Dragino LDDS20 LoRaWAN Ultrasonic Liquid Level Sensor (EU868) Outlet Where Can You Find

Product Description

The Dragino LDDS20 is a LoRaWAN Ultrasonic Liquid Level Sensor designed for Internet of Things (IoT) solutions. This sensor uses a non-contact method to measure the height of liquid in a container, making it a safe and convenient solution for various applications. It is particularly suitable for measuring various liquids, including toxic substances, strong acids, strong alkalis, and pure liquids in high-temperature and high-pressure airtight containers.

The LDDS20 employs ultrasonic sensing technology for distance measurement and is characterized by its high accuracy. It offers an ultra-long range spread spectrum communication and high interference immunity while minimizing current consumption. The sensor is powered by an 8500mA Li-SOCI2 battery and is designed for long-term use, up to 10 years.
