The reason that it is called relative humidity is because the higher the temperatures are the higher the capacity of the air to hold water.
Temperature and humidity control system project.
Relative humidity control is a big deal as you are about to see.
As a rough rule of thumb you could say that for every 18 f rise in temperature the air s ability to hold water doubles.
This is a very simple project to build a temperature humidity controller with 2 relays to control a hot source and a humidifier.
Temp humidity chart using websockets and highcharts.
In this project i used an arduino uno and a dht11 sensor combined with a lcd potentiometer button and relays.
172 temperature projects using websockets on one arduino mkr1000 connected to wifi i send temp humidity data to a chart setup on highcharts.
It measures both temperature and humidity of the environment.
The system will get temperature from the dht 11 sensor.
The dht11 sensor is heart of the project which may be placed at the middle of any four sides of incubator inside but away from the bulb or humidity inlet tube.
This system uses a waterproof humidity and temperature probe to monitor environmental parameters and an arduino uno connected to 5v relays to control the activation of a humidifier and a cooling fan.
If you made lot of unnecessary holes or if humidity or temperature is escaping too fast you may cover some of the holes using electrical or duct tape.
