Alive Human Detection Robot using PIR sensor

Modern technology has paved the way for the construction of tall buildings and houses, which increases the risk of life loss during both natural and human-made disasters. To address this issue, we propose a recommended approach involves using a robot equipped with sensor technology to locate and determine the status of humans. The proposed solution is a robot based on passive infrared sensors (PIR). The robot is equipped with a set of sensors, including the micro controller using ultrasonic and PIR sensors, to detect signs of life from humans. If the person is found to be alive, a buzzer is activated. The robot then shares the person's location through a global positioning system(GPS) module, sending this information to the receiver via message. This way, timely assistance can be provided to individuals in need, potentially saving lives in critical situations. However, in harsh weather conditions, people may be stranded at various locations, making it challenging to find and assist them. The robot is operated via a Bluetooth module and utilizes an ultrasonic sensor to navigate autonomously
