NDDS20 NB-IoT Waterproof LPWAN Liquid Level Sensor Libelium Waspmote Sensors 2*4K60 | 4*4K30 | 10*1080p60NDDS20 NB IoT Waterproof LPWAN Liquid Level Sensor The Dragino NDDS20 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 LoRaWAN network to IoT Server. NDDS20 sensor is installed directly below the container to detect the height of the liquid level. The user doesnt need to open a hole in the
