1-Channel On-Board 95% Accuracy 20-Amp AC Current Monitor with IoT Interface

Current Monitoring of AC power is now easier than ever when using the NCD series IoT Interface Current Monitoring controllers.  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 NCD 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 NCD 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 NCD 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 20-Amp current monitoring channel, precision tuned to monitor the current flow through the on-board current sensor with a 5% maximum error rate.  While each sensor is rated for 20 Amps, this controller is available pre-tuned with 5, 10, 15, or 20 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 10 AWG in size, through the center of the sensor. The on-board custom designed CPU will do the rest using I2C communications to your IoT communication module of choice. 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.

What is the NCD IoT Interface?

The NCD IoT Interface provides users with a means of changing or upgrading the IoT communications technology as new technologies emerge.  The NCD IoT Interface is directly compatible with Particle Photon for WiFi communications, Electron for Cellular Communications, Bluz for Bluetooth.  Optionally, adapters may be installed to provide a direct interface to Arduino Nano, Micro, USB, PyCom WyPy, Onion Omega, Raspberry Pi, and much more.  The NCD IoT interface allows you to re-use your hardware so it never becomes obsolete!  Based on I2C communications, the NCD IoT Interface uses only 2 GPIO lines of your microcontroller, freeing the rest of your CPU for other tasks.

Unlimited I2C Expansion

Based on our plug-and-play I2C interface standard, all NCD IoT devices are equipped with a I2C expansion port, making it easy to expand to a wide variety of sensors, current monitors, relay controllers, PWM controllers, and much more!  We are always designing new expansions for our plug-and-play I2C framework.  We are dedicated to building a product line of interconnected devices to simplify all forms of automation.  Re-use or upgrade your hardware in seconds by selecting the modules that best fit your needs, and chaining them together using the included I2C expansion cables!
