HEART BEAT PROJECT USING ATMEGA328

HEART BEAT PROJECT USING ATMEGA328P

PROJECT DESCRIPTION:

Heart rate, body temperature and blood pressure monitoring are very important parameters of human body. Doctors use various kind of medical apparatus like thermometer for checking fever or body temperature, BP monitor for blood pressure measurement and heart rate monitor for heart rate measurement. Here we have used a heartbeat sensor module which senses the heartbeat by the pulse in ear, Heart rate ear clip kit contain a ear clip and a receiver module. The heart rate measure kit can be used to monitor heart rate of patient and athlete. The result can be displayed on a screen via the serial port and can be saved for analysis. The entire system has a high sensitivity, low power consumption and is very portable.

This simple project will allow you to visualize your heart rate result through a Bluetooth connection with an android moblie phone using hc-06 Bluetooth module

COMPONENT:

Atmega328p
Heart rate ear clip
LCD 16X 2
Bluetooth module

SOLAR CHARGE CONTROLLER USING PIC16F876A (ZERO DROP)

ZERO DROP SOLAR CHARGE CONTROLLER

PROJECT DESCRIPTION:

This circuit degisn is called ‘zero drop solar charger’ because it doesn't have any diode drop of 0.7v. This is a mosfet based design which has very negligible voltage drop of 0.05v or less which means the loss is very less, ideal for solar applications.

Since the drop is less, the losses are negligible so the efficiency achieved is > 99.5%

In this the two n channel mosfets are connected in such a way that their sources become common and the drains will be connected to the negatives of battery and solar panel respectively and the gate will be triggered by the microcontroller (pic16f876a).

The positives of solar panel and battery will be joined directly and the circuit was powered from that joint.

When the solar power was present the circuit gets activated and micro-controller will pumps the signals that to trigger the gate of mosfet, when the gate was triggered the negative voltage will flow through the mosfet and then the battery will be charged through solar panel.

Specification:

Voltage 12v - 96v

Current 10A - 60A

Efficiency > 99.6%

Protection against : Panel reverse

Battery reverse

Battery Overcharge ( full charge cut - off level is settable )

Charger monitor - 16 x 2 lcd display

Other feature - Opto - Coupler output for Charging signal to external circuits (like inverters)
