— The paper was a development of a detector that can sense the presence of formaldehyde in air measured in parts per million (ppm). The prototype used storage device (SD) technology to save real time data. The objective of the study was to design and develop a system that can detect formaldehyde concentration and indicate if the reading was below or above the permissible level for formaldehyde. The device can be used in chemical laboratories and mortuaries for air quality monitoring, to lessen the harmful effects of formaldehyde. Developmental method and prototyping technique were used in the study to come up with a working product of the detector. The microcontroller unit was programmed using C programming language. Tests were conducted using 5ml of formaldehyde placed in 5 liters container to determine the accuracy of the system. The device had obtained an average accuracy of 98.33% for the three trials.
