VentPlus CO2 Monitor and Controller with Remote monitoring - Main Unit

India's First Automatic CO2 Monitor & Ventilation Controller

Stale, stuffy indoor air causes fatigue, headaches, poor concentration and crop losses — and because CO2 is colourless and odourless, you never see it happening. The Systellar VentPlus CO2 Monitor & Controller is India's first smart carbon dioxide monitor that doesn't just measure the air — it acts on it. Using an industrial-grade NDIR (Non-Dispersive Infrared) sensor, VentPlus continuously tracks CO2, temperature and humidity, and automatically switches your fan or ventilation on and off to keep air quality exactly where it should be — 24×7, hands-free. Proudly Made in India and built for Indian mains and high-humidity conditions, it's the ideal indoor air quality (IAQ) solution for offices, homes, schools, mushroom farms, greenhouses and more.

Why You'll Love This:

• Monitors AND Controls: Unlike ordinary CO2 meters that only display a number, VentPlus is a true automatic CO2 controller — it triggers ventilation the moment air turns bad and stops once it's fresh again (demand-controlled ventilation).
• Plug & Play — No Electrician: Plug your exhaust or fresh-air fan into the built-in AC socket (max 3A / 700W), set your CO2 thresholds on the front panel, and it works instantly. Zero wiring.
• Industrial NDIR Sensor: Accurate, drift-resistant CO2 measurement from 400–5,000 ppm — the sensor technology ASHRAE recommends for demand-controlled ventilation.
• Wi-Fi Remote Monitoring: Watch live CO2, temperature, humidity and fan status from any phone or laptop browser — no app to download. View trend graphs and export data to Excel.
• 3-in-1 Display: Large 128×64 backlit LCD shows CO2, temperature and humidity together on one screen.
• Made in India: Designed, engineered and manufactured in Meerut by Systellar Innovations, ISO 9001:2015 certified, with a 1-year warranty and local support.

How It Works — Fully Automatic:

• 1. Monitor: The NDIR sensor measures CO2, temperature and humidity every few seconds, shown live on the LCD.
• 2. Activate: When CO2 crosses your set limit (default 1,000 ppm), VentPlus switches on your fan through the built-in AC socket. An optional beeper can alert at 1,500 ppm.
• 3. Ventilate & Save: Once fresh air restores CO2 to your lower limit (default 800 ppm), the fan switches off automatically — saving energy and protecting air-conditioning costs.

All thresholds — Fan ON, Fan OFF and beeper alert — are fully user-settable from the 4-key front panel (ESC, UP, DOWN, SEL).

The Complete VentPlus System:

• Main Unit (Sensor + Controller + Wi-Fi): Houses the NDIR CO2 sensor, temperature/humidity sensors, backlit LCD, control panel and a built-in AC fan socket. Wi-Fi enabled for data upload and relay pairing.
• Wi-Fi Relay Unit (optional add-on): Controls a fan in a different room, communicating with the Main Unit over the internet — the two devices don't even need to share a Wi-Fi network. Ideal for large buildings and multi-floor installations.
• Remote Monitoring Website: A secure live dashboard with CO2 trend graphs, fan ON/OFF history and one-click Excel export — accessible from any browser, no app required.

Where VentPlus Is Used:

• Offices, IT parks & co-working spaces — beat the post-lunch slump, cut headaches and absenteeism, and hold ASHRAE-recommended air quality.
• Homes, apartments & bedrooms — automatic overnight ventilation for fresher air and better sleep, windows still locked.
• Schools & classrooms — a proven classroom CO2 monitor for CBSE, ICSE and international schools, protecting attention and learning.
• Mushroom farms — precise CO2 control for oyster, button, milky and shiitake cultivation at every growth stage (colonisation, pinning, fruiting).
• Greenhouses & polyhouses — dual-relay CO2 enrichment (fresh-air fan + CO2 generator) to hold the ~700–1,200 ppm sweet spot for 20–30% higher yields.
• Hydroponic grow rooms & grow tents — plug-and-play CO2 enrichment for vertical farms and indoor cultivation, no PLC needed.
• Hospitals, clinics & waiting rooms — CO2-based demand-controlled ventilation to lower infection risk and improve comfort.
• Gyms, yoga studios, banquet halls, restaurants & auditoriums — automatic fresh-air control for high-occupancy spaces.
• Army bunkers, barracks & defense installations — reliable 24×7 CO2 control in sealed underground spaces.
• Cold storage, warehouses, basements & parking — worker safety and controlled-atmosphere monitoring in confined spaces.
• Poultry farms, cattle sheds & animal housing — automatic exhaust control for broiler/layer sheds, hatcheries and dairy sheds.

A single unit covers roughly 100 sq m (about 1,200 sq ft) with moderate air circulation; larger or multi-room spaces simply add more units, each controlling its own zone.
