In just 6 short minutes, you can learn how to monitor the potential injuries of construction workers on a job site. Learn how to quickly get data from a TI SimpleLink SensorTag into the IBM Watson IoT Platform.

In this video:

In this video, Chris Anderson demonstrates a simple Internet of Things scenario that monitors the potential injuries of construction workers on a job site. He shows you how to quickly get data from a TI SimpleLink Bluetooth low energy SensorTag into the IBM Watson IoT Platform.

For this demonstration, Chris attached a TI SimpleLink SensorTag to a hard hat, which he configured to send acceleration and orientation data by way of an iPhone app to the Watson IoT Platform. Once the data is received, he used a Node-RED app (with custom TI nodes available) to analyze and react to the data. The analytics is used to determine if a construction worker has fallen or has been hit by equipment while on the job, and then if a threshold is met, additional data is pulled from a Cloudant database to send an alert using Twilio to send an SMS alert to the worker’s supervisor.

You connect the TI SensorTag to the TI iPhone app, and you then push the data collected from the sensor to the IBM Watson IoT Platform in the cloud. Chris then steps through the nodes in the Node-RED app. The Node-RED flow is available in his GitHub repo: connected-hardhat.

Around the 4:18 mark of the video, Chris simulates a fall by dropping the hardhat and simulates an impact by hitting the hardhat with an engineering hammer. In each instance, he shows the alerts being sent to his cell phone by way of Twilio. He reiterates how important it is to set the right thresholds for the sensor data to be able to identify potential safety issues like falls and impacts on a construction site.
