Milesight offers a full suite of IoT sensors that directly support ESG reporting — energy monitoring, air quality, water management, and smart control — beyond just occupancy counting. All connect via LoRaWAN to Vemcount IoT dashboards. Gateway required: Milesight UG65/UG67/SG50 → ttn.vemcount.app UDP 1700.
Buildings generate 34% of global CO₂ emissions. Milesight sensors directly address all three pillars:
Environmental — energy submetering identifies wasteful loads; CO₂ monitoring drives demand-controlled ventilation; water monitoring prevents waste
Social — IAQ monitoring ensures healthy indoor environments; CO₂ <1000ppm directly improves cognitive performance
Governance — automated, auditable data for BREEAM, LEED, WELL, EU EPBD compliance, and sustainability disclosures
The core ESG energy sensor. Non-invasive clamp-on design — installs on live wires in existing panels without cutting power or rewiring. Provides circuit-level consumption data for Scope 2 carbon calculations.

Measurement | True RMS current, accumulated ampere-hours (kWh equivalent) |
Accuracy | ±1% for currents >5A, ±3% at or below 5A |
Sampling rate | 3.3 kHz — captures harmonics and transients |
Self-powered | Powered from the monitored circuit — no battery, no wiring |
Temperature probe | External NTC included (-20°C to +100°C) — detects overheating equipment |
No shutdown needed | Installs on live wires — ideal for occupied buildings, schools, hospitals, concert halls |
ESG uses | Scope 2 electricity reporting, energy audits, identifying waste, net-zero tracking, per-tenant submetering |
CT303, CT305, CT310 for three-phase industrial/commercial systems. Same non-invasive principle — essential for manufacturing, data centres, and large commercial buildings.
Drops straight into existing wall boxes as a direct retrofit replacement for standard switches. Adds LoRaWAN remote control AND per-circuit energy monitoring simultaneously.
Models | WS501 (1-gang), WS502 (2-gang) |
Measurements | Voltage (VAC), current (mA), active power (W), power factor, energy (kWh) per gang |
Accuracy | ±3% typical, ±5% max |
Control | Local button or remote via LoRaWAN — schedule automated after-hours shutdown |

ESG uses | Lighting energy monitoring per room/zone, automated shutdown schedules, individual circuit ESG data |
In-wall smart socket (EU Type F/FR Type E). Monitors plugged-in device consumption in real time. Remote ON/OFF — eliminates standby waste.

Control | Remote ON/OFF, scheduled switch, multicast (up to 4 devices), D2D automation |
ESG uses | Standby power elimination, plug-load monitoring, per-workstation energy tracking |
Connects to any existing meter with pulse output — water meters, gas meters, electricity meters. Converts pulses to wireless LoRaWAN data. The fastest path to utility submetering without replacing meters.
Compatible signals | Dry contact, reed switch, open collector pulse outputs |
Noise filtering | Auto-filters signals <250μs — prevents false counts from nearby electrical equipment |
ESG uses | Water consumption (litre-level), gas consumption, electricity submetering per floor/tenant, automated utility ESG reporting |
Indoor air quality is a core ESG-Social metric. CO₂ >1000ppm causes measurable cognitive decline; optimal range is 400–800ppm.
AM102 / AM102L | CO₂ + Temperature/Humidity. Entry level, up to 9 years battery. |
AM103 / AM103L | CO₂ + Temperature + Humidity. Tri-colour LED + emoticon display. 3–4 year battery. NDIR double-band CO₂ (factory calibrated). NFC config. |
AM307 / AM308 | 9-in-1: CO₂, Temperature, Humidity, Light, TVOC, PM2.5, PM10, Barometric pressure + HCHO or O₃. E-ink display option. |
AM319 | Full 9-in-1 IAQ with E-ink screen and emoticon comfort indicator. Comprehensive parameter set for WELL/BREEAM evidence. |
Coverage guide: 1 sensor per 100–150m² for offices and classrooms. High-traffic areas require additional coverage.
ESG uses: WELL Building certification, BREEAM credits, demand-controlled ventilation (auto-trigger HVAC on CO₂ levels), occupant health KPIs, IAQ compliance reporting.
Best ESG ROI combination: AM103 CO₂ sensors + Milesight WT thermostats or HVAC controllers via D2D. HVAC activates automatically when CO₂ exceeds threshold — maintains air quality while eliminating unnecessary ventilation energy use. This is demand-controlled ventilation without BMS integration.
Industrial outdoor CO₂ + Temperature + Humidity + Barometric pressure. NDIR double-band sensor. Up to 15km rural range. For perimeter carbon monitoring, greenhouse gas stations, outdoor campus air quality, and carbon capture verification.
Measures liquid levels in wells, tanks, and open water — essential for water consumption monitoring and conservation. Designed for harsh outdoor environments.
ESG uses: Water tank level monitoring, rainwater harvesting, irrigation consumption tracking, flood early warning.
EM300-MLD | Membrane type — large surface areas, under raised floors, along pipe corridors |
EM300-SLD | Spot type — targeted points (under sinks, around joints, at drains) |
ESG uses: Water waste prevention, early maintenance alerts, water conservation reporting.
0.5mm detection threshold, IP67, 5-year battery, gold-plated probes. Compact spot detector for bathrooms, plant rooms, kitchens, and server rooms. See restroom sensors article for full specs.
Configurable for CO, H₂S, NO₂, O₃, SO₂, and other gases. Worker safety and indoor air quality compliance in industrial or semi-industrial environments. D2D for direct ventilation activation.
Industrial-grade outdoor sensors: soil moisture (EM500-SMT), pipe pressure (EM500-PP), water level (EM500-SWL), CO₂ (EM500-CO2), PT100 temperature probes (EM500-PT100). For campus environmental monitoring and outdoor infrastructure tracking.
