This system monitors room air quality (CO2, temperature, humidity) and automatically controls ventilation (fan, exhaust, or air purifier) using IoT technology. It improves indoor air quality by activating the system based on sensor readings and allows remote control via a mobile app or web dashboard.
Components:
ESP32 / ESP8266 microcontroller
DHT11/DHT22 – temperature and humidity sensor
MQ135 – air quality sensor (CO2, NH3, etc.)
Relay module – to switch fans or purifiers
12V Exhaust Fan or Ventilator
Power supply – (Battery/Adapter)
Blynk / IoT Dashboard – for monitoring and control
Jumper wires, breadboard, PCB
How It Works:
Sensors collect air quality and climate data.
ESP32 processes the readings and decides when to switch the ventilation.
Fan is activated via relay if pollutants or temperature cross thresholds.
Real-time values and controls are accessible via smartphone using Blynk.
Applications:
Smart homes and offices
Hospitals and clinics
School classrooms
Server rooms or labs
Green buildings (energy-efficient design)
Dimension:
Length=20cm
Width=10cm
Height=10cm

IoT Based Smart Ventilation System Project
-
Order Processing Time:
- All project orders are processed within 2-3 business days after payment confirmation.
- After processing, the development of your project will begin. We require a minimum of 10-15 days to complete and prepare your project for shipment. However, please note that the delivery time is an estimate and may vary depending on project complexity and component availability.
-
Delivery Timeframe:
- While we strive to deliver your project within the specified timeframe, there is no guaranteed delivery date. The actual delivery time may be shorter or longer depending on various factors, including shipping delays, customs clearance, and unforeseen technical challenges.
- We will keep you informed of your project's progress and provide updates on the estimated delivery time as needed.
-
Shipping and Delivery Charges:
- Delivery charges are additional and are not included in the project price. The shipping cost will be calculated at checkout based on your location and the chosen shipping method.
- Customers are responsible for any customs duties, taxes, or fees that may be applicable in their country.
-
Order Cancellations:
- Due to the customized nature of our projects, orders can only be canceled within 24 hours of placement. After this period, the order is non-cancellable as work will have already begun.
-
Returns and Refunds:
- As these are custom-built projects, we do not accept returns or offer refunds unless the project is defective or significantly not as described.
- If there are any issues with your project upon delivery, please contact us within 7 days to resolve the matter.
-
Technical Support:
- We provide basic technical support for the first 30 days after delivery to help you set up and operate your project.
- Extended support and customization services are available at an additional cost.
-
Disclaimer:
- We are not responsible for delays caused by external factors beyond our control, including but not limited to shipping carrier delays, natural disasters, or government restrictions.
- By placing an order, you agree to the terms and conditions outlined in this policy.
