Distance sensor Dragino LDDS75 LoRaWAN

LDDS75 is it LoRaWAN distance sensor for an Internet of Things solution. It is used to measure the distance between the sensor and a flat object. The distance sensor is a module that uses ultrasonic distance measurement technology, and temperature compensation performed internally to improve data reliability.

The LDDS75 can be applied to scenarios such as horizontal distance measurement, liquid level measurement, parking control system, object proximity and presence detection, intelligent garbage can control system, robot obstacle avoidance, automatic control, sanitation, groundwater level monitoring, etc.

He defines the distance between the measurement object and the sensor and uploads the values ​​over a wireless connection to the LoRaWAN IoT server. The LoRa wireless technology used in the LDDS75 allows the device to send data and reach extremely long distances at low data rates. It provides ultra-long range spread-spectrum communication and high immunity to interference while minimizing current consumption. LDDS75 is powered by 4000mA or 8500mA Li-SOCI2 batteries ; Designed for long-term use up to 10 years*. Each LDDS75 pre-downloads a set of unique LoRaWAN registration keys, registers these keys with the local LoRaWAN server, and it automatically connects if there is network coverage upon power-up. * Actual service life depends on network coverage, uplink interval and other factors.
