The Dragino NDDS75 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.
LDDS75 is powered by 8500mAh Li-SOCI2 battery. It is designed for long term use up to 5 years.
This sensor node uses Quectel BC95-G. This module supports B1/B3/B8/B5/B20/B28.
NB-IoT and LTE-M are very new services. Ask your mobile operator about availability of SIM cards, coverage, frequencies used and login procedures before you buy this product. See for example Deutsche Telekom IoT.
NDDS75 has an external antenna and an IP66 enclosure with a waterproof external sensor. With a USB to TTL adapter, you can use AT commands to configure the NDDS75.
