Industry’s smallest and fastest SMD sensor – a low-cost dual channel pyroelectric device

Pyreos has announced the launch of the world’s first dual-channel SMD (surface mount) pyroelectric sensor – ezPyroTM SMD Dual.

The dual-channel sensor extends the digital ezPyro range, which is the world’s smallest and fastest pyroelectric sensor, combining a high sensitivity with benefits such as low power consumption, built-in power management, simple integration, a digital interface and the cost-effectiveness of SMD.

The dual-channel ezPyro sensor couples two unique, thin-film PZT pyroelectric elements – separated by just 2mm.  This small distance makes it easier to focus IR energy on both elements in a simple optical and energy-efficient design. It also ensures that both elements are in near-identical environments, giving the best possible reference compensation.  The integrated digital package reduces detector cost and component count/cost whilst increasing the performance of customers’ modules.

Applications in gas detection include carbon dioxide (CO2), methane (CH4) and hydrocarbons, refrigerants, nitrogen oxides (NOx) and sulphur oxides (SOx).  The product can also be used in certain flame detection applications.

The ezPyro SMD Dual is compatible with the complete ezPyro evaluation and development ecosystem, sharing the integrated read-out circuitry and an I2C digital communications bus, APIs and sampling synchronisation with emitters and other detectors. This virtually eliminates development barriers for customers familiar with ezPyro SMD or ezPyro TO products when evaluating and designing this solution.  See for more information.

“The addition of this new dual-channel sensor builds on the industry-leading technology used in our ezPyro SMD pyroelectric range,” said Andrew Wallace, CEO at Pyreos. “It delivers the thermal and mechanical stability over many years of operation that the existing range is known for, yet it gives even better results in some key applications where SNR and reference comparisons are critical.”

Samples can be ordered now from (reference ES2574 for CO2, ES2627 for enhanced Methane CH4). The evaluation kit with PC software that enables sensor configuration, signal visualisation and capture-to-file is also available.

Pyreos will be showing prototypes of the new product range at the Sensor and Test Show in Nuremberg, 25-27 June 2019, Hall 5 – stand 242.
