Sonar is a very common technique used in submarines and other underwater vessels. It uses sound propagation to detect objects in the water.

In this project, we have used ultrasonic sensor, servo motor connected to the microcontroller. The servo motor is used to rotate the radar system from 0 to 180 degree and the distance between the integrated system and the obstacle is calculated by the ultrasonic sensor.

The Processing IDE helps to draw a graph around the radar system and the obstacle detected by the sonar waves emitted from ultrasonic sensor is denoted by red marking.

]]> Voice Controlled Robot https://new.centrado-tech.com/product/voice-controlled-robot-3/ Tue, 20 Feb 2024 17:00:12 +0000 https://new.centrado-tech.com/?post_type=product&p=1114 Voice control robot is just a practical example of controlling motions of a simple robot by giving daily used voice commands.

In this project, the user gives specific voice commands to the robot through an Android app installed on the smartphone. At the receiving side, a Bluetooth transceiver module receives the commands and forwards them to the microcontroller on the robotic car.

The Microcontroller controls the movements of the robot according to received commands. The robot moves forwards, backwards, left and right, and stops according to the voice commands forward, backward, left, right and stop, respectively.

Arduino Bluetooth RC car app allows us to connect our smartphone to the Bluetooth embed on the Microcontroller. The App interface allows us to pair both the Bluetooth and control the car by  moving it in forward, backward, left and right directions.

]]> Renewable Energy-Solar cell https://new.centrado-tech.com/product/renewable-energy-solar-cell-3/ Tue, 20 Feb 2024 17:00:06 +0000 https://new.centrado-tech.com/?post_type=product&p=1096 Electricity is one of the primary needs in today’s world. We use lot of electrical appliances in day-to-day life. Electricity is usually non-renewable energy, in that case we can use solar energy, which is abundant in nature.

In this project we have discussed the characteristics of solar panels and how they can act as a battery source. We have also discussed the difference in series and parallel connections of the solar panels, considering the voltage gets added in series connection and remains same in parallel condition. Thus, Solar energy is a good replacement for non-renewable energies.

]]> Zener Diode https://new.centrado-tech.com/product/zener-diode-3/ Tue, 20 Feb 2024 17:00:06 +0000 https://new.centrado-tech.com/?post_type=product&p=1097 Zener diode is a semiconductor device consisting of a P-N junction which conducts the current in reverse direction when a certain specified voltage is reached. It has a reverse breakdown voltage which means it can continuously operate in a reverse-bias mode without getting damaged.

Hence Zener diode can act as voltage regulator, when they are reverse biased. When the input voltage fluctuates or whenever the voltage in the output changes due to variations in the load, Zener diode prevents the load from getting damaged.

]]> Electronic Voting Machine https://new.centrado-tech.com/product/electronic-voting-machine-3/ Tue, 20 Feb 2024 17:00:06 +0000 https://new.centrado-tech.com/?post_type=product&p=1108 The basic idea of Smart Electronic Voting Machine is to create an automated system that will help , eradicate fraudulent practices in the manual voting systems and older versions of electronic voting.

Here, in this project, a switch/push button is allocated for each political party. In the real time voting system, the voter will be required to show his Aadhar card as his identity proof. Here, we have used RFID card for identity and then each voter have to press their own passcode like OTP to proceed for choosing their preferred candidate from the panel of buttons. The final vote is then displayed onto an LCD for the satisfaction of voters. In the end, the result can be automatically calculated by pressing the result button.

]]> Smoke Detection Alarm https://new.centrado-tech.com/product/smoke-detection-alarm-3/ Tue, 20 Feb 2024 17:00:06 +0000 https://new.centrado-tech.com/?post_type=product&p=1109 A smoke detector is an electronic fire-protection device that automatically senses the presence of smoke, as a key indication of fire, and sounds a warning to the building occupants.

In this project, we have used MQ-2 gas sensor. It is a metal oxide semiconductor, which is a robust Gas sensor suitable for sensing LPG, Smoke, Alcohol, Propane, Hydrogen, Methane and Carbon Monoxide concentrations in the air.  We have also included a buzzer and an LED connected to the microcontroller.

The detector will detect the smoke and notify the user through the buzzer and red LED if the smoke density is above the safety limit.

]]> RFID Door Lock https://new.centrado-tech.com/product/rfid-door-lock-3/ Tue, 20 Feb 2024 17:00:06 +0000 https://new.centrado-tech.com/?post_type=product&p=1110 RFID stands for Radio Frequency Identification and it’s a non-contact technology. They are used for the purposes of tracking, access control, supply chain management, books tracking in libraries, tollgate systems etc.,

In this project we have used RFID card which has 2 components, the tag which authenticates the user and the reader, which will be implemented in the door. Then we have used 180 degree servo motor which is fixed at the back side of the door along with a 3D printed lock system.

]]> Smart Irrigation System https://new.centrado-tech.com/product/smart-irrigation-system-3/ Tue, 20 Feb 2024 17:00:06 +0000 https://new.centrado-tech.com/?post_type=product&p=1111 The basic idea of Smart irrigation system is to monitor the moisture level of soil and automatically irrigate the soil.

In this project, we have used soil moisture sensor connected to the microcontroller, which can sense the level of moisture content present in irrigation field. It has a level detection module in which we can set a reference value. In addition to this, we also have used a submersible water pump module attached to the motor driver.

When the reference value set for dryness of the soil is reached, it automatically initiates the motor pump to irrigate the soil till the wet moisture level of the soil is reached.
