Hardware & Software That Works Together Seamlessly

We connect devices & the software that brings them to life


3Si2 concurrently designs and develops hardware and its corresponding software, so integration is always highly efficient.

Need to build a complete hardware interface from scratch, or develop new software for your current hardware? 3Si2 has a wide range of knowledge in engineering hardware and software for both end consumers and commercial & industrial applications. Our hardware development and software development teams work hand in hand to ensure that your hardware and software function cohesively. From the very start of the project to the last development cycle our hardware engineers are synchronizing, strategizing, and testing right along side our software developers.


Power and resource efficient architecture for both high-performance and ultra-low-power devices.

3Si2 hardware looks great, is easy to use, and consumes power and resources effectively. These three characteristics are the cornerstone of all hardware engineering work that we engage in. To achieve the ideal hardware interfaces closely knit hardware and software teams are managed through the agile methodology which provides the most creativity possible while still maintaining structure, process, order and timelines. The agile approach not only gets you a great end product, it helps keep the cost of your project manageable and predictable.


Hardware and software interfaces are more powerful when combined with technologies like Z-Wave, Bluetooth, WiFi, IR, & RFID.

Allowing your devices to communicate with other devices opens up endless possibilities that consumers and business are craving. With more and more smart devices powering people’s homes consumers are starting to expect more out of their connected devices. The hardware and software that powers modern devices needs to empower the user to connect and control all other smart devices in their world – with 3Si2 engineering this dream can become a reality.


Electronic Queuing Interface

Electronic Queuing Interface

The electronic queuing interface creates a system that minimizes both perceived and actual customer wait time, thus improving the overall customer experience while best utilizing customer service or checkout resources. Instead of having customers guess which line will be the fastest, electronic queuing allows all customers to wait in one line as they are summoned to the next empty service counter.

Use of Raspberry Pi and Z-Wave makes this interface a cost effective solution for nearly any industry. These technologies also provide great flexibility, speed, and performance.

5 components make up the electronic queuing interface:

1) the main display and processing unit (powered by Raspberry Pi)
2) the memory unit (for deploying setup information)
3) the configuration software
4) wireless remote control units (powered with Z-Wave)
5) an outlet/port for connecting external devices such as a “next customer” sign/light.
