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 six 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 I2C Interface?
The supplier of plug and play modular hardware using the I2C Interface connector standard. It allows you to chain together several devices on the I2C bus, and communicate to each device individually at high speed (subject to the limitations of I2C). The I2C Interface uses a standard 4-Pin I2C Input and I2C Output connector. These devices communicate on the power of 5V I2C data and provide 5V DC power through this connector. The advanced embedded devices use standard I2C communications for all data transport, which is supported by nearly every microcontroller in production today. The I2C Interface is strictly a 5V standard, which is ideal for transport across longer cables. The device Package always includes a 6″ (152mm) 4-conductor I2C cable. The I2C based Mini Modules always include a 3″ (76mm) 4-conductor I2C cable. Cables and connectors are available separately for designers who would like to include their own I2C Interface into their designs.
Plug and Play Connectivity
The advanced Embedded devices will plug into any available I2C Output. This includes just about everything we make in the DCube Store IoT Category, including all the other IoT devices. We also supply a wide range of I2C adapters that make it easy to plug I2C Devices directly into most computing platforms. The advanced Interface adapters are available for Arduino, Banana Pi, BeagleBone, Bluz, C.H.I.P., ESP8266, Onion Omega, Particle Photon and Electron, PyCom, Raspberry Pi, 2, 3, and Zero, and Windows. We are always working to add new platform support for I2C devices. These Interface devices are compatible with just about everything in the microcontroller industry.
Unlimited I2C Expansion
Based on our plug-and-play I2C interface standard, all the I2C devices which are equipped with the above protocol output ports, 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 modular 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 within seconds by selecting the modules that best fit your needs, and chaining them together using the included I2C expansion cables!
Powering I2C Interface Devices
Some I2C devices require an external power supply, others may be powered through the 4-Pin I2C bus connector at 5VDC, and other devices are jumper selectable between external and I2C bus power. All I2C mini-modules are powered through the 5V I2C bus connector, greatly simplifying connectivity.
