Current Monitoring of AC power is now easier than ever when using the NCD series IoT Interface Current Monitoring controllers. Our customized dedicated onboard 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 favourite 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 the I2C expansion port, making it easy to expand to a wide variety of sensors, relay controllers, PWM controllers, and much more!
This controller has eight 70-Amp current monitoring channels, precision tuned to monitor the current flow through the onboard 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 centre of the sensors. The onboard custom designed CPU will do the rest using I2C communications to your favourite 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 onboard 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 DCube 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 centre positive barrel connector or onboard terminal block for directly wired power supplies.
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.
