IoT or the internet of things is characterized as a forthcoming innovation that empowers us to create worldwide networked machines and also the devices that can be helped for exchanging of communication. As we all know that the real-time application has been increasing day by day, the smart connection also had increased. Rapid population growth led to the increase in global life expectancy and the advance of technology, paving the pathway for the creation of age-friendly environments.
As we all know wireless communication systems operate on antennas for effective reception of signals. It is quite necessary to properly position the antennas in the direction of the transmitter for effective wireless communication. So here we propose an IoT-based antenna positioning system that allows for the remotely positioning of antennas based on IoT. In this system, the sensors and motors will be mounted on the antenna to detect its direction and its direction will be changed by motors using IoT. When the direction of a transmitting station changes over time, the antenna direction must also be changed accordingly. This system will help in monitoring antenna direction and transmitting new coordinates to position the antenna. This system appropriately positions the antenna accordingly. So basically using this system we can wirelessly position antennas in the desired directions using IoT.
OBJECTIVES OF THE PROPOSED SYSTEM:
- To Build a positioning antenna device that can be controlled from a remote location
- To position the antenna to the exact angle to receive maximum signal of a specific frequency,
- To adjust the antenna position through a simple software.
So here we are giving a project on an IOT based antenna positioning system that allows for the remotely positioning of antennas based on IoT. The method that is used here to control the antenna’s position is by using Node MCU and Stepper motors. Here, in this system sensors will be mounted on the antenna to detect its direction and its direction will be changed by motors using IoT. The Blynk app acts as a remote and is used to send the signal to the MCU through the internet. The project helps to control the antenna’s position by the user’s command
Here, we propose an antenna positioning system that enables antennas to be placed remotely over IoT. Because the position of the transmitting station changes over time even the position of the antenna should be changed accordingly. This is used by measuring the degree of command from remote and input to drive the motor at the desired degree.
. The system mainly comprises two parts :
- . The circuit of antenna and motor control.
- The Blynk app for user commands.
The circuit installed consists of various components such as MPU6050, Stepper motors interfaced with NodeMCU. The NodeMCU controller is responsible for positioning the motors. Depending upon the current reading of the accelerometer, the controller takes input from the user through the Blynk app via wifi module and motors move to the intended position. As a result, the user will receive the current position of the antenna, and the positioning of the antenna will be done according to user commands. The location of the antenna, i.e. tuning, is very critical for having regular satellite transmission signals. The antenna has to be located at a proper angle to get the best signal possible. Remotely controlling software improves advanced technology.
- NODE MCU:
Node MCU is a 32 pin microcontroller IC with an inbuilt WIFI module. All the components of the system are interfaced with this microcontroller. It is responsible for the functioning of the system. The Latest NODEMCU Wireless IoT Board was designed based on an integrated chip specifically to fulfill the needs of a new connected world. This Module is capable of either hosting an application or offloading all Wi-Fi networking functions from another application processor. This wireless module is completely addressable over SPI and UART protocols. As a result grants permission to connect your sensors or project directly to it through its GPIO.
- MPU-6050 GYRO SENSOR:
MPU-6050 is a sensor based on Micro Electrical Mechanical System (MEMS) technology. In this sensor module, the accelerometer and the gyroscope are embedded in a single chip using the I2C protocol to communicate, which helps to measure the acceleration, voltage, orientation, displacement, and many parameters of a system. An onboard Digital Motion Processor in this module is used to process the 6 axis fusion algorithm to provide a complete 9 axis motion fusion output by accessing the external magnetometer.MU-6050 is a low-cost and highly accurate sensor with an I2C bus.
- STEPPER MOTOR:
The motor rotates when it receives the signal from the NodeMCU. The speed and the direction of the motor can be changed as we change the rate of the input signal. The motor rotates clockwise or anticlockwise with a 90-degree step angle.
- STEPPER MOTOR DRIVER:
The Driver IC receives the signal from NodeMCU and transmits the signal to motors. According to the signal, the motors can be driven in any direction.
- WiFi MODULE:
ESP8266 Wifi Module AP & Station Remote Serial Wireless IoT Board designed based on an integrated chip specifically to fulfill the needs of a new connected world. It can handle all the necessary overhead for communicating with your network, such as TCP/IP stack and communicating with your 802.11 networks.

- Can identify different types of signals
- Can increase the range of detection
- Can adjust antenna angle to accurate level
- Cost effective
- Highly reliable
