The Dragino Outdoor LoRaWAN Open/Close Dry Contact Sensor is an advanced device designed for Internet of Things applications, capable of detecting dry contact status and recording open times and counts. It communicates with IoT servers using the LoRaWAN wireless protocol, offering ultra-long range communication with high interference immunity and low power consumption. This sensor is engineered for outdoor environments, featuring a weatherproof enclosure and an industrial-grade battery, ensuring reliable performance across a wide temperature range.
The sensor provides periodic data transmission and can be configured to send updates for each contact action or at regular intervals. It includes an open alarm feature for immediate notifications and a Datalog function to store data when the network is unavailable, uploading it once connectivity is restored. The device supports Bluetooth configuration and wireless over-the-air firmware updates, enhancing ease of use and adaptability.
Powered by either an 8500mAh Li-SOCI2 battery or a combination of solar power and a Li-ion battery, the sensor is designed for long-term operation, with a lifespan of up to five years. Each unit comes pre-loaded with unique keys for seamless LoRaWAN registration and automatic connection upon activation.
