In the modern era of management, one of the biggest challenges is to manage a large stock at the warehouse with the latest technology. Warehouse Management systems may be standalone or cloud-based or integrated Enterprise Resource Planning based. In the warehouse, a manual or robotic system is used to check the status of stock. The proposed method is an innovative method to check the status of stored stock using the RF Attenuation system. Radio Frequency (RF) signals get attenuated due to many environmental phenomena such as reflection, refraction, diffraction, fading, scattering, and mainly due to the nature of the medium. The proposed Radio Frequency communication system consists of a 433MHz RF transmitter with 27 dBm transmitting power, a Radio Frequency receiver, and a Radio Frequency power meter. The research carried out to study the effect of the stock of storage items like cloths, books, and wheat grain inside a closed metal container on RF attenuation. It is observed that the RF signal gets attenuated is proportional to the stored stock. This study can be implemented in the warehouse to check the status of the stock where a manual or robotics systems fails.
