Abstract

This paper reports the design and implementation of a contactless, hand gesture–based wireless control interface for basic household appliances. A PAJ7620 gesture recognition sensor, integrated with a transmitter ESP32, detects four predefined gestures and sends control commands via ESP-NOW to a receiver ESP32. The receiver actuates a lamp indicator (LED) and a 5 V DC fan through a relay module. Custom PCBs and 3D-printed enclosures were developed to improve integration and portability. Functional testing verified correct gesture-toactuation mapping, stable device-to-device communication, and state retention between commands. The proposed approach reduces reliance on touch and speech input, making it suitable for noisy environments and for users who benefit from contactless interaction in home and care settings.
