By means of wireless communication and powering from the measured voltage cable, it can greatly reduce the cost and time of deployment, and satisfy the demand of distributed deployment and quick setup. Moreover, the features of Sub-GHz radio frequency and data supplement mechanism effectively improve the reliability of the wireless communication especially in the factory environment that is seriously shielded or with limited space. Considering the maintenance and installation issues, the iWSN-9603 series is configured by the DIP switches, and uses special housing with IP33 protection to avoid the circuit short while the fire sprinkler system is activated when the module is placed outside the panel box. Through the design of RTC and data timestamp, the iWSN-9603 series can fit in the power saving applications, such as machine and process power efficiency improvement, power information administration, calculation of carbon emission, predictive maintenance, and big data analysis of power consumption.
