Low-Cost Wireless Data Transmission System for Industrial Applications

This paper demonstrated an economic, reconfigurable, portable, and precise radio frequency (RF) based wireless data transmission system in process industries in the domain of public frequency band. This paper highlights the new way of a wireless communication system using commercially available RF transmitter and receiver. In this proposed system, we may connect five sensors simultaneously for transmission purpose. Sensor output data in the range of 0–5 V are taken in this work and this time-varying analog data is converted to 8-bit parallel data. This 8-bit parallel data is then transferred through two transmitter modules. At the receiver end, two receiver modules receive this 8-bit parallel data. After obtaining 8-bit parallel output data, we use some suitable equation to get equivalent decimal value ranging from 0 to 255, where 0 represents 0000 0000 and 255 represents 1111 1111 and based on this, we can easily calculate the equivalent analog output data.
