Pyreos, the Edinburgh-based infra-red sensor developer and manufacturer, has revealed that its ezPyro chip is being used by South Korean firm Trueyes to make the world’s smallest pyro-electric flame-sensing module.

Trueyes’ TF100 module measures just 16mm by 16mm and provides highly-sensitive flame detection at a distance of up to 35 metres. The TF100 has a field of view of more than 90 degrees, with a quick response time and low power consumption.

Trueyes’ new module will be used to add flame-detection capabilities into cameras, thermal imaging equipment, motion detectors and IoT devices. Target markets include devices for homes, factories and warehouses in China, Japan and Korea.

Do Hyung Kim, vice president and co-founder of Trueyes, said: “The ezPyro solution from Pyreos not only allows us to build a very small flame sensing module, but also enables a flexible platform to tailor the TF100 module to meet the specific requirement of the different end user applications.”

Andrew Wallace, CEO at Pyreos, added: “This is an exciting implementation of our ezPyro product.”

“Whilst this particular application doesn’t fully utilise ezPyro’s low-power capabilities, the small size and the programmability of the device ensures that end customers can optimise their products to meet their requirements.”

“We are looking forward to new flame and gas detection modules being launched based on our ezPyro family of products.”

Pyreos launched its ezPyro chip at the Sensor+Test measurement fair at Nuremburg in Germany in May 2016.

The ezPyro chip is the world’s smallest pyro-electric sensor with a digital interface.

The component can be used in a wide range of applications, from flame and gas detection through to motion and gesture sensors in wearable devices.

News of the launch of Trueyes’ TF100 module comes just days after Pyreos revealed it has secured £1.7m of funding from a syndicate of new investors led by Jon Moulton’s family office, Perscitus, alongside existing shareholders.

The latest investment brings the total raised by Pyreos since 2015 to almost £7m, with existing shareholders including Seraphim Capital, London Business Angels, Robert Bosch Venture Capital GmbH, the Scottish Investment Bank (the investment arm of Scottish Enterprise) and Siemens Technology Accelerator.

Pyreos’ unique technology was originally developed by Siemens, from which Pyreos was spun out in 2007.

The company, which is based at the Scottish Microelectronics Centre in Edinburgh, grew last year’s revenues by 50%, with exports accounting for 81% of sales thanks to growth in major markets including China, Korea, India and the United States.
