In industries, there will be various loads to be operated and these loads are to be operated at some specific intervals according to our requirements and also based on the device’s constraints. For these purposes, a person should be employed to monitor the status of the loads. But there may be chances that the person may forget to operate these loads. And also it is not an easy task for a person to operate these loads manually as these loads run with high currents and high power consumption. This project gives the best solution for electrical power wastage. Also the manual operation is completely eliminated. This project does this application using wireless concept. One of wireless communication system is RF (Radio frequency) communication system as it is very cheap and very easy to implement.
This project is not only limited to industrial applications but can also be extended to domestic purposes as home appliances controlling using RF. The home appliances can be switched on/off using this RF concept without actually going near the switch boards or regulators.
The loads like lights, motors, heaters, power controlling system and also current through the loads can be controlled in this project. We can control all loads at a time from one place (control room) without connecting any physical wire between loads and control room. The RF modules used here are 2.4GHz UART . Switches are provided at the transmitter end, to control the loads which are connected at the receiver side.
The switches are interfaced to the RF transmitter. The encoder continuously reads the status of the switches, passes the data to the RF transmitter and the transmitter transmits the data. At the receiving end, the RF receiver receives this data converts the single bit data into 8-bit data and presents it to the microcontroller. Now, it is the job of the controller to read the data and perform the corresponding action i.e., switch on/off corresponding load or vary the speed according to the user requirement.
