Pyreos, the Edinburgh-based passive infrared sensor developer, is unveiling a modular prototyping system that will make it easier and faster for customers to develop digital applications around its ezPyro sensor family.
The prototyping system will allow clients to quickly build prototypes that incorporate ezPyro sensors, the world’s smallest pyroelectric sensors with a digital interface.
The ezPyro sensor is the world’s smallest pyroelectric sensor with a digital interface.
Applications range from flame and gas detection through to sensing the direction of human motion and recognizing hand gestures for wearable devices and the internet of things (IoT).
The new prototyping system consists of a STM32 Cortex-M4 based control board, which allows any combination of up to four ezPyro sensor breakout boards to be connected using standard flat ribbon cables.
A USB connection to a PC allows the ezPyro control software to configure and read the connected sensors and log or visualise their data output.
Breakout boards feature ezPyro digital sensors mounted on small printed circuit boards that measure just 16mm by 13.8mm and are only 9mm high.
Breakout boards are available for every sensor in the ezPyro family.
This includes a sensor with a broadband filter that allows customers to use their own custom optical bandpass filters.
EzPyro breakout boards can also be connected directly to any microcontroller with an I2C interface.
The launch of the modular prototyping system follows the unveiling of an ezPyro open API, an embedded software library that allows customers to work with ezPyro mid-infrared sensors at the software level.
Andrew Wallace, chief executive at Pyreos, said: “In today’s fast-moving marketplace, customers need tools to speed-up their product development process.
“The ezPyro modular prototyping system and the open ezPyro API are examples of tools that give our customers a competitive edge in rapid evaluation and prototyping using our innovative digital infrared sensors for gas, flame, motion and gesture sensing.”
Launched at the 2016 Sensor+Test fair held at Nuremburg in Germany, the ezPyro sensor has already secured its first volume design-ins.
The ezPyro comes in an SMD package measuring just 5.65mm by 3.7mm, with a height of 1.55mm, and combine 1 or 4 sensor elements with a readout IC with an I2C interface.
Current consumption ranges from 1μA to 70μA depending on the power mode used, compared with figures measured in mA for similar products.
The chip’s very low-power consumption means that it is very suitable for battery-powered detectors.
ezPyro sensors are very stable and can therefore go without re-calibration for years, thereby significantly reducing the cost of ownership of detectors.
Pyreos is attending the 2017 Sensor+Test trade show in Nuremburg between 30 May and 1 June and can be found in Hall 5 on stand 231. Visitors can make an appointment in advance here.
