Digital pyro-electric sensor is surface mount for optical efficiency
Pyreos is shipping prototypes of its surface mount, dual channel pyro-electric sensor for gas, flame and analysis. The ezPyro SMD Dual sensor can access software and hardware components of the Pyreos development ecosystem.
The small, fast ezPyro SMD Dual collocates sensors integrates two thin film PZT pyro-electric elements separated by just 1.6mm inter-pixel distance (IPD). The small IPD means that two channels can be measured by illuminating an area that measures just 2.8mm across, for an energy-efficient design, says Pyreos.
The ezPyro reduces costs, claims Pyreos. The digital readout reduces system component count/cost while the integration of two channels further reduces cost and space, claims the company. The lower IPD and reduced component count enables a physically smaller design which saves cost and energy demand.
ezPyro SMD Dual has a widened range of gas detection options. It can detect carbon dioxide (CO2), methane (CH4) and hydrocarbons, refrigerants, nitrogen oxides (NOx), and sulphur oxides (SOx). In addition to an expanded range of gas sensing, the ezPyro SMD Dual sensor analyses foods including fats, sugars, proteins, alcohol and acidity.
The ezPyro SMD Dual combines high sensitivity with benefits such as low power consumption, built-in power management, a digital interface with plug-and-play connectivity to microcontrollers, and the cost-effectiveness of SMD design. It is compatible with the ezPyro evaluation and development ecosystem and shares the integrated read-out circuitry and an I2C digital communications bus.
The fast development cycle of the ezPyro sensor family is supported by evaluation kits for flame, gas, motion and gesture detection. Other applications can be trialled using the ezPyro SMD prototyping system which supports up to four sensor breakout boards. Sensor evaluation without any software development effort is enabled by Pyreos PC software.
ezPyro is suitable for low power applications with a current consumption below 50 microA when fully activated and less than 1 microA in the lowest power mode.
Samples and evaluation kits are available.
Pyreos was formed in 2007, to specialise in miniature, rugged, pyro-electric, mid-infrared sensors and detectors that respond faster, improve response and minimise power consumption. The thin-film sensor components detect and analyse composition in gas, flame, food safety and oil applications and enable the creation of smaller, higher-performance IR sensors, sensor modules and analysers which are easier to develop and need less calibration.
