Abstract:The proposed system "ultrasonic radar for the object detection, distance and the speed measurement” employs an ultrasonic module that includes an ultrasonic transmitter and receiver along with the Arduino Uno. It operated by transmitting 40 kHz frequency pulse which is not audible to the human ear. Module rotate with step angle of the stepper motor with specific angle for a specific time interval, microcontroller receive an echo signal back as response of the transmitted signal by transmitter and the distance between the object and system is measured by calculating time interval taken by the signal to transmit and the echo reception. Whereas the detected signal is shifted toward the module or away from the module which give the information about the speed of that detected object which is shown on PPI DISPLAY.

Abstract:These days we have an increased number of heart diseases including increased risk of heart attacks. Our proposed system users sensors that allow to detect heart rate of a person using heartbeat sensing even if the person is at home. The sensor is then interfaced to a microcontroller that allows checking heart rate readings and transmitting them over internet. The user may set the high as well as low levels of heart beat limit. After setting these limits, the system starts monitoring and as soon as patient heart beat goes above a certain limit, the system sends an alert to the controller which then transmits this over the internet and alerts the doctors as well as concerned users. Also the system alerts for lower heartbeats. Whenever the user logs on for monitoring, the system also displays the live heart rate of the patient. Thus concerned ones may monitor heart rate as well get an alert of heart attack to the patient immediately from anywhere and the person can be saved on time.
