𝗣𝗜𝗗 𝗯𝗮𝘀𝗲𝗱 𝘁𝗲𝗺𝗽𝗲𝗿𝗮𝘁𝘂𝗿𝗲 𝗰𝗼𝗻𝘁𝗿𝗼𝗹 𝘀𝘆𝘀𝘁𝗲𝗺 𝗳𝗼𝗿 𝗺𝗲𝗱𝗶𝗰𝗮𝗹 𝘀𝘁𝗼𝗿𝗮𝗴𝗲 𝘂𝗻𝗶𝘁

Temperature-sensitive medical supplies, like vaccines, demand precise control to maintain their efficacy. To address this, I recently worked on a 𝗣𝗜𝗗-𝗯𝗮𝘀𝗲𝗱 𝘁𝗲𝗺𝗽𝗲𝗿𝗮𝘁𝘂𝗿𝗲 𝗰𝗼𝗻𝘁𝗿𝗼𝗹 𝘀𝘆𝘀𝘁𝗲𝗺 designed for medical storage units, ensuring reliability and adaptability for 𝙘𝙤𝙡𝙙 𝙘𝙝𝙖𝙞𝙣 𝙢𝙖𝙣𝙖𝙜𝙚𝙢𝙚𝙣𝙩.
This system is designed to work within the range of 4°C to 25°C

The system leverages a 𝗗𝗦𝟭𝟴𝗕𝟮𝟬 𝘁𝗲𝗺𝗽𝗲𝗿𝗮𝘁𝘂𝗿𝗲 𝘀𝗲𝗻𝘀𝗼𝗿 for accurate monitoring and a 𝘁𝗵𝗲𝗿𝗺𝗼𝗲𝗹𝗲𝗰𝘁𝗿𝗶𝗰 𝗺𝗼𝗱𝘂𝗹𝗲 (𝗧𝗘𝗖) 𝗳𝗼𝗿 𝗲𝗳𝗳𝗶𝗰𝗶𝗲𝗻𝘁 𝗵𝗲𝗮𝘁𝗶𝗻𝗴 𝗮𝗻𝗱 𝗰𝗼𝗼𝗹𝗶𝗻𝗴. 𝗨𝘀𝗶𝗻𝗴 𝗮 𝗣𝗜𝗗 𝗮𝗹𝗴𝗼𝗿𝗶𝘁𝗵𝗺, the setup dynamically adjusts the TEC’s output, maintaining stable temperatures even in fluctuating environments.

A 𝘂𝘀𝗲𝗿-𝗳𝗿𝗶𝗲𝗻𝗱𝗹𝘆 𝗶𝗻𝘁𝗲𝗿𝗳𝗮𝗰𝗲 𝘄𝗶𝘁𝗵 𝗮𝗻 𝗢𝗟𝗘𝗗 𝗱𝗶𝘀𝗽𝗹𝗮𝘆 𝗮𝗻𝗱 𝗶𝗻𝘁𝗲𝗿𝗮𝗰𝘁𝗶𝘃𝗲 𝗯𝘂𝘁𝘁𝗼𝗻𝘀 𝗮𝗹𝗹𝗼𝘄𝘀 𝗿𝗲𝗮𝗹-𝘁𝗶𝗺𝗲 𝘀𝗲𝘁𝗽𝗼𝗶𝗻𝘁 𝗮𝗱𝗷𝘂𝘀𝘁𝗺𝗲𝗻𝘁𝘀, making the system adaptable to diverse operational needs.

It's thermally optimized, all mechanical heat coupling is done using thermal paste, also the system is sealed from ambient disturbance using thick leather sole, tight sealing is done with neodymium magnets.

It was fun working with thermoelectric peltier module.
I am looking forward to applying it in a more robust real world application, applying the knowledge of control systems (PID control) in robotics and aerospace.
