  • Passive IoT environmental protection metering is a self-receiving working power supply (no need to use switching power supply), wireless transmission real-time power detection unit, detection range: current: 0-1000A; voltage 0-1000V. Monitorable: voltage, Current, frequency, active power, reactive power, power factor, harmonic analysis and accumulated power.

    It's with Internet of Things NB-IOT, LORA, 433MHz and other wireless transmission, RS485, CAN and other wired transmission.

    This product is mainly used for environmental protection condition monitoring, from environmental protection equipment monitoring to enterprise production status monitoring, collecting pollution equipment emission data and pollution control equipment data, controlling the rational use of enterprise equipment, is an important means to consolidate the existing pollution source automatic monitoring construction results. . And by collecting the total electricity consumption of the enterprise and the electricity consumption data of the production equipment and environmental protection equipment, the data analysis shows that the production conditions are abnormal.
