We recently had a requirement to visualise data posted to AWS. We decided the easiest and most effective way to do this was by using one of AWS visualisation tools — QuickSight. After embarking on a journey of discovery (and a bit of hair-pulling to figure out how best to implement the task), we settled […]

Background  Low Power Wide Area Networks (LPWAN) are a category of RF communication systems which  trade speed for low power consumption and increased transmission distance. Lower power consumption is ideal for battery powered devices if they have very low data bandwidth requirements. Examples include smart water meters, data loggers, lighting control, agriculture sensors and actuators

Some time ago we posted an article in LinkedIn about the technology behind ultrasonic sensors which was quite tech heavy. This time however, we want to focus more on the wide variety of ultrasonic sensing applications. Before we discuss this, let’s recap with a brief technical background. Ultrasonic waves are essentially high frequency sound waves

Developing a new product can be a risky and expensive process. One way to mitigate the risk, is to include a Proof Of Concept (PoC) as part of the development program. A PoC is hardware developed to technically validate an idea or concept. It allows the business to gauge if the product will be technically

Home automation has long been a mishmash of standards and varying protocols. Along with that came confusion. There’s Z-Wave, ZigBee, C10 and many other often proprietary “standards”. Consequently, the adoption of home automation tech by many homeowners was either too expensive, too difficult, or too confusing, and that’s not a scenario which encourages adoption. Thankfully

We see IoT applied to many and varied application areas which were previously unthought of. One application is monitoring rainwater harvesting systems to measure their operation and performance. We recently undertook a project to implement this solution for a corporate client and the results were amazing. The brief was multi-facetted, including remotely monitoring the tank’s health

Many years ago I was an FAE for a prominent semiconductor vendor and had the opportunity to understand the design-in process from the vendor’s side. Suffice to say, it’s not easy competing for design-ins when the market is saturated with similar products at various price points. So you may ask, how can a vendor or

Welcome to the 3rd and final instalment of our Indoor Air Quality Monitoring (iAQM) discussion. Today we discuss a particular indoor air quality sensor we developed for a client – Grosvenor Engineering – who are leaders in analytics used in the maintenance of mechanical and HVAC equipment. iAQM Sensor We were engaged by Grosvenor Engineering

Welcome to the 2nd instalment of our Indoor Air Quality Monitoring (iAQM) discussion. Today we discuss the technology behind an iAQM sensing system. In the 3rd and final instalment, we’ll do a review on an indoor air quality sensor we developed for a client – Grosvenor Engineering. Sensors The technology used to sense iAQM parameters

In this 3 part series we discuss indoor air quality monitoring (iAQM) and it’s applicability to commercial buildings. Part 1 discusses iAQM from a building occupant perspective – the basics. Part 2 will discuss the technology behind an iAQM system from a holistic and generic perspective. Part 3 will review a commercial indoor air quality
