Pyreos sensors distributed by GVZ

Pyreos launches of the world’s first dual-channel SMD (surface mount) pyroelectric passive infra-red 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.

Compared with other pyroelectric and thermopile sensors, the ezPyro SMD family has high sensitivity, faster response, fast switch-on, lower power consumption, more on-the-fly configurability, lower component counts and easier integration which makes the ezPyro™ SMD a unique solution for gas, flame, motion and gesture detection. Applications in gas detection include carbon dioxide (CO2), methane (CH4) and hydrocarbons, refrigerants, nitrogen oxides (NOx) and sulphur oxides (SOx).

The evaluation kit with PC software that enables sensor configuration, signal visualisation and capture-to-file is also available. Moreover, 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.

Pyroelectric sensor with unique power management

ezPyro™ is well suited to applications with low power budgets. Current consumption is well below 100 µA when fully activated and less than 1 µA in the lowest power mode. The low power modes come with fast wake up times and the innovative and configurable wake-up by signal feature for motion & gesture.

Synchronised readout of multiple infrared sensors

Operating up to the FM+ I2C standard with clock speeds up to 1 MHz allows 4 or more sensors configured on the same bus. Each available channel can be individually configured using several variable filters. Another unique feature is that the sampling of multiple ezPyro sensors can easily be synchronized by distributing the clock signal of one ezPyro™ device to one or more others (“daisy-chaining”).

Optical filter configurations

ezPyro SMD Dual prototypes can be offered with various optical filters. Please inquire our Service Team regarding your IR sensing project needs.
