||To develop prototypes and test them in controlled and open conditions. In year one, we focus on technology development and selection. We aim to test a number of low-cost, commercially available sensor elements that are relevant to haze detection. Haze consists largely of very small particulate matters (PM). Other components of haze include carbon monoxide and nitrogen oxide. Temperature, humidity, wind and rainfall also affect the severity of haze in a specific area. We also intend to look for reliable indicators of haze as well as impacts to rural citizen's health.
