Oak trees keep absorbing carbon dioxide long after their annual growth has ended, revealing that photosynthesis and wood ...

For many people, photosynthesis is a dusty middle- or high-school memory. But in Northwestern Engineering’s new Data-Driven Plant Science course, photosynthesis is a live signal to measure, analyze, ...

This research is aimed to explore the efficacy and comparison of low-cost light sensor measurements for agricultural applications. For this reason, TSL2561, BH1750, and TEMT6000, low-cost light ...

Methods and explanation can be found in /src/MH-Z14A.h In case of communication issues with the sensor, please first check for sufficient power supply (the sensor needs at least 150 mA peek). MH-Z14A ...

ABSTRACT: Environmental monitoring is today a key challenge for public health, urban planning, and scientific research. Official monitoring stations, although highly accurate, remain expensive and ...

An excellent low-cost CO2 monitor (under $40) is the INKBIRD PTH-10C (see review here). My wife has also made a cheap homebuilt CO2 sensor for about $30 using Arduino technology (see instructions here ...

Abstract: This paper presents the development of a cost-effective, solar-powered, real-time air quality monitoring and hazard alert system utilizing an Arduino microcontroller integrated with gas and ...

Indoor air quality measurements using a portable home sensor of good air quality (CO2 of 552 ppm) at a supermarket (left); not-so-great air quality (CO2 of 936 ppm) at a coffee break during the 2023 ...

Humans spend about 80 per cent of our time indoors, but keeping track of the air we breathe usually requires expensive lab-grade equipment. Researchers at Concordia and Qatar University have created a ...

Atmospheric CO 2 levels have increased as a result of anthropogenic activities. This rise has contributed to global warming, ocean acidification, and the degradation of ecosystems. Addressing this ...

What if you could take control of the air you breathe indoors, making sure a healthier and more comfortable environment for you and your loved ones? With indoor air quality directly impacting ...
