The Internet of Things (IoT) is now part of the smarter grid through the adoption of IPv6 communications networks. These 6LoWPAN-based networks address key concerns such as standards-based interoperability, reliability, low power, and long-distance connectivity.
IPv6-based communications are becoming the standard choice in industrial markets such as smart meters and grid automation. The universal data concentrator design provides a complete IPv6-based network solution integrated with Ethernet backbone communication, 6LoWPAN mesh networking and more. The 6LoWPAN mesh networking, which adopts an identical layering architecture to the WI-SUN FAN, addresses key concerns such as standards-based interoperability, reliability, security and long-distance connectivity.
Ultrasonic sensing techniques have been popular in smart water meters because the technology avoids any moving parts which are prone to degrade over the lifetime of the product. The MSP430FR6047 microcontroller (MCU) family takes ultrasonic sensing solutions to next level of performance delivering <25ps of accuracy, detection of low flow rates <1 liter/hour and high precision of <5ps.
This section covers system-level examples for wireless networks on smart grid IoT. We will provide software- and system-level details for two system examples: 6LoWPAN-Contiki and sub-1GHz sensor to cloud industrial IoT gateway reference design.
This section summarizes the wireless network challenges and solutions for a smarter grid IoT training series.

Hundreds of millions mechanical water meters are deployed around the world today. Market pressure pushes water utilities to add intelligence and allow for automated readout and billing on top of water waste control. RF-enabled electronic flow measurement modules provide a cost-effective solution without full meter replacement and are the main building block for fully electronic smart water meters with impeller principle.
Fourth part of the session explains representation of Voltage or Current waveforms in Time and frequency domain and also looks at the customer use case for application of Time or frequency domain Analysis. The session also explains different sampling approaches like Simultaneous sampling, Coherent sampling, Oversampling to improve system performance, criteria for ADC selection and choice between SAR and Delta-Sigma ADCs. There is a list of TI products that can be considered during the design of the AIM and finally provides overview for Focus ADCs for this session.
IPv6-based communications networks are becoming the standard choice in industrial markets such as smart meters and grid automation. These 6LoWPAN-based mesh networks address key concerns such as vendor interoperability, long-distance connectivity, security and reliability. This training will cover system- and software-level deep-dives on new RF 6LoWPAN mesh solutions, which implement open-source based 6LoWPAN mesh stacks on top of the frequency hopping based TI-15.4 stack.
PT100/500/1000 Resistance Temperature Detectors (RTDs) are widely used in grid infrastructure and factory automation applications where high precision temperature measurement is often required. Technical requirements include either 20 mK precise Differential Temperature Measurement (DTM) for heat and cold meters from 0 to 180°C or better than 400 mK precision over the full range of -200 to 850°C for industrial sensor transmitters.
Shunt sensors are rapidly replacing current transformers as the preferred current sensing solution for electricity meters(e-meters) around the world.
