Health Monitoring System using 7-Segment Display & Atmega Microcontroller

Image
  This health monitoring system is a very useful system, which can be used to monitor the health parameters of the patient. This system continuously monitors the heart rate and the temperature reading of the patient. In this health monitoring system project, we use two 7 segment modules to display the parameters, as the display has a greater viewing distance. We can select the upper limit and lower limit for the temperature and heartbeat as well. While monitoring, if the temperature is increased beyond the set high limit or is decreased below the set limit then the buzzer sounds and the load turns off. Similarly, when we remove the heartbeat sensor and system detects low heartbeat and buzzer buzzes and the load is switched off. This buzzer can help the patient’s well-wishers to take action in an emergency. When the temperature and heart rate come into control the bulb turns on and the alarm gets off

Sound Activated Lamp

Image
  We all strive to save energy where we can, especially when those festive lights keep your home’s power meter seemingly spinning out of control. A great way to save energy is to be smart about it. The  Sound-Activated Lamp  project demonstrates this by turning on lights when sounds are detected (e.g., in the presence of people), and then automatically turns off the lights after a period of no sound. This project includes two C modules: the first module defines a kernel-level driver that sets up an IRQ handler for detecting sound. The second module contains the main() loop that repeatedly reads the sound value from the lamp driver and toggles the lamp accordingly. Using this project, you can automate the activation of lights in certain areas of your home based on occupancy, all while learning about kernel-level Linux code.

Smart Home Control

Image
  While voice control is convenient, so too is controlling your smart home devices via your smart phone. The  Home Control on QCA402x  project does just that using a  Qualcomm QCA4020  SoC to control a smart bulb, smart lock, and smoke detector via a mobile app over Bluetooth Low Energy. The project includes a home automation application written in C that runs on the QCA4020. A smart lock (servo motor) is wired to the QCA4020 and receives  PWM signals  from the application to lock or unlock the door. A smoke sensor is also wired to the QCA4020, while a thread in the application polls the sensor every 30 seconds to determine if smoke is detected. The smart light bulb is connected wirelessly to the QCA4020 over Bluetooth Low Energy. This project also includes an Android GUI application that runs on a smart phone to control the smart light bulb and lock. The application sends the corresponding commands to the QCA4020 over Bluetooth Low Energy as the user ...
