EL-WEM+ CO2 & Indoor Air Quality Monitor
Wi-Fi connected indoor air quality monitor measuring CO2, particulates, VOCs, temperature, humidity and pressure.
Key Features
- Measures CO2, temperature, humidity, VOCs, pressure, PM1/PM2.5/PM10 in one device
- Five-level real-time air quality rating (Excellent to Inadequate)
- Coloured status ring plus audible sounder alert on poor air quality
- Email and SMS notifications on air quality degradation
- Do Not Disturb / night mode schedules quiet periods
- Continuous upload to EasyLog Cloud with app-based access
- Internal back-up power
Overview
The EL-WEM+ is an indoor air quality (IAQ) monitor that measures and records CO2, temperature, humidity, VOCs, pressure, and particulates (PM1, PM2.5, PM10) in a single device. It continually rates air quality on a five-level scale from Excellent to Inadequate. If air quality drops to the two lowest levels, the device's status ring turns red, an onboard sounder activates, and email/SMS notifications can be sent to selected contacts immediately.
Working Principle
An integrated multi-sensor array continuously samples CO2, particulate matter, VOCs, temperature, humidity and barometric pressure, then classifies overall indoor air quality into one of five bands in real time. Readings are automatically uploaded to EasyLog Cloud for viewing, analysis and download from any internet-enabled device via the EasyLog App, while an internal back-up power supply and a configurable Do Not Disturb mode allow scheduled quiet periods without losing monitoring continuity.
Applications
Benefits
- Single device replaces multiple standalone sensors for full IAQ picture
- Immediate local + remote alerting shortens response time to poor air quality
- Cloud history supports compliance and facilities reporting
- Do Not Disturb mode keeps it practical for bedrooms and quiet offices
