The Dragino S31-LS LoRaWAN Outdoor Temp. & Humidity Sensor (3000mAh Li-Ion & Solar Panel / US915) is an advanced device engineered for precise environmental monitoring in Internet of Things applications. It accurately measures ambient temperature and relative humidity, transmitting this data to an IoT server via the LoRaWAN wireless protocol. The sensor, utilizing the SHT31, is fully calibrated, linearized, and temperature compensated, ensuring high reliability and long-term stability. Encased in a waterproof, anti-condensation housing, it is designed for enduring outdoor use.
Employing LoRa wireless technology, the S31-LS facilitates data transmission over extensive distances with low data rates, offering ultra-long range communication and robust interference resistance while conserving energy. It features a Temperature & Humidity alarm for instant notifications and a Datalog function to store data during network outages, uploading it once connectivity is restored.
The device supports Bluetooth configuration and wireless over-the-air updates, enhancing user convenience. Powered by a solar panel and a 3000mAh Li-ion battery, it is built for longevity, with an operational lifespan of up to five years. Pre-loaded with unique keys for LoRaWAN registration, the S31-LS automatically connects to a local server upon activation.
Applications for this sensor include wireless alarm and security systems, home and building automation, automated meter reading, industrial monitoring and control, and long-range irrigation systems.
