The Dragino S31B-LS LoRaWAN Outdoor Temp. & Humidity Sensor (3000mAh Li-Ion & Solar Panel / US915) is engineered for precise environmental monitoring, specifically designed for Internet of Things applications. It accurately measures temperature and relative humidity, transmitting this data to an IoT server using the LoRaWAN wireless protocol. The sensor incorporates the SHT31, known for its full calibration, linearization, and temperature compensation, ensuring high reliability and stability over extended periods. Encased in a waterproof, anti-condensation housing, it is suitable for long-term outdoor use.
Leveraging LoRa wireless technology, the device facilitates data transmission over extensive distances at low data rates, providing robust communication with high interference resistance while conserving energy. The S31B-LS includes features such as temperature and humidity alarms, enabling users to receive immediate notifications when set thresholds are exceeded. Additionally, it offers a data logging capability, storing information during network outages and uploading it once connectivity is restored.
The sensor supports Bluetooth configuration and wireless over-the-air updates, enhancing user convenience. It is powered by a solar panel and a 3000mAh Li-ion battery, designed to last up to five years. Each unit is pre-configured with unique keys for seamless LoRaWAN registration, allowing automatic connection to local servers upon activation. The device is ideal for applications in wireless alarm systems, home automation, industrial monitoring, and long-range irrigation systems, thanks to its IP66 waterproof rating and robust design.
