Abstract

The CCS811 sensor is a metal oxide semiconductor (MOX)-based gas sensor that is widely used in wearable systems to monitor air quality personally, especially in detecting volatile organic compounds (VOCs) contained in cigarette smoke. This study aims to conduct a systematic review of various studies that implement the CCS811 sensor in wearable devices for cigarette smoke detection, focusing on aspects of accuracy, sensitivity, detection time, and the effect of room size. The method used is a systematic literature review of 19 scientific articles published in the last ten years. The results of the review show that the CCS811 has several advantages, such as low power consumption, compact sensor size, real-time VOC detection capability, and easy integration with the Internet of Things (IoT) system. Quantitatively, this sensor is able to detect TVOC concentrations in the range of 20–1158 ppb, with a response time of less than 20 seconds in a small space. However, limitations are still found in terms of selectivity to certain types of compounds and the lack of studies evaluating the effect of room characteristics on detection performance. This study recommends further testing in various real-world conditions as well as the application of machine learning algorithms to improve the accuracy and adaptability of the CCS811-based wearable system in effectively detecting cigarette smoke.

Abstract

This study characterizes and evaluates the performance of an ODM Type K thermocouple in measuring temperature within the range of 0°C to 100°C under controlled laboratory conditions. The experiment utilized a hot plate as the heat source, with melting ice and boiling water as reference points for 0°C and 100°C, respectively. The thermoelectric voltage generated by the thermocouple was measured using a digital multimeter and compared with readings from an ASTM mercury-in-glass thermometer as a reference. The results showed a strong linear relationship between thermoelectric voltage and temperature, consistent with the Seebeck effect. The average deviation between the thermocouple and the reference thermometer was approximately ±0.3°C, with maximum errors within ±1°C. These findings indicate that the ODM Type K thermocouple demonstrates high accuracy, good linearity, and stability, making it suitable for laboratory and industrial temperature measurement applications.
