Humidity in the computer laboratory must be regulated to remain at an optimum 50%. If the humidity is low, it allows static electricity to build up and causes damage to sensitive electronic components. Similarly, high humidity of over 70% causes rusting of the metallic parts of the computer system.
To eliminate low humidity, place humidifiers in the room, while high humidity can be controlled by installing dehumidifiers in the room.
