Week Four This Week's Overview: We constructed the "window's" mechanism with our stepping motor and 3D printed gears and actuator. We also created a structure to help demonstrate how our system operates. It is composed of 2 parts: an enclosed box housing our circuit (to indicate that our system is embedded inside the car) and an acrylic box that acts as a gas chamber to help us test our system in a closed environment. Main Tasks: 1) We changed our air quality sensor to another calibrated sensor:  Figure 1: MQ-135 Gas Sensor [1]. This MQ-135 measures the CO2 and other organic compounds that are found in the air. As opposed our old MQ-135 sensor, we were able to measure sensible values because it was pre-calibrated.  We used this equation in the code: CO2 (ppm) = A x (R_s / R_0)^(-B) R_s = ((V_in - V_out) / V_out) / RL where  R_s:  sensor resistance at a certain gas level             R_0:  sensor resistance in clean air ...

  Week One Project Overview: This projects aims to create an adequate gas safety system for vehicles. It is an embedded system that checks for high levels of Carbon Monoxide (CO) gas and opens the vehicle's windows slightly (approximately 2cm) until the air is safe to breathe again. Moreover, it switches off the AC to allow quicker gas exchange. It also sounds an alarm and displays a warning message to alert the passenger/s of the high levels of CO. However, since this is a prototype and simulating the system with actual CO would be extremely dangerous, the system checks for high levels of CO2 and performs the same operations. Furthermore, the system also senses and displays the overall quality on a screen. This Week's Overview: We mainly focused on testing all of our components to make sure they were all working up to an acceptable standard. Main Tasks: 1) The Raspberry Pi Pico W did not have any headers/pins soldered to it; therefore, we soldered wires onto the 3.3V and GND p...
