Abstract: Healthcare workers in contact with formaldehyde in histopathology laboratories are at greater risk than other individuals. Formaldehyde gas is relatively difficult to detect by the human senses. Healthcare workers in contact with formaldehyde in histopathology and anatomy laboratories are at greater risk than other individuals because they are exposed to higher amounts of formaldehyde on a daily basis, either through inhalation or direct contact with the skin. It is difficult to make measurements of safe levels of formaldehyde gas. Exposure to very high levels of formaldehyde over many years has been linked to rare nose and throat cancers in workers. This project is proposed to design and develop a formaldehyde leakage detector for monitoring and to analyses formaldehyde reading for safety precaution. The component that use is exhaust fan and MQ- 135 as an input, Arduino Uno is the processor that control the input and output, and for the output are buzzer, red alarm light and LCD display. As a result, exhaust fan will absorb air in surrounding into the box device, then the buzzer and redlight alarm will trig to give alert to the people in the laboratory if leakage occur to 10ppm concentration in air, when accurately measuring, the proper alarm point for the gas detector and the LCD display will display the information of the leakage if leakage occur. This project will come out successful by detecting the gas leakage. Therefore, it may help the laboratory worker to aware about formaldehyde leakage and help to track the position of leakage and smoothing out their daily work
