The IoT Current and Voltage Sensor consists of four sensors: (i) contactless Hall or CT current sensor, (ii) shunt resistor based current sensor (iii) battery voltage sensor, and (iv) temperature sensor. The four sensor signals are read by analog-to-digital converters (ADCs), processed by a programmable state-of-the-art microcontroller, and uploaded to the cloud via WiFi interface. The connectivity of the module is extensible to CAN, LoRa, GSM, Zigbee, Bluetooth, and Ethernet interfaces.
A particular feature of the product is its easy and safe installation without interrupting the primary current wire by using contactless galvanically isolated Hall sensor technology. This additionally allows the module to be used for hassle-free retrofit application.
The device is supplied directly with 5V…60V DC from the primary battery and optionally can be operated with a secondary 9V battery for autonomous use.
