Node MCU is an open-source Lua based firmware and development board specially targeted for IoT based Applications. It includes firmware that runs on the Wi-Fi SoC from Expressive Systems, and hardware which is based on the module. It refers to the firmware rather than the associated development kits.
The smart grid is adding smartness to the electric grid by adding smart devices like wireless sensor networks that provide real time information quickly. Transmission lines and distribution system connect power generation plant to consumers. The power generated at source is at low voltage and it is stepped up to high voltage and transmitted to consumer.
Data security concentrates on providing security to the stored data in cloud storage but concerns less on securing the data while it is being transferred. The data becomes prone to intruder attacks while being transferred.
It is effective and efficient for users to navigate using precise speech instructions. Overall, the developed system will make the visually impaired people and their guardian’s feel much safer and confident.
It is design of a system to ensure the rider wearing the helmet properly while the complete journey details are recorded on the server. The system records the helmet status, speed of the vehicle, accident status and the location of the vehicle all through the time the vehicle ignition starts.
The system is designed to use in hospitals for measuring and monitoring various parameters like temperature, ECG, heart rate, blood pressure. The results can be recorded using Arduino. It is useful for monitoring health system of every person through easily attach the device and record it.
It accesses the parking slot availability over the internet. This system can completely automate the smart parking system. It controls the complete process and sends the parking availability and time information, so that it can be monitored from anywhere in the world using this platform.
A system that puts forward a smart health monitoring system that uses sensors to track patient health and inform to the respective doctor in case of any emergency issues. The system is developed for patients need to be periodically monitored. It uses temperature as well as heartbeat to keep track of patient health.
The system that gives prior information on the filling of the bin that alerts the municipality so that it can clean the bin on time and safeguard the environment. This system maintains a dry waste and a wet waste separately. It helps to reduce the overflow of the garbage bin cities and this keeping the environment clean.
It provides a smooth flow for the ambulance to reach the hospitals in time. The aim of implementing which control mechanically the traffic lights in the path of the ambulance. It is controlled by the central unit and also controls the traffic light according to the ambulance location and thus help reach the hospital safely.
It providing a better and secure system to the passengers, we have proposed a design of baggage tracking and handling system using smart RFID tags and IoT. The system provided ensures less consumption of time, security for baggage and is economical hence provides customer satisfaction.
The integration of the Arduino provides the meter reading system with some automatic functions that are predefined. It provides data to optimize and reduce the power consumption.
It is considered as a tool for the acquisition of muscle activity is recorded and analyzed, then sent to remote service with the help of IoT concepts, where things peak been used where it helps in the telemetry of the obtained signals using the cloud and sensor input is given to Node MCU.
It deals with to keep track of the soldier parameters such as temperature, breathing and heart rate. Node MCU are used in designing the soldier monitoring system, can be explained as it is used for monitoring physiological information.
It is an innovative, smart & protective Cradle System to nurture an infant in an efficient way. This system considers all the minute details required for the care & protection of the Baby in the cradle.
The parameters automatically measure the infant’s weight and temperature to determine the condition of the infant. It is operated through IoT which can facilitate paramedic to monitor the infant’s situation through internet network that can be accessed via web or Android.
The system performs water quality monitoring and Regulated water supply operation. It calculates and analyze in the sensor value to the water purity and sent the alert email to the authorized person by using the IoT Technologies.
It is proposed to develop an embedded based remote water monitoring and theft prevention system by recording the flow rates at the user end. The monitoring of water resources for these enterprises can prevent the occurrence of stealing water and leaking water effectively.
Health monitoring devices leads to a drastic change in medical sphere as it ensures the safety of the patients and even helps in reducing the stress of doctors and nurses. This system measures the weight of the saline bottle with the help of a load cell and then using an automatic alerting and indicating device sends the alert signal.
Smart street light automates by using LDR, InfraRed sensors (IR), which means if IR sensor detects the person, it will turn ON the lights otherwise the light gets OFF. This will reduce the power consumption and efficiently use power of the street lights. The sensor values will automatically upload to the Thing speak cloud.
The system is to develop a smart notice board that display message and sent the user through mobile phone. It is designing a simple, user-friendly system, which receive and display information in a particular manner with respect to date and time which help the user to keep the track of notice every day.
The problems can be solved by using Internet of Things based power management system which keeps track of consumer loads in order to accurate billing and a way to save the wastage of power by using some threshold values. It improves the power levels and smart billing system with the help of smart meters and smart grids.
A sensor is interfaced to Node MCU detects the temperature and humidity produced from the fire. It is taken into consideration and analysis is made to detect fire. When it is detected, an email triggered with the sensor values and the fire is predicted.
It protects the verification process by verifying transactions in the secure execution environment and keep the local block chain unreadable through encryption. The result of the experiment shows that it has little impact on the system.
IOT is system of related sensors, computing and digital devices spread across the globe over the internet which can communicate to share and transfer information using unique id which is assigned to each and every device. It provides a reliable and user-friendly application for easy to use and monitor the electrical devices.
The sensor can be tracked in temperature, light intensity, fire sensor, and gas level. It is collected and stored on the microcontroller. The sensor value means the motor will stop and the buzzer will continuously blow. After the application of program, Node MCU will get execute.
Monitoring the farm for disease detection is labor intensive and time consuming. By using Node MCU, it able to detect plant diseases more efficiently which require manual operations to obtain the data for analysis. Based on an IoT platform for soil cultivation, it develops and utilize non-image devices to detect rice blast.
