Non invasive Measurement of cholesterol and haemoglobin using ppg
Traditional methods for measuring cholesterol and hemoglobin levels are invasive, requiring blood samples and laboratory processing, which may be inconvenient for continuous or remote health monitoring. This project proposes a non-invasive health monitoring system that estimates cholesterol and hemoglobin levels using Photoplethysmography (PPG) signals, combined with machine learning (ML) algorithms. The system is built using a NodeMCU microcontroller and integrates an SpOâ sensor and heart rate sensor to capture real-time PPG waveforms. These signals are analyzed using a Flask-based server, where ML models trained on clinical datasets predict the userâs cholesterol and hemoglobin levels with reasonable accuracy. The results are displayed on a secure web dashboard for remote health monitoring. This contactless solution supports continuous assessment without needles or lab intervention, making it ideal for home use, remote clinics, and chronic care settings. It provides an accessible, low-cost alternative for routine health diagnostics while promoting user comfort and reducing healthcare burdens.
Voice Controlled Home Automation
The evolution of smart homes has driven the need for more intuitive and hands-free control systems to enhance user convenience, accessibility, and energy efficiency. This project proposes a Voice Controlled Home Automation System using IoT and Flask, enabling users to operate home appliances through voice commands. At the core of the system is an ESP32 microcontroller integrated with a microphone (mic) module for capturing voice inputs. These inputs are processed through a Flask-based web application, which interprets commands and triggers the corresponding actions. A relay module is used to control devices such as a light bulb and a motor with wheel, simulating home appliances like fans, lights, or curtains. Upon recognizing specific voice commands, the system actuates the appropriate relay switches to turn appliances ON or OFF. The entire setup supports remote control and real-time feedback through an IoT dashboard, offering both automation and user-friendly interaction. This system demonstrates a low-cost, efficient, and scalable approach to smart home management, particularly useful for elderly or differently-abled individuals.
smart street Light
Conventional street lighting systems consume substantial energy and often remain powered regardless of environmental lighting conditions or pedestrian activity, leading to energy wastage. To address this issue, this project proposes an IoT-based Smart Street Light System designed to optimize energy usage by dynamically controlling street lights based on environmental and motion conditions. The system employs a NodeMCU microcontroller to collect data from an array of sensors, including an LDR (Light Dependent Resistor) sensor to detect ambient light levels and IR (Infrared) sensors to detect human or vehicular movement near the light pole. Based on sensor inputs, the system intelligently turns the LED light on or off via a relay module. A stick-mounted setup simulates real-world deployment of the street light pole. When ambient light is sufficient (e.g., during the daytime), the street light remains off, while in low-light conditions, it turns on only if movement is detected, thus conserving energy. This smart lighting solution represents a cost-effective and sustainable advancement in urban infrastructure, promoting intelligent energy management and public safety.

IOT Based Garbage Monitoring System
In modern urban environments, inefficient waste management continues to be a major environmental and logistical challenge. Overflowing garbage bins lead to unsanitary conditions, attract pests, and degrade public hygiene. To address this issue, this project proposes an IoT-Based Garbage Monitoring System that enables real-time monitoring of waste levels in garbage bins using ultrasonic sensing and Wi-Fi-based communication. The system is built using a NodeMCU (ESP8266) microcontroller connected to an ultrasonic sensor, which is placed inside the garbage bin to measure the fill level by calculating the distance between the sensor and the garbage surface. When the bin reaches a pre-defined threshold (e.g., 80â90% full), the system activates an LED indicator to signal that the bin needs to be emptied. Simultaneously, the NodeMCU sends the fill level data over Wi-Fi to a centralized IoT server or web dashboard, allowing municipal authorities or private waste collection agencies to monitor multiple bins remotely in real-time. The system is designed using minimal hardware, including the ultrasonic sensor, LED, NodeMCU, wiring, and a compact PCB board to ensure low cost, ease of installation, and scalability.

Energy Efficient Wireless Communication for IOT Enabled Greenhouses
With the rise of smart agriculture, greenhouses are increasingly adopting IoT technologies to monitor and control environmental conditions for optimal plant growth. However, continuous wireless communication between sensors and cloud platforms can lead to excessive energy consumption, especially in off-grid or solar-powered systems. This project presents an Energy-Efficient Wireless Communication System for IoT-Enabled Greenhouses, incorporating selective data transmission and a Flask-based web server for real-time monitoring and control. The system is developed using a NodeMCU (ESP8266) microcontroller, interfaced with a soil moisture sensor, temperature sensor, and LDR sensor to monitor key environmental parameters such as soil hydration, ambient temperature, and light intensity. Instead of transmitting data continuously, the NodeMCU uses a threshold-based approachâcommunicating with the server only when there is a significant change in sensor values or when readings cross critical limits. This approach reduces power consumption while maintaining accurate environmental insights. Collected data is sent via Wi-Fi to a Flask-based server, which receives, stores, and visualizes the sensor values on a web dashboard. The dashboard allows remote users to track real-time and historical data, and to configure alert thresholds or control strategies. Flask provides a lightweight yet powerful backend framework that supports future expansion, integration with databases, and data-driven decision-making tools. By combining intelligent communication protocols, real-time sensing, and a responsive Flask web interface, the system delivers a low-power, cost-effective, and scalable solution for smart greenhouse environments.
