It accurately measures the distance between the sensor and flat objects, with built-in temperature compensation for reliable data. Powered by an 8500mAh Li-SOCI2 battery, it supports years of operation, making it ideal for liquid level monitoring, smart parking, trash bin management, sewer water level detection, and more. With support for NB-IoT uplink protocols such as MQTT, MQTTs, UDP, and TCP, the DDS75-NB is compatible with various IoT platforms. It also features BLE configuration, OTA updates, and an optional built-in SIM card for easy setup and deployment. This makes it a versatile and energy-efficient solution for smart cities, industrial, and automation applications. NBIoT Cellular Communication Fully compatible with Australian telcos narrowband network, DDS75 can also upload data via the existing cellular network with ultra-low power consumption. Ultra-Low Power & Long Battery Life Designed for long-term deployment, the sensor is powered by an 8500mAh battery, allowing up to 5 years of operation without frequent maintenance. This energy-efficient design reduces the need for battery replacements, making it cost-effective and reliable. BLE Configuration & OTA Updates The device supports Bluetooth Low Energy (BLE) configuration and over-the-air (OTA) firmware updates, enabling users to set up and upgrade the device remotely. This eliminates the need for manual intervention, simplifying deployment and maintenance. Dragino DDS75-NB Ultrasonic Distance Sensor The Dragino DDS75-NB is an easy-to-use ultrasonic sensor that measures the distance between the sensor and flat objects. It works well in many places like checking water levels, parking spots, and trash bins. The sensor has built-in temperature correction for accurate readings and a waterproof case to protect it outdoors. It uses a long-lasting 8500mAh battery and connects to the internet using NB-IoT, sending data to your platform. You can set it up and update it easily with Bluetooth and wireless updates. It’s a simple and reliable solution for smart monitoring. Details
