Prototype An ESP32-Based Room Humidity and Temperature Controller With IoT

This research was conducted to design a room air humidity and temperature control device to complement the features of an economical air conditioner (AC), which can automatically regulate humidity and temperature. So that the ideal level of humidity and temperature is achieved under the ministry of health’s provisions on comfort and air quality in the room, namely 40-60% Relative Humidity (RH) and 18-26 oC. To realize this, the AM2301 sensor is used to read the temperature and humidity in the room. Then the readings from the AM2301 sensor will be processed by ESP32 and then displayed on the OLED display and in the Blynk application, with infra-red LED as an AC controller and ultrasonic mist maker as a room humidity tool. Based on the results of the tests, this design has succeeded in becoming an additional feature of economics that lacks the features of air comfort and health. It is time to reach the ideal humidity level of 40-60% RH on average within 1 hour and 16 minutes.
