III. PROBLEM AND SOLUTION

In India, the threat of terror attacks and natural disasters like earthquakes poses significant challenges to public safety and disaster management.

Introducing the Spy and Survivor Robo system offers a viable solution to mitigate these risks and enhance survival rates. This innovative device operates through a radio frequency system, providing controlled mobility within a specified range. Equipped with wheels, the robo can navigate diverse terrains, aiding in swift response and rescue efforts during crises.

Given the inadequacies in current disaster management practices, there is a pressing need to develop systems that minimize losses and maximize efficiency in handling such situations. Whether it's natural calamities such as earthquakes and tsunamis or technical disasters like building collapses and gas leaks, the Spy and Survivor Robo stands poised to revolutionize disaster response by optimizing both internal and external resources for effective management and mitigation of risks.

The MQ-2 gas sensor utilizes SnO2 as its gas sensitive material, which exhibits low electrical conductivity in clean air. However, when combustible gas is present in the surrounding air, the sensor's electrical conductivity rises in correlation with the concentration of the combustible gas. This change in electrical conductivity can be harnessed to generate an output signal through the implementation of a straightforward circuit.

Upon connecting the VCC and GND wires, the module's Power LED illuminates, indicating proper power supply. It is advisable to allow the power supply to preheat for a minimum of 2 minutes before usage to ensure optimal performance. While slight heating is expected due to the presence of a heating wire inside the sensor, excessive overheating should be considered abnormal. Under normal conditions, when there is no presence of gas or the gas concentration remains below the preset threshold, the digital interface D0 outputs a high level, and the voltage of the analog interface A0 hovers around 0V.

However, once the gas concentration surpasses the threshold, D0 switches to a low level, activating the digital indicator light. Additionally, the output voltage of the analog interface A0 escalates in tandem with the gas concentration, ranging from 0.1V to 0.3V for relatively non-polluted environments and up to 4V for higher gas concentrations. Adjusting the potentiometer clockwise widens the sensing range of gas concentration, albeit only affecting the sensitivity of the TTL output.

Moreover, the digital output D0 can directly drive a relay module to create a gas switch, or it can drive a positive buzzer module to form a gas alarm. Furthermore, connecting the analog output A0 to an AD module enables the retrieval of approximate values for ambient gas concentration through AD conversion.

2) Thermal Resistance

For semiconductor devices used across consumer and industrial electronics, the concept of thermal resistance offers a straightforward approach to selecting appropriate heat sinks. Heat transfer from the semiconductor die to ambient air is visualized as a sequence of resistances: from the die to the device case, from the case to the heat sink, and from the heat sink to the surrounding air.

The cumulative effect of these resistances yields the total thermal resistance from the die to the ambient air. Thermal resistance, akin to electrical resistance, quantifies the temperature increase per unit of power and is denoted in degrees Celsius per watt (°C/W). Once the device dissipation in watts is established, and the overall thermal resistance is determined, it becomes feasible to compute the temperature rise of the die relative to the ambient air. While the notion of thermal resistance for a semiconductor heat sink serves as a useful approximation, it overlooks factors such as non-uniform heat distribution across the device or heat sink.

Additionally, it assumes thermal equilibrium within the system and does not account for temporal changes in temperature. Moreover, it fails to acknowledge the non-linear relationship between radiation/convection and temperature rise. Nonetheless, manufacturers provide typical thermal resistance values for both heat sinks and semiconductor devices, streamlining the selection of commercially available heat sinks.

3) DHT11 Temperature sensor
