Product Details

1 Overview

DAQ-GP-IRUSB USB-to-far-infrared probe is a general-purpose infrared meter reading optical probe for electricity and gas meters, launched by Shanghai DAQ IoT Technology Co., Ltd., based on infrared communication, USB transmission and wide DC voltage power supply. It can collect electrical parameter data such as energy, voltage, current and power factor from State Grid electricity meters.

Brief introduction to the infrared meter reading principle: the infrared optical probe periodically reads the parameter information of the smart meter through the infrared optical port and uploads it.

This product supports meter reading scenarios for various meters with infrared communication interfaces, such as electricity meters, gas meters and flow meters. It is suitable for electricity meter data acquisition, smart city data acquisition, power monitoring data acquisition, energy-saving and emission-reduction data monitoring systems, energy consumption monitoring systems, PV systems, intelligent monitoring, robots, smart security systems and cloud platform systems; and for electricity meter calibration and testing benches. It is especially suitable for meter reading when the main meter of a State Grid electricity meter is in a completely sealed state with no seal allowed to be opened.
