This 3-Channel high-accuracy current monitoring controller makes it easy to get AC current measurements into your favorite IoT cloud platform. This current monitoring controller is available pre-tuned in your choice of 10, 20, 30, 50, 70, and 100-Amp ranges.
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 handles all of the current calculations for energy monitoring applications. Use our Particle library to communicate energy monitoring data to the Particle cloud or adapt our library for your specific application using the Arduino wire language.
This device provides an ideal energy monitoring solution for most industrial and commercial applications at a low cost with unmatched accuracy.
This controller includes 3 off-board current sensors and an I2C cable.
To use this device, simply run an AC power wire through the opening of the current sensor. This controller will read the magnetic field inducted onto the current sensor and provide you with a real-world current measurement value that is 98% accurate (prior to calibration).
This current monitoring controller includes our second generation firmware, which maintains best possible accuracy when measuring inductive loads, minimizing the need for calibration. This controller is pre-calibrated for resistive loads, but has demonstrated 98% accuracy when measuring most inductive load sources.
This controller includes split-core sensors with 1.5 Meter wires (around 5 feet). Split-core sensors can be opened and clamped around existing wire, greatly simplifying installation.
This controller includes an I2C expansion port and I2C cable so you can easily expand into other current monitoring controllers, sensors of all types, relay controllers, FET drivers, and much more.
Key Fob Compatibility:
This controller is capable of hosting the PKFR Key Fob receiver for applications that may require a hand-held wireless remote control.
For AC Current Measurement Only. This controller is tuned specifically for the included sensors, and may not be used with any other sensor. The sensor rating of this controller is 100 Amps; however, this controller is tuned according to your order. It is not possible to measure current outside the tuned range of this controller. Never exceed 110% of the rated current range of this controller (10, 20, 30, 50, 70, or 100-Amp depending on variation) or permanent damage to the controller may result. To achieve highest possible accuracy, each channel may require calibration for the type of load under measurement. As with all current sensors of this type, loads below 1 Amp (1% of the sensor rating) are known for significantly decreased accuracy (around 90% or less). To increase accuracy of low-current loads, consider doubling the readings by looping your AC load wire through the sensor a second time. This will effectively double all readings and provide greater low-end accuracy.
Excessively noisy loads may greatly affect accuracy, but our testing has shown 98% or better accuracy with most loads tested. This controller dedicates 1.3 seconds for measurement of each channel and cycles through all available channels continuously. We recommend querying this controller every 10 seconds for best results.
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.
