Design and Development of a Low-cost Sensor IoT Computing Device for Greenhouse Gas Momitor from Selected Industry Locations

The objective of the study is to develop low-cost IoT based sensor monitor real-time greenhouse gases (GHG) emissions data from selected industry locations (city blocks) in a top-down approach. Three (3) were within Suame Industrial complex (the largest single cluster artisanal engineering and light manufacturing Sub Saharan Africa even Africa) which has no reported GHG data. A was developed using Atmega328 microcontroller sim800I GSM module used collect 24-hour minute-by-minute locations. MQ-4 (methane/natural gas sensor), MQ-135 (Nitrous Oxide sensors) DHT22 (temperature humidity sensor) design. concern carbon dioxide, methane nitrous oxide. total 3627 collected analyzed three Location 3 had highest average dioxide 508.11 ppm, followed by location 2 with 477.31 ppm least 1 472.51 are above global 414.7 ppm. emission 0.1599 (1599 ppb), 0.1366 (1366 ppb) 0.1358 (1358 slightly below 1895.7 ppb. oxide zero throughout deployment at various indicated oxides sample site negligible or detectable range sensor.
