ALLNET ALL-PoE-CO2-LAMP CO2 Air Quality Traffic Light with RGBW LEDs, VOC Sensor, PoE & Wi-Fi

In a busy open-plan office, meeting room, or classroom, maintaining good air quality is essential for comfort and productivity. The ALLNET ALL-PoE-CO2-LAMP is a wall-mountable or desktop CO2 and VOC air quality monitor that provides clear visual feedback via a 3-color LED traffic light—green, yellow, and red—so everyone can instantly see when it's time to ventilate. With both Power over Ethernet (PoE) and Wi-Fi connectivity, it integrates seamlessly into existing networks, making it ideal for facility managers, school administrators, and office IT teams who need reliable, low-maintenance indoor air quality monitoring.

Key specifications

• CO2 sensor: NDIR (non-dispersive infrared) with automatic baseline calibration (ABC)
• CO2 measurement range: 400–5000 ppm, accuracy ±50 ppm + 5% of reading
• VOC sensor: metal oxide semiconductor (MOS) for total volatile organic compounds (TVOC) index
• Temperature measurement: 0–50 °C, accuracy ±0.5 °C
• Humidity measurement: 0–95 % RH (non-condensing), accuracy ±3 % RH
• Connectivity: Wi-Fi 2.4 GHz (802.11b/g/n) and Power over Ethernet (IEEE 802.3af)
• Alternative power input: USB-C (5V DC)
• Visual indicator: 3-color LED (green/yellow/red) for CO2 status
• Data interfaces: web interface, MQTT, HTTP API
• Supported protocols: IPv4, HTTP, MQTT, NTP
• Housing material: ABS plastic
• Mounting options: wall-mountable, desktop
• Power consumption: less than 3 W

Why choose it

This device combines accurate NDIR CO2 sensing with VOC detection and environmental monitoring in a single, easy-to-install unit. The RGBW LED traffic light provides at-a-glance air quality status without needing a smartphone or computer, while PoE support means a single Ethernet cable delivers both power and data—no separate power adapter required. Automatic baseline calibration keeps the CO2 sensor accurate over time, and open protocols like MQTT and HTTP allow integration with building management systems or custom dashboards.

Ideal use cases

• Offices and coworking spaces to maintain healthy CO2 levels and boost productivity
• Schools and classrooms to signal ventilation needs during lessons
• Meeting rooms and conference areas where occupancy varies
• Healthcare waiting rooms and clinics for continuous air quality monitoring
• Smart building installations requiring PoE-powered sensors with MQTT integration

Good to know

The ALL-PoE-CO2-LAMP is designed for simple deployment: mount it on a wall or place it on a desk, connect it to a PoE switch or use the included USB-C power option, and it will start monitoring immediately. The CO2 sensor uses automatic baseline calibration to maintain accuracy, and the device supports firmware upgrades for future enhancements. With its robust ABS housing and low power consumption, it is built for continuous operation in indoor environments.
