A complete "End-to-End" IoT Micro PLC Solution

A complete End-to-End IoT PLC Solution

The EQSP32 is an end-to-end IoT platform designed to bridge the gap between the physical environment and digital control systems. It enables real-time monitoring and automation by seamlessly connecting sensors, actuators, and cloud-based applications.

Equipped with a pre-built API, the EQSP32 simplifies device integration and ensures a smooth connection to various IoT platforms.

Whether using Home Assistant, Node-RED, Dashio, Arduino Cloud, Blynk IoT or a custom solution, EQSP32 provides a reliable and scalable foundation for smart applications.

Build Smartphone Apps that are Truly Yours

Creating a smartphone app interface tailored to your needs is as easy as things get. Our intuitive design tool streamlines the process, allowing you to drag and drop elements like buttons, sliders, and widgets. You can resize these elements, change captions, and customize text styles and colors to make the app truly reflect your personal or brand aesthetic.

What sets this app builder apart is its real-time awareness of the EQSP32’s IO states. Through the integration with a cloud-based real-time database, your app is continuously updated with the current status of the EQSP32’s inputs and outputs. This feature ensures that you have up-to-the-second information and control over your device, whether you’re adjusting tub jets or implementing other innovative ideas.

Once your app looks and functions as desired, deployment to the iPhone App Store, or Google Play, is just a click away. Your custom app, complete with real-time device monitoring capabilities, will be ready on your device. This makes the EQSP32 an ideal solution for both ambitious commercial projects and personal ventures, allowing for smart, connected, and responsive app creation.

A Safe, Professional-Grade Solution

While single board computers and relay shields are common, creating a control system for high voltage lights and pumps that gains utility company approval is challenging. The EQSP32, with its DIN-mount enclosure and 24V operation, avoids restrictions in electrical installations, ensuring safety and compliance. High voltage switching can be achieved using any of the numerous certified relays available at electrical stores, further enhancing its versatility and professional-grade reliability.

All in a Compact enclosure that snap onto any standard DIN rail

The EQSP32 is designed to snap neatly into inexpensive electrical cabinets and distribution boxes, next to power supplies, relays and other components that may be required by your application. Want our EQSP32 outdoors? you’ll find plenty of waterproof DIN boxes an any electric supply store.

Hear it From Our Users

"This must be the only such controller where a terminal can be used to drive a 1A load or read a low-level analog signal with full protection. We do a lot of different systems, so having 16 configurable IO terminals sure beats having 8+8 (or any other fixed combination) of single type ports."

"We were quite skeptical about the no-code promise but it really works. We were able to build our application with just a few prompts and minor tweaking of the source code. Impressive time saver."

"The Erqos folks know their stuff. We had a communication issue between the EQSP32 and a noisy motor controller. The kind of problems that vendors would normally point to faults on the other guy's product. They helped pinpoint the root cause and gave us a working solution. Thanks guys."

"Allowing easy WiFi SSID and Password setup and change has always been more work than I cared for. Erqos' library and smartphone app makes it a zero-effort thing. Great job, team!"

"Like being able to connect the PC via USB, using a standard cable and without taking the electrical cabinet cover off. Hard to believe that nobody thought of that before on a DIN-mount Micro-PLC."
