Current Monitoring of AC power is now easier than ever when using the DCube Store series 70-Amp AC Current Monitor with IoT Interface.  Our customized dedicated on-board CPU handles all the current monitoring functions for you, all you have to do is ask the controller for the amperage reading.  Using our IoT interface, plug-in your favorite IoT communication module and develop firmware to read energy anywhere in the world!  The DCube Store IoT interface support Particle Electron for cellular current monitoring.  Use the Particle Photon to monitor current over WiFi.  The IoT interface also supports Bluz (Bluetooth BLE) or you can use one of our adapters to plug in Arduino Nano, Arduino Micro, USB, PyCom WyPy, directly on-board!  Plug in the SI I2C adapter for interface to Raspberry Pi, BeagleBone, or Arduino Uno.  The DCube Store IoT interface standard makes it easy to connect to just about any computer or microcontroller!  Based on our plug-and-play I2C interface standard, all DCube Store IoT devices support I2C communications using a I2C expansion port, making it easy to expand to a wide variety of sensors, relay controllers, PWM controllers, and much more!

This controller has one 70-Amp current monitoring channel, precision tuned to monitor the current flow through the on-board current sensor with a 3% maximum error rate (Tested up to 70 Amps).  While each sensor is rated for 70 Amps, this controller is available pre-tuned with 10, 20, 30, 50, or 70 amps.  These tuning ranges provide the best possible accuracy within the specified range, though users should take care to never exceed the pre-tuned range.  To use this device, simply run an AC power wire, up to 10mm in size, through the center of the sensor. The on-board custom designed CPU will do the rest using I2C communications to your favorite IoT communications module. This controller includes an I2C expansion port, allowing expansion for more current monitoring inputs or other types of I2C sensors and devices.  Four on-board address jumpers allow expansion of up to 16 current monitoring devices through the I2C expansion port. Mix and match current monitoring controllers of any size to meet your specific application requirements.

Software developers can take advantage of our ControlEverythingCom GitHub repository for current monitoring and programming samples.  This device only requires a 12VDC power supply for operation, which may be plugged into the controller using a 2.1mm center positive barrel connector or on-board terminal block for direct wired power supplies.

nodeLynk™ IoT Device Expansion

This is an IoT Device which accepts a common processor and provides on-board sensing or control capabilities.  This IoT device may be expanded to include additional hardware functionality using nodeLynk Expansion Devices.  The Dcube Store IoT socket found on IoT devices is capable of directly handling ESP8266 and ESP32 series processors as well as Particle Photon and Particle Electron.  We also manufacture many adapters for the Dcube Store IoT socket for Arduino Nano, Micro, and Feather microprocessor modules.  Between the socket is a nodeLynk connector, which is used for I2C Expansion.

What is nodeLynk?

Chain expansion devices using nodeLynk. Connect a wide variety of accessories to expand the capabilities of a nodeLynk compatible controller.  Use nodeLynk to add Relay Controllers, Sensors, PWM Drivers, Displays, and a wide variety of 4-20mA, 0-10V ADCs and DACs, as well as a wide array of TTL & Isolated GPIO devices.  All nodeLynk devices use I2C communications to chain devices together.  nodeLynk is an easy way to expand functionality without soldering.  nodeLynk allows expansion in seconds so you can focus on your software and firmware development.
