Automatic Humidification System – Mechanical Projects

SYNOPSIS

A humidifier is an appliance that increases humidity in a single room or throughout the home. Humidifiers are commonly used to humidify a single room and whole-house or furnace humidifiers, which connect to a home's HVAC system to provide humidity for the entire home. The humidifier should generally be turned off during the summer months if air conditioning is used; Air conditioners work partially by reducing indoor humidity. The main parts used in this project are sprayer, water tank, water solenoid valve and humidity sensor.

This design can protect wooden objects, antiques and other furniture that may be sensitive to damage from excessively dry air.

WORKING PRINCIPLE

A water tank is placed on a base structure at a certain height. The water tank outlet is connected to a water solenoid valve. The water solenoids output is connected to the sprayer. Air can pass into the sprayer. The air flow is controlled with the help of an air solenoid valve. A humidity sensor is attached to the humidifier configured to detect the humidity level in the room. Water and air are mixed in the sprayer and the water and air mixture is sprayed through the nozzle. This happens when the humidity in or around the room drops below the limit. When a certain threshold is exceeded in the room, the humidity sensor issues a signal to the control unit. This control unit controls the operation of the sprayer. As soon as the signals are received from the sensor, the control unit activates or deactivates the spray gun. This process increases the humidity level when ambient humidity is low.
