[email protected], January 2021 Here, we propose an open-source, portable, autonomous, cheap and easy-to-use device to monitor and record the concentration of CO2 in ambiant air in real-time. Using CO2 as a proxy for respiratory aerosols, the device can help define best practices regarding the ventilation of closed space (an important anti-Covid19 measure). Starting from early

It sounds very difficult for it: monitoring the water, automatic water changing, automatic feeding and so on. these are the functions that the smart aquarium required. Now I plan to do the first step–monitoring the water quality. The water contains a

VO2Max is an interesting concept that proposes that there is a natural limited ability to extract Oxygen nutrient out of the air and consume it. It is like the IQ of sports activities–some algorithm that tells you how gifted you are in doing a variety of athletic contests. It was worked on at the beginning

The objective of this project is to measure air quality by measuring the quantity of fine particles. Thanks to its portability, it will be possible to carry out measurements at home or on the move. Air quality and fine particles: Particulate matter (PM) is generally defined as fine solid particles carried by the air (source:

This might seem totally useless, considering how advance current technology can be and you might even be like “Tsk! a Thermometer?” But there is a lot of experiment based on temperature (water temperature, room temperature, etc) so digital thermometer becomes a key instrument for temperature measurement considering the other alternatives and cost/performance ratio. It is
