Manual ways to record readings are being used which consume a lot of time and are less accurate [1]. In a recent study, it is proposed by Chen et al. that if the general labs could be equipped with microprocessors and mobile data collection tools, the trend of working in lab will be directed more toward better data analyses instead of sp
