The development of technology in the field of electronics is growing rapidly. Technology can increase the efficiency of human activities. This research discusses the design of temperature monitoring devices in air-conditioned rooms that can be monitored from a close distance from the LCD (Liquid Crystal Display) and remotely using IoT (Internet of Things). The hardware used is called ESP8266 temperature sensor called DS18B20. This software uses like the Thingspeak web, virtuino Android application. The results of test data for temperature monitoring devices are sent every minute and can be displayed on the LCD and from Android-based smartphones using IoT technology.
