Has been developed an acquisition system  data of humidity and temperature by using DHT11 censor and Arduino. Data which have been read by censor of DHT11 then processed by Arduino and then sent to a webserver that is thingspeak. To send data to the web server, used ESP8266 module’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%.
