This project was created by our partner Sensirion, who is a leading sensor manufacture of gas and liquid flow sensors, differential pressure, as well as environmental sensors.

 

 

Project Technology Focuses

  • PSoC 6 Arm® Cortex®-M4 and Cortex-M0+ MCU
  • CYW4343W 802.11n Wi-Fi + Dual-Mode Bluetooth Radio
  • Sensirion Particulate Matter Sensor, Humidity/Temperature Sensor, and Indoor Air Quality Sensing
  • Arm Mbed™ OS
  • Sensor Data Transmission to Cloud via Wi-Fi

 

Project Requirements 

 

Project Description

 

With rising pollution levels worldwide, as well as the rise of smart homes and smart buildings, air quality monitoring is becoming an important capability for IoT engineers to design into their devices. Both in outdoor and indoor environments, logging air quality data, locally processing this data, and providing insights by posting to a cloud platform via Wi-Fi connectivity are valuable in ensuring health and safety. Cypress’ PSoC 6 MCU and Sensirion’s air quality sensors are the ideal choices for these systems.

This project covers the entire data flow, from reading it out from the sensors through I2C, processing the data locally, data upload to a cloud service as well as an example dashboard users can set up themselves.

Case Study Description

 

Delivering Smart Connectivity to Industrial Weighing Scales

 

Business Challenge

Connected weighing scales and POS systems have been deployed in the retail environment for many years. Serial hard wire or Ethernet has commonly been the connectivity method used. In today’s highly dynamic retail space, quick configuration of the store and the various departments is required to enable rapid product/services changes. This makes wired connectivity more and more inconvenient to maintain and even potentially detrimental to business fluidity.

This case study explores a global manufacturer of industrial and commercial weighing scales that needed an industrial-grade, reliable, and secure enterprise Wi-Fi solution for building commercial weighing machines to be used in diverse retail environments. The smart, connected industrial weighing scales would be used in retail stores and would wirelessly communicate accurate weight and pricing information of items to the retailer’s point of sale systems throughout the day. This customer needed a globally certified solution that would mitigate significant product validation and re-certification risks and cost – in addition to implementing wireless connectivity and security upon which they could depend.

 

Solution

The customer’s ideal solution was the Lantronix xPico 240 Embedded IoT Gateway hosting Cypress’ CYW43907 Dual-Core Arm Cortex-R4 Dual-Band (2.4/5 GHz) 802.11n Wi-Fi MCU. This module provides world-class dual-band Wi-Fi, antenna diversity, Enterprise Wi-Fi security and industrial-grade wireless connectivity management enabling rapid time to market.

The winning features of the xPico 240 include:

  • Hosting the Cypress CYW43907, providing world-class wireless performance in challenging RF environments through an integrated Arm® Cortex®-R4 with 2MB of RAM combined with a high performance Dual-Band (2.4/5 GHz) 802.11n Wi-Fi radio
  • Being in the Lantronix xPico module series: Comes pre-loaded with firmware that includes secure wireless network connectivity options such as the complete set of EAP authentication protocols.  There is an SDK available if unique features or customizations are also required
  • Delivering a compact footprint with full certifications making integration into the product design easy and fast

 

With these features, the smart weighing scales customer was able to build a market-ready prototype quicker, reduce total cost of development, go to production faster, and deliver a comprehensive solution to market on time.
