1. Introduction: Impaired driving due to alcohol consumption remains a critical concern, posing a significant threat to road safety. To address this issue, we present an Alcohol Detection System designed to detect the presence of alcohol and raise awareness about the risks of impaired driving. By utilizing an Arduino board, an alcohol sensor module, and incorporating visual and audible indicators such as a red LED and a buzzer, our system aims to promote responsible driving practices and prevent accidents caused by alcohol impairment. 2. Working: Step1: Hardware Setup : Connect the alcohol sensor module to the Arduino board following the provided pinout or wiring diagram. Wire the red LED and buzzer to the appropriate digital pins on the Arduino. Step2: Sensor Data Calibration: Calibrate the alcohol sensor module according to the manufacturer’s instructions to ensure accurate detection. Adjust the sensitivity of the sensor to the desired threshold for dete...
1. Introduction: In today’s fast-paced world, ensuring road safety is of paramount importance. To address this concern, we present a project that utilizes Arduino, GSM (Global System for Mobile Communications) module, and GPS (Global Positioning System) module to develop a Vehicle Accidents System capable of detecting sudden accidents and promptly notifying authorized individuals for immediate assistance. Our project focuses on leveraging gyroscope and accelerometer sensors in conjunction with Arduino microcontrollers to detect abrupt changes in vehicle motion. These sensors provide precise measurements of angular velocity and linear acceleration, enabling us to identify collision events and classify them as potential accidents. The integration of Arduino, GSM module, and GPS module empowers the system to respond swiftly and efficiently in emergency situations. When an accident is detected, the system triggers a series of actions to notify preconfigured authoriz...
1. Introduction: Welcome to the "Wireless Notice Board with NodeMCU" project, an innovative solution designed to modernize traditional notice boards and streamline the process of sharing information in public spaces. By harnessing the power of wireless technology and the NodeMCU microcontroller, this project aims to revolutionize communication by providing an efficient and flexible means of displaying messages and announcements. In today's fast-paced world, effective communication is vital, whether it's for conveying important announcements, displaying schedules, or sharing general information. Traditional notice boards often require physical interaction and manual updates, which can be time-consuming and inefficient. The "Wireless Notice Board with NodeMCU" project addresses these challenges by leveraging wireless connectivity to enable remote updates and real-time information dissemination. 2. Working: Step1: Wireless Connectivity : Configure the Nod...
