Powered by an 8500 mAh Li-SOCI2 Battery
Offers a LoRaWAN Ultrasonic liquid level sensor
Waterproof Enclosure: IP66
Ultra-low power consumption
Uses non-contact method to measure the height of liquid
The Dragino NDDS20 NB-IoT Liquid Level Sensor is a LoRaWAN Ultrasonic liquid level sensor for the Internet of Things solution. It uses a non-contact method to measure the height of liquid in a container without opening the container and send the value via the LoRaWAN network to IoT Server.
NDDS20 sensor is installed directly below the container to detect the height of the liquid level. The user doesn’t need to open a hole in the container to be tested. The non-contact measurement makes the measurement safe, easier, and possible for some strict situations. NDDS20 is powered by an 8500mAh Li-SOCI2 battery.
NDDS20 uses ultrasonic sensing technology for distance measurement. NDDS20 is of high accuracy to measure various liquids such as toxic substances, strong acids, strong alkalis, and various pure liquids in high-temperature and high-pressure airtight containers. NDDS20 supports different uplink methods including TCP, MQTT, UDP, and CoAP for different application requirements.
