About IoT Solutions

IoT modules like WiFi modules, BLE modules, 3G/4G modules connects to your host CPU over SPI/SDIO/UART/USB interface and helps you create IoT applications using sensors and connectivity technologies. Our associated mature software portfolio stack and reference designs across multiple platforms make it easy to develop cloud-connected industrial IoT applications in few hours, making utility, logistics, security, industrial automation, home automation and so on. Just need an idea, and you can create it very quickly with minimal investment using our portfolio of products, experience, and skills.

In the Internet of Things (IoT) world, data needs to be reliably collected from millions of things, quickly transformed into actionable intelligent information. The sensor cloud platform provides required AI and Machine Learning capabilities to automate decision-making and secure management of resources in the day to day life for consumers and industrial Iot companies. Platform using state-of-the-art technologies scales well as your requirements grow. SensoCloud architecture makes it highly configurable for specific vertical application needs. Applications include logistics, security, factory automation, utility monitoring billing and control, and custom portals with mobile access and modular UI.

IoT devices usually require sensors for converting real-world data to a measured value, a processing unit, and a communication interface. Our years of global experience and knowledge pool of embedded wireless concepts, systems, services, and components enable us to innovate, design, integrate, and develop applications and products with less turnaround time.

We work with chip vendors, OEMs/ODMs, wifi modules, sensor and equipment manufacturers, operators to develop and deploy solutions best suited to meet your M2M and industrial IoT objectives with a value proposition of faster time to market and minimized the cost of development. Our knowledge pool of various testing tools, methodologies and technologies enable us to innovate, develop and execute dynamic and static scenarios, evaluating the product from top to bottom enhancing end user experience.

Time is money, Whiznets offer developer friendly packages to include WiFi modules in your low footprint micro-controller based products. Package enables you to build complete WiFi application project in the shortest time spending minimal engineering effort. Options of OSless/RTOS and Linux/Android allows you to use our wifi modules in multiple levels of applications. Linux/Android option is available for SDIO interface. Contact us for further information on Linux platform options.
SDK allows you to write your application together with the network stack and WLAN driver to run everything on one micro-controller, saving you cost and power.

Starter kits are available for many processor technologies based on Cortex-M3, Cortex-M4, Cortex-M0+, AVR32, PIC32, ARM7, ARM9 CPUs with SPI and SDIO interfaces. Each starter kit comes with IoT wifi modules and WiFi software SDK required for your applications development. A sample project with reference network stack (LwIP) integrated with WiFi driver stack along with a sample application allows you to use reference network stack or integrate your own network stack to WiFi driver stack library.
Starter kits allow you to kick-start your projects very fast with a ready out of the box environment. You directly start writing a prototype of your application or you take the infrastructure and port it on your own processor platform.
The package of these starter kits is portable to other platforms, you can choose the one that is closest to your CPU, tool chain and interface. If you do not see your configuration, contact us, and we can provide you the specific information for your configuration.
For Linux/Android SDK requirements on SDIO interface, we work together with you to provide a ported SDK for your platform-specific needs. Contact us for discussion on your requirements and a custom quote.

Take advantage of our growing versatile solutions portfolio and expertise to reduce your cost, optimize your operations and improve your time-to-market. Contact us for further discussion on next innovative idea in your mind to change the world and let’s see how we can work together to make them a reality.
