The construction industry is massive but not so advanced in adapting and utilizing technology. Sensors and sensing technology are critical elements that can enhance the digitalization of the construction industry. The need for low-cost sensors is rapidly increasing as the industry steps into the construction 4.0 phase. This research is an exploratory study on the potential of low-cost sensors, concentrating on the temperature and humidity sensors in the production stage of construction. The methodology used in the research is a qualitative approach consisting of literature review and interviews. The literature review identified the state of art of low-cost temperature and humidity sensors. From interviews, the constraints, adaptation factors were identified. The potential application of the low-cost temperature and humidity sensors were identified from the literatures and interviews. The conclusion of the research was that there is a knowledge gap in the field of low-cost temperature and humidity sensors. Furthermore, there is lack of adaptation of sensor technology in the production stage of the construction industry even though it has potential to improve the productivity and quality.
