DDS75-NS Solar Powered NB-IoT Distance Detection Sensor

The Dragino DDS75-NS is a NB-IoT Distance Detection Sensor, designed for outdoor use (IP66). It measures the distance between the sensor and a flat object. The distance detection sensor is a module that uses ultrasonic sensing technology for distance measurement of 0.3m to 7.5m. Temperature compensation is performed internally to improve the accuracy of data. The measured values are uploaded wirelessly to an IoT Server via NB-IoT network.

You can use various IoT Servers and different uplink methods including MQTT, MQTTs, UDP and TCP. 

The sensor node uses Quectel BC660K-GL Multi-band LTE Cat NB2 module which can be used in most European countries. It has a card slot for an NB-IoT SIM card. 

This device supports BLE for easy configuration and wireless OTA to update the firmware.

DDS75-NS is powered by a rechargeable battery with solar cell and allows continuous use.
