Overview

Breathe Smarter. Live Healthier.

KEYPLUS Smart Carbon Dioxide & Air Quality Detector (TCS0301R)

The KEYPLUS TCS0301R is an advanced Smart Carbon Dioxide and Air Quality Detector engineered for modern residential and commercial spaces. Powered by a stable NDIR sensor and wide-voltage AC supply with a backup lithium battery, it provides precise, real-time measurements of indoor CO\u2082 levels alongside 24-hour average and peak data on a crisp LCD screen. With optional multi-parameter expansion (Temperature, Humidity, HCHO, TVOC, PM2.5) and flexible Zigbee/WiFi connectivity, it is the ultimate solution for automated ventilation and healthy indoor environments.

Pain Points & Challenge

Can You See the Invisible Threat in Your Room?

In tightly sealed modern offices, classrooms, and bedrooms, stale air builds up silently:

The Hidden Fatigue Trap: High CO\u2082 levels cause headaches, fatigue, and lower productivity, yet people often mistake it for lack of sleep.
Blind Ventilation Control: Traditional HVAC systems run blindly without knowing the actual air quality index.
Unreliable Single-Parameter Devices: Basic detectors only measure temperature, leaving harmful pollutants, VOCs, and carbon dioxide undetected.

Key Capabilities & Benefits

Professional-Grade NDIR CO\u2082 Sensing

Feature: Built-in stable NDIR (Non-Dispersive Infrared) sensor technology.
Advantage: Accurately isolates and measures carbon dioxide molecules without interference from other gases, ensuring laboratory-grade precision over long lifespans.
Benefit: Trust the data you see. Protect your family, students, or employees from the cognitive decline caused by high indoor carbon dioxide concentrations.
