Implementation of Monitoring System and Prediction of Room Humidity for Orchid

Orchid plants are one of the ornamental plants that are much favored by humans because they have an attraction that is very beautiful flower parts. This causes many people to try to make the cultivation of orchids themselves. But behind the beauty of orchid plants, very good care is needed because orchids need the right moisture content and humidity in the room in order to grow well. The humidity that orchids need is 50% - 80% during the day. By using the help of the ESP8266 module and the DHT-11 Temperature Sensor, it can help to monitor orchid humidity and predict the humidity obtained in the next time. Also added a relay, and Mist Maker to help increase humidity. If the results of the prediction are less than 50%, the relay will automatically flow electric current to the mist maker and can help raise the humidity back to 50%. Predictions are obtained from the results of experimental humidity measurements carried out for 24 hours. The results of the predictions obtained are quite accurate because the difference with the humidity presentation differs by about 0.2 from the humidity measurement results obtained.
