We hired Dedicated Developers to help us build and design both hardware GPS sensors used in the transportation industry as well as the web application and mobile apps to monitor the sensors. The sensors connect the transportation sector to the Internet of Things (IoT). It was challenging to find developers that had the complete package of skills we needed for this project. Lots of companies had the software skills, but not very many had the hardware skills. We were thrilled when we found Dedicated Developers, because they were able to do both the hardware and software designing for us. The hardware they created are sensors used to monitor a wide variety of things for the transport industry. The sensors can monitor speed, acceleration, elevation, breakdown, GPS route coordinates, and then transmit all the data through the cellular network. Our clients can then see all the data points within the centralized application control panel to fully monitor their cargo. They did a lot of initial research and were able to suggest hardware components and sensors that would be the best configurations that would reduce the costs during mass production. They helped us figure out the best components that are reliable, durable and cost effective, so the total hard costs for each finished sensor goes down, and profits go up. They were able to bring the total cost of each unit down by 21%. They were creative while building the prototype sensors, which they were able to do quickly within a couple months. The software they created to run and monitor the sensors uses the latest cutting-edge technology, and connects our industry to the Internet of Things, which is fast, efficient, responsive and very well designed. The hardware sensors they created for us are top notch, and the monitoring software to run and monitor them has been very well received by our clients. It’s been able to make our company a cutting edge leader in our industry.
