Series of Innovators: SPEC Sensors

Sotirios Papathanasiou1 Comment

Introduction

SPEC Sensors was founded in 2012 in the USA (California) by Dr. Joseph Stetter and Ed Stetter. Their gas sensors, analog and digital, are one of a kind as the technology and hard work has allowed them to minimize the sensor size to only 20x20x3 mm in order for gas sensing to become a part of our everyday lives. The company has foreseen that sensors of all types are going to be integrated into smartphones and other wearable devices, becoming an integral part of our everyday lives and building the Internet of Things (IoT).

IoT low-cost sensors are in my DNA as I believe they will allow us to understand environmental issues otherwise, we would have dismissed or we would not be aware.

Let’s read together what they have to share with us and reach a conclusion at the end.

Interview

  • Tell us a bit about your motivation in developing air quality sensors?

We saw the need and opportunity for low cost electrochemical sensors with good performance – before SPEC, high performance sensors were too expensive and too big to enable new applications in wearables and distributed monitors. SPEC was born out of the research driven by Eco Sensors / KWJ Engineering, Inc. led by Dr. Joseph Stetter.  We were able to build SPEC Sensors using modern technology in a new high performance plastic package.Read More »

What should schools do to prevent the spread of SARS-CoV-2 in classrooms

Sotirios Papathanasiou6 Comments

Masks provided decent protection against the SARS-CoV-2 but if a carrier of the virus (40% of them are asymptotic) stays inside a home/business for a long time then the chances of transmitting the virus are higher because some particles may escape.

According to experts the best way to prevent the spread of the virus is to keep introducing fresh air inside a room.

Unfortunately, most rooms don’t meet the recommendation of 8 air changes an hour for a 10 square meter (107 square foot) room occupied by 4 people. A clear example is a classroom that doesn’t meet the recommended ventilation rates. This is a common mistake across all schools in the world.

Next Air Quality Monitor

Sotirios Papathanasiou3 Comments

Each year around this time I write a post about what’s next in the industry of air quality.

I have been receiving a lot of emails and I have held meetings with many companies around the world that are interested to know what it has to be done in order to succeed.

Hear me out, there are a lot of companies right now and all of them are trying to do the same thing, to build an AQ Monitor that already exists. Customers are constantly telling us what they want, you don’t listen to them, but I do.
