Story

Mr. Abhishek Maurya, founder of Yarana IoT Guru, wanted to build a smart home sensor system that could fit into a compact space.

He discovered the Arduino Nano ESP32 — a tiny yet powerful board packed with Wi-Fi and Bluetooth features.

Within just a few hours, he developed a mobile-controlled lighting system and a temperature monitoring setup, fully powered by Yarana Smart Home Technology.

💬 “It amazed me — a tiny board doing everything a full ESP32 Dev Board can do!”
