Hard hats are a ubiquitous piece of safety equipment on every major job site. The first step in Wearable Technology for construction, therefore, should consider the hard hat as a "Smart" improvement. Our project explored this potential by applying inexpensive, off-the-shelf hardware to hard hats to create a development environment for Wearable Technology in Construction.
In this particular example of Wearable Technology, we're applying temperature and humidity sensors, along with video capture, to hard hats. Construction is a huge industry ($776 billion in 2011 with 9.1 million workers). That which is measured, improves. By measuring these factors and stresses, we can improve awareness and productivity of workers.
How are we hacking our hard hats?
We are using the following hardware to hack our hard hats:
- Standard Hard Hat
- Raspberry Pi - Model B
- Raspberry Pi-specific 5 Megapixel Camera
- DHT22 Humidity and Temperature Sensor
- Wifi USB Dongle
- Off-the-shelf External USB Battery
What runs this stuff?
We are using the following software to run these hard hats:
- Rasbian, a Linux flavor for Raspberry Pi
- Python, a programming language
- JPGraph, a PHP graphing program
- Joomla, website content management
