LDDS45 LoRaWAN Distance Detection Sensor
The Dragino LDDS45 is a LoRaWAN 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 3cm to 450cm with high accuracy. Temperature compensation is performed internally to improve the accuracy of data. The measured values are uploaded wirelessly to the LoRaWAN IoT Server.
LDDS45 is powered by 8500mAh Li-SOCI2 battery. It is designed for long term use up to 10 years.
Each LDDS45 is pre-loaded with a set of unique keys for LoRaWAN registrations. If you register these OTAA keys to the local LoRaWAN server (e.g. TTN), then it will auto connect after power on.
