Temperature and Humidity Monitoring

His experience includes selecting and deploying data loggers and IoT sensors for warehouses, cold-chain environments, storage areas and industrial operations. Important considerations include sensor placement, network availability, alert thresholds, data retention, reporting and operational response procedures.

Indoor Air Quality Monitoring

YK supports the selection and deployment of professional indoor air quality monitoring systems for offices, commercial buildings, schools and industrial workplaces. Depending on the application, monitored parameters may include carbon dioxide, PM2.5, PM10, total volatile organic compounds, temperature, relative humidity, ozone and other environmental indicators.

Heat-Stress and WBGT Measurement

His work includes measurement solutions for workplace heat stress using Wet Bulb Globe Temperature instruments. He writes about the differences between WBGT, heat index and ordinary air-temperature readings, with emphasis on using suitable instruments and referring to applicable Singapore workplace guidance.

YK Yeo actively participates in discussions about the future of environmental monitoring in Singapore.
