An Embedded System based Curtain Controlling Unit using NRF Module

With the growing interconnectedness and intelligent automation, the 21st century is seeing a fast change in technology, industries, and practices. The concept of “interconnectivity” first appeared in the context of intelligent control systems, which promoted interactions and communication between technology, sensors, and people. Numerous real-world applications for these systems exist in the industrial sector, home automation, online banking, and other industries. This study proposes a novel embedded system based curtain controlling unit using NRF module in response to the quickly expanding automation. The proposed system uses a NRF24L01 transceiver and an Atmega328p microcontroller to communicate via GPSK modulation. By pressing the switch on the rotary encoder, the user may control the motors (which are linked to the curtains). Above the OLED display, the curtain status is displayed. Given that the system employs a small chip CPU and a NRF24L01 transceiver using GPSK modulation for transmission, it is most likely designed for enabling low-power and wireless communication. This might be helpful in situations where running wires is difficult or impracticable in the areas like Auditoriums, Hospitals and old age homes, where mobility of humans remain as a major challenge.
