Abstract
This paper presents an alternative peer to peer communication for the Internet of Things (IoT) using ESP32 microcontroller for indoor environments. This peer-to-peer communication is called ESP-NOW. The development is done using Arduino-ESP32 in the Visual Studio Code with Platform extension. Based on the experiment, the environmental sensing data can still be transmitted using the ESP-NOW protocol even with the lowest transmission power level. Thus ESP-NOW communication can be used in indoor environments but with a limited number of devices paired up together and depends on the surrounding environments confining in the indoor environments.
