Milesight EM400-TLD | NB-IoT/Cat.M ToF Laser Distance & Smart Bin Sensor with GNSS

The Milesight EM400-TLD (NB-IoT/Cat.M) is a 3-in-1 cellular IoT sensor built for smart waste management — a gateway-free smart bin fill-level sensor that combines Time-of-Flight (ToF) laser measurement, GNSS asset tracking, and combustion detection in a single rugged unit.

Using ToF laser technology, it measures bin fill level across a 2–350 cm range with ±2 cm accuracy and a 27° field of view — virtually no blind spot on small and mini waste bins. An embedded NTC temperature sensor watches for combustion events, a 3-axis accelerometer detects lid status and tilt, and the NB-IoT/Cat.M1 radio connects directly to cellular networks with no LoRaWAN® gateway required. Two replaceable 9,000 mAh batteries deliver up to 10 years of maintenance-free operation. Ideal for municipalities, waste-management operators, and facilities teams running city-wide deployments.

Core Capabilities

Gateway-Free NB-IoT/Cat.M Connectivity Connects directly to NB-IoT and Cat.M1 cellular networks — no gateway required. Supports TCP, UDP, MQTT, and AWS IoT Core, with cumulative reporting of up to 24 packets per transmission for power-efficient operation. High-Accuracy ToF Fill-Level Detection 2–350 cm detection range with ±2 cm accuracy and 1 mm resolution. 27° field of view minimises blind spots in small-bin installations. Two pre-set modes — Standard and Bin — enable out-of-the-box deployment with no configuration required. Built-In GNSS Asset Tracking The integrated GNSS module provides longitude/latitude positioning with motion detection, so it uploads location data when a bin is on the move — ideal for route verification and asset security across large urban deployments. 10-Year Battery & IP67 Rugged Enclosure Two replaceable 9,000 mAh ER26500 Li-SOCl2 batteries deliver up to 10 years (TCP/UDP) of maintenance-free operation. IP67-rated ABS+PC enclosure with internal damp-proof PCBA coating ensures reliable performance outdoors.

Industrial Applications

• Smart Urban Waste Management: Deploy on public small and mini waste bins across cities, parks, and commercial districts to monitor fill levels in real time and optimise collection routes — reducing operational costs and unnecessary trips. • Mobile Bin & Asset Tracking: Use the built-in GNSS module to track bins, containers, and waste assets across routes, depots, and urban areas — including movement detection and periodic position reporting. • Fire & Combustion Detection: The embedded NTC temperature sensor monitors bin temperature and triggers alerts on abnormal heat, enabling rapid response to fire events in public spaces. • Gateway-Free Cellular Deployments: Ideal for city-wide rollouts where LoRaWAN® gateway infrastructure is impractical or cost-prohibitive — connects directly to existing cellular networks.

Technical Integration

Key points for connecting the EM400-TLD NB-IoT/Cat.M:

• Connectivity: Gateway-free NB-IoT and Cat.M1 cellular — no LoRaWAN® gateway required. • Application modes: Works with TCP, UDP, MQTT, and AWS IoT Core, with cumulative reporting of up to 24 packets per transmission. • SIM & power mode: Micro SIM (3FF) slot accepting 1.8 V cards; PSM (Power Saving Mode) required for optimal battery life. • Configuration: Wirelessly via NFC (Milesight ToolBox app), with remote configuration through downlink commands. • Setup help: For deployment planning, SIM provisioning, or platform-integration support, contact the shopioT technical team.

Frequently Asked Questions

Does the EM400-TLD NB-IoT/Cat.M need a LoRaWAN gateway?

No. This version connects directly to NB-IoT and Cat.M1 cellular networks, so no LoRaWAN® gateway is required. (A separate LoRaWAN model is available if you already run a gateway.)

What is the fill-level measurement range and accuracy?

It measures from 2 cm to 350 cm with ±2 cm accuracy and 1 mm resolution, across a 27° field of view.

How long does the battery last?

Up to 10 years on TCP/UDP, or around 5 years on MQTT/AWS, using two replaceable 9,000 mAh ER26500 Li-SOCl2 batteries. PSM must be enabled on the SIM for best results.

Do I need a SIM card, and what type?

Yes — a Micro SIM (3FF), 1.8 V, with PSM (Power Saving Mode) enabled. The SIM is not included.

Which IoT platforms does it support?

TCP, UDP, MQTT, and AWS IoT Core, making it compatible with most cloud and on-premise platforms.

Is it suitable for outdoor use?

Yes. The IP67-rated ABS+PC enclosure with damp-proof PCBA coating is built for outdoor, all-weather installation.
