The remote-controlled cold room I'm working on will provide a controlled environment for keeping perishable food items, like fruits and vegetables, at a temperature between 25 and 5 degrees Celsius. At temperatures ranging from 5 to –20 degrees Celsius, it also offers storage for meats and vaccines. By allowing for exact temperature control, this system creates the ideal environment for maintaining the quality and security of the stored goods.
many researchers and manufacteres have done the same concept of using the peltier to provide the coldness in specif room regarding to the degree of coldness required. through that allow me to presante this coleague called "Silvio Pietro Monticelli"who done "Gene Freezz which is the prototype of a portable cooler, with an embedded freezer, to support DANA barcoding activities in the field." here you can find more detail on the project even if he did'nt controlled the cold room remotely.click here:References
the design of my project will concerns with mechanical structure design and eletronic circuit design and cooling system design

my system is contains two parts
MECHANICAL PART,
ELETRONIC PART
AS we are doing digital fabrication and how to make any thing almost , i started with cad which is computer ided design of my structure and then genarate g-code of my design in CAM process which is computer aide manufucturing .
eletronic part of my project also concerns with CAD and CAM the same with mechanical but the soft ware used and machine used for manufacturing are difference.there for pcb design was designed in kicard and printed with roland machine.
the quastion to be answered are how can we controll the cold rooms remotetly to reduce the post haverst loss?
and What role does effective crop preservation play in reducing post-harvest losses and conserving perishable food in remote-controlled cool rooms?
both quastion will be answered by this paragraph of
In order to reduce
post-harvest losses and preserve perishable food in remotely controlled cool rooms,
effective crop preservation is essential. It is simpler to guarantee ideal storage conditions
for crops by putting advanced monitoring and control systems in place, like the culminating project in the Fab Academy program here in Rwanda. Real-time temperature and humidity monitoring made possible by this technology enables prompt adjustments to maintain perfect conditions. Perishable food's shelf life can be increased by lowering temperature variations and environmental control, which also lowers spoilage and
post-harvest losses and ultimately promotes sustainability and food security.
one of global challenge to be answered.
my project will reflect on fab academy courses such us
Regarding to the course and to pic covered in fab academy program my project scope are
honestly i will deliver the following thangible and intergible asset created and procured by me for the sucess of the project
