Milesight environmental & building sensors — CO₂, temperature, leak, motion
Environmental and building automation sensors connect via LoRaWAN to Vemcount. All are battery-powered, up to 5–10 years life, and configured via NFC using the Milesight ToolBox app. Gateway required: Milesight UG65/UG67 or SG50 → ttn.vemcount.app UDP 1700.
WS202 — PIR & Light Sensor
Combined passive infrared motion detector and ambient light sensor. Triggers lighting control, HVAC adjustments, or security alerts based on occupancy and light levels.
Motion detection | PIR sensor — detects people and animals |
Light detection | Lux measurement — ambient light level |
Connectivity | LoRaWAN, Milesight D2D |
Use cases | Meeting room occupancy, lighting automation, energy management, security monitoring |
WS203 — Motion & Temperature/Humidity Sensor
Motion detection combined with environmental monitoring. Ideal for HVAC automation — activating climate control only when the space is occupied.
PIR coverage | 120° horizontal × 100° vertical, up to 6m range. Adjustable via different PIR covers. |
TH sensing | High-precision temperature and humidity in real time |
Battery | Up to 5 years — built-in 4000mAh ER18505 Li-SOCl₂ |
Data storage | Up to 1000 records with timestamps — retransmits when reconnected after network outage |
D2D | Direct control of HVAC without gateway |
Use cases | Office/meeting room HVAC automation, hotel room energy saving, retail comfort monitoring |
EM300-TH — Temperature & Humidity Sensor (Indoor/Outdoor)
Industrial-grade IP67 temperature and humidity sensor. Suitable for indoor and outdoor deployments — offices, greenhouses, warehouses, cold chain, food storage.
Accuracy | ±0.3°C temperature, ±3% RH humidity (Sensirion SHT-31 chip) |
Range | Temperature: -30°C to +70°C. Humidity: 0–100% RH |
Enclosure | IP67 — dust and waterproof, UV-resistant |
Battery | Up to 5 years standard (1× 4000mAh). Up to 10 years with second battery. |
Data storage | 3,000 historical records — retransmits on reconnect |
Configuration | NFC via Milesight ToolBox or USB-C on Windows |
Use cases | Cold chain monitoring, warehouse temperature, office comfort, HVAC zone sensing, greenhouse climate |
EM300-MLD — Membrane Leak Detection Sensor
Flexible membrane-type leak detection for large surface areas — placed under raised floors, along pipe runs, or in plant rooms. Detects moisture presence across the membrane surface.
Technology | Membrane-based conductivity detection |
Connectivity | LoRaWAN, D2D |
Use cases | Under-floor leak detection, plant rooms, data centres, IT rooms, pipe corridors |
EM300-SLD — Spot Leak Detection Sensor
Point-location water detection — placed at specific leak-prone points such as under sinks, around pipe joints, or at drain edges.
Technology | Spot conductivity probes |
Connectivity | LoRaWAN, D2D |
Use cases | Under sink, boiler, dishwasher, washing machine, HVAC unit water detection |
EM400-TLD — ToF Laser Distance Sensor
Measures the distance to an object using a laser Time-of-Flight beam. Used to monitor fill levels in waste bins, containers, tanks, and other open-top vessels.
Detection range | 2–350cm with very short blind zone |
Technology | Laser ToF distance measurement |
Connectivity | LoRaWAN, NB-IoT variants available |
Configuration | NFC / Power button. Supports threshold alarms, periodic reports. |
Mounting | Top-down inside container or bin. M4 mounting screws. |
Use cases | Waste bin fill level (small bins), liquid tank monitoring, retail fixture stock level, small container management |
WS101 — Smart Button
Wireless single-button trigger for any action — cleaning requests, emergency alerts, staff calls, or manual event logging. Battery-powered, no wiring needed.
Connectivity | LoRaWAN, D2D |
Actions | Single press, double press, long press — each configurable to different actions |
Use cases | Restroom cleaning request button, staff assistance call, manual footfall event trigger, emergency alert in accessible bathrooms |
AM Series — IAQ Sensors (CO₂, Temperature, Humidity)
Indoor Air Quality sensors for monitoring CO₂ levels, temperature, and humidity. Essential for ventilation control, meeting room air quality management, and occupancy-driven HVAC systems.
AM100/AM102 | CO₂, temperature, humidity, light, TVOC, barometric pressure (model-dependent) |
CO₂ technology | NDIR (non-dispersive infrared) — most accurate method for CO₂ detection |
Display | AM102 has built-in LCD screen showing real-time values |
Connectivity | LoRaWAN |
Use cases | Meeting room air quality, classroom CO₂ monitoring, office HVAC automation, smart building compliance |
