Design SensorWireless Microcomputer /Processor/DSP Texas Instruments

Recently, solutions such as air conditioning management and preventive detection based on data acquired in factories and buildings are increasing. One of the challenges faced by providers of such solutions is the selection of the wireless standard used to transmit data.

Texas Instruments (hereafter TI) offers a product called the SimpleLink series that supports various wireless standards. In addition, this series has the feature that software can be reused, so it can be easily ported even if the installation environment changes and the wireless standard needs to be changed.

For more information on the SimpleLink series, please see this article.
What is the SimpleLink series for IoT with low power consumption?

In this article, we will use the SimpleLink series evaluation board to introduce the contents of a demonstration video that assumes an HVAC system (= heating, ventilation, and air conditioning system) used in home automation and building automation.

For the factory automation demo shown later in the video, check out this article.

Demonstration assuming an HVAC system

The left half is a demo configuration for an HVAC system. To explain the demo contents briefly, it is a demonstration that the rotation speed of the fan changes when the temperature changes.

0:41 - 2:42 Explanation of demo configuration

The upper left is the thermostat of the WiFi connection. The CC3220 LaunchPad is configured by connecting a temperature sensor and LCD Booster Pack, and it also supports a touch panel and operates as an HMI.
The middle row is the Sub 1GHz edge node. The CC1310 LaunchPad is equipped with a temperature sensor BoosterPack.
In the middle on the right is an Ethernet-based gateway. I'm using the MSP432E4 LaunchPad.
The bottom left is the air conditioning fan. A fan is connected to the CC1310 LaunchPad.

2:43 - 3:27 Demonstration of the demo

The temperature is set with the HMI on the upper left, but if you set a value lower than the current temperature, the lower FAN connected by 802.15.4 will turn and try to lower the temperature by MQTT via the gateway.
The sensor node in the middle stage uploads temperature information to the cloud via the gateway with 802.15.4.
These can be bi-directionally set and monitored from a PC terminal connected to IBM Watson IoT via a web browser.

Demo configuration

Below is the demo configuration of the home automation introduced in the video.

TI reference designs to help you find ideas

TI has reference designs that provide comprehensive design data such as schematics/block diagrams, BOM costs, design files, and test reports.

Our reference designs provide the information you need, from embedded processors to power management and even the signal chain, allowing you to quickly evaluate and customize your system, reducing product development time. abbreviate

You can also search for reference designs by application, so I think you can use it to find product ideas. Below are the demos and related reference designs that I introduced this time, so please take a look at them as well.
