    Home » LoRaWAN ToF Laser Distance / Level Sensor EM400-TLD

    EM400-TLD ToF
    Laser Distance Sensor

    Highly Specialized, Reliable and Durable

    • 3-in-1 Sensor Specialized for Smart Waste Management
      (Fill Level, Device Position, and Combustion)
    • High Accuracy and Almost No Blind Spot
    • Two Pre-set Modes for Seamless User Experience
    • Long-Lasting Battery Life of up to 10 Years
    • Rugged and Reliable IP67 Rated Enclosure
    • Positioning Function Enabled by GNSS Modules (NB-IoT version)

    EM400-TLD is a highly specialized product among the EM400 Series, which is designed for small & mini trash bins, boasts a range of powerful features, including the ability to detect overflowing garbage, the status of the garbage bin lid, and trash combustion. With pre-set modes that save users from configuration, EM400-TLD is the ideal solution for smart waste management, providing a long-lasting performance that customers can rely on. Additionally, its availability in both LoRaWAN and NB-loT versions allows for a varietv of application scenarios.

    Get to Know Our Powerful and Versatile EM400 Series

    (LoRaWAN® Version)

    LoRaWAN® and NB-IoT Versions

    Flexible and Broad Applications

    LoRaWAN® Version

    • Wide Area Coverage: Data transmission range up to 2 km in urban areas and 15 km in rural areas
    • Power Saving: Low battery consumption enabled by LoRaWAN® technology
    • More Deployment Freedom: Deployment options based on both private and public network facilities

    NB-IoT Version

    • Stable Transmission: Reliable data transmission via cellular base stations
    • Positioning Capability: Equipped with GNSS module to help track your assets
    • Low Deployment Cost: Low deployment cost due to the presence of existing cellular base stations
    • Cumulative Reporting: Accumulate up to 24 data packets in each report, saving transmission cost and power consumption

    High Accuracy Guaranteed
    By ToF

    EM400-TLD employs time-of-flight (ToF) to detect and measure the distance to objects, ensuring almost no blind spots and a stable performance. Leveraging ToF technology, EM400-TLD can effectively monitor the fill level of small & mini trash bin with high accuracy and alert users to empty trash in time.

    Specialized for Small Trash
    Bin Monitoring

    Device Position/Device Tilt Status Monitoring

    The EM400-TLD is equipped with a built-in 3-axis accelerometer to detect the device position, which can be used to monitor the opening and closing of the trash bin lid.

    Combustion Monitoring

    With built-in NTC thermistor, EM400-TLD can monitor the temperature inside the garbage bin and send alert in time if combustion occurs.

    Pre-set Modes for Better
    User Experience

    EM400-TLD comes equipped with two pre-set modes, namely the Standard mode and Bin mode, each designed to cater to the common requirements of distance measurement and waste bin monitoring applications. These modes are configured with different data collection and report intervals to ensure optimal performance. With these ready-to-use modes available, users can integrate EM400-TLD into monitoring solutions quickly.

    Rugged and Reliable IP67
    Rated Enclosure

    IP67 rated enclosure ensures EM400-TLD is protected against dust, water, and other environmental hazards, enabling it to withstand harsh environment.

    EM400-TLD also features a conformal coating on its PCBA, which provides an extra layer of protection against moisture, dust, and other contaminants that can damage electronic components.

    These two features extend the lifespan of the EM400-TLD and ensure that it continues to function reliably in harsh conditions.

    Ultra-long Battery Life of
    up to 10 Years

    EM400-TLD is equipped with high-capacity and easily-replaceable batteries. This facilitates the installation and maintenance process and reduces wiring costs. The conditions of battery life are specified below:

    • LoRaWAN® Version:

      Standard mode: Over 10 years (10-min interval, 25 °C)
      Bin mode: Over 10 years (20-min interval, 25 °C)

    • NB/Cat.M Version:

      TCP/UDP—10 years, MQTT/AWS—5 years (4 times report per day, each report includes 12 packages with 30-min collection interval, 25 °C)
