PENGEMBANGAN SISTEM AKUISISI DATA KELEMBABAN DAN SUHU DENGAN MENGGUNAKAN SENSOR DHT11 DAN ARDUINO BERBASIS IOT
Has been developed an acquisition system Â data of humidity and temperature by using DHT11 censor and Arduino. Data which have been read by censor of DHT11 then processed by Arduino andÂ then sent to a webserver that is thingspeak. To send data to the web server, used ESP8266 moduleâ€™s to access wifi signal of portable hotspot. Data of censor of DHT11 then presented in thingspeak with graph form. Temperature data read by DHT11 compared to data read by censor of thermocouple vernier. And then calculated value of error reference that is 1,73%.
