autonomy, the D20 LoRaWAN comes in three versions depending on the power source: 8,500 mAh Li\/SOCl\u2082 battery (D20-LB)<\/strong>, long-life 19,000 mAh Li\/SOCl\u2082 battery (D20-LB2)<\/strong> or solar panel (D20-LS)<\/strong>. A turnkey solution for smart agriculture, supply chain, smart metering, connected buildings and smart cities.<\/p>\n

              Frequently asked questions (FAQ)<\/h2>\n

              What is the battery life of the D20 LoRaWAN?<\/h3>\n

              Depending on the uplink frequency and the version, battery life can reach several years<\/strong>, 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.<\/p>\n

              Which version should I choose: LB, LB2 or LS?<\/h3>\n

              D20-LB<\/strong> : best battery life\/price ratio, perfect for most installations. D20-LB2<\/strong> : maximum battery life thanks to the 19,000 mAh battery, ideal for hard-to-reach sites. D20-LS<\/strong> : the battery-maintenance-free solution, recommended outdoors in sunny locations for continuous operation.<\/p>\n

              Do I need a LoRaWAN gateway to use the D20?<\/h3>\n

              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)<\/strong>, ChirpStack<\/strong>, Actility<\/strong>, Helium<\/strong> or a private network.<\/p>\n

              Can the D20 withstand outdoor conditions?<\/h3>\n

              Yes, the enclosure is IP66<\/strong> and the operating range is -40 \u00b0C to +85 \u00b0C. It is designed to stay outdoors all year round.<\/p>\n

              Can a temperature alarm be configured?<\/h3>\n

              Yes. The D20 includes aTemperature alarm<\/strong> function that triggers an immediate transmission when the value exceeds a configurable high or low threshold, in addition to the periodic transmissions.<\/p>","protected":false},"excerpt":{"rendered":"
