This research was used of temperature humidity sensor DHT-11 to detect level of humidity and temperature changes inside the room. With Comparative analysis of the hardware data with readings from the HTC-2 device revealed minimal total error rates, with an average of 1.594% affirming the reliability and consistent performance of this device. The data and information from DHT-11 sensor was transferred by ESP32 using Arduino IDE Program and analyzed graphically on Google Spreadsheet platform using Apps Script.enSOCIAL SCIENCES::Statistics, computer and systems science::Informatics, computer and systems science::Information technologyArticle3222111004NIDN0019078903KODEPRODI20406#TEKNIK ELEKTRONIKA MANUFAKTUR
