EM400-UDL Ultrasonic Distance Sensor NB-IoT

Milesight EM400 Series, our versatile and powerful distance measuring sensor series, is now offered in both NB-IoT and LoRaWAN® versions. By enriching the EM400 Series with NB-IoT versions, we are able to leverage the unique features of NB-IoT technology to broaden the application possibilities of these sensors and provide extra benefits to our customers. By comparison, the EM400 NB-IoT version prevails in situations where gateway deployment is difficult and device deployment is sparse. This version is also advantageous when users require the location data of the objects. Non-Contact Distance Measurement Leveraging ultrasonic distance detection, EM400-UDL ensures a stable and reliable performance while detecting different solid or liquid mediums. Featuring non-contact distance measurement, the probe of EM400-UDL will remain unaffected or contaminated by the medium detected, and deliver highly accurate measurement. Why NB-IoT Version? Reliable Data Transmission Data transmission under NB-IoT protocol is based on existing cellular stations, which is highly reliable. In the industrial setting, the accuracy and completeness of distance data are important as data loss or error could cause mistakes in subsequent operations and decision-making. Therefore, by utilizing the steadfast and secure connection provided by cellular stations, asset managers can confidently rely on the data reported to take responsive actions and make informed decisions accordingly. Positioning Capability The new NB-IoT distance measuring sensors are now equipped with GNSS modules, which allows the users to monitor the location of the object. GNSS modules are electronic components that can receive signals from multiple satellite constellations, such as GPS, GLONASS, Galileo, and BeiDou. Users will get notification about object locations at the beginning and end of its movement. And periodic location notification can also be triggered by setting a motion report interval for moving status. Low Deployment Cost NB-IoT devices leverage existing cellular infrastructure to operate within the allocated frequency bands, thus eliminating the needs to purchase and install gateways and other relevant devices. This helps customers save on deployment costs. Cumulative Reporting EM400 NB-IoT version allows users to customize the data packet amount up to 24 in each report. We developed this function because users in different scenarios may have different needs for the number of data packets contained in each report. Cumulative reporting creates the flexibility to set data packet size according to the specific needs. Additionally, reporting data in bulk allows users to save on transmission costs and reduce power consumption. This makes the entire process more efficient and budget-friendly. High Compatibility Our NB-IoT distance measuring sensors are also compatible with multiple protocols such as MQTT, TCP, and UDP as well as different platforms such as Amazon Web Services and Milesight IoT Cloud. This high compatibility gives users the freedom to choose the platform that best suits their specific requirements and infrastructure, providing extra flexibility and interoperability. Leveraging cellular network connectivity, data captured by EM400 NB-IoT version can be transmitted to application servers such as Amazon Web Services and Milesight IoT Cloud and other third party platforms via MQTT, TCP, and UDP protocols. This provides a convenient way for users to view, retrieve, and store the data on the platform that is already in use. Therefore, users can take proper actions timely and derive relevant insights via thorough analysis of the data.
