Gas Sensor Innovation - GSS Now from Elgood!


Ultra-Low-Power CO2 Sensor from Gas Sensing Solutions

CozIR®-LP3 CO2 is a sensor with <3.5mW average power consumption, low-profile and form factor and multiple fixturing options.

About the CozIR®-Blink

The CozIR®-Blink is an ultra-low power NDIR CO₂ sensor using state-of-the-art solid-state LED optical technology. The low-power LEDs are manufactured in-house, giving GSS complete control of the CO₂ sensor signal chain.

The CozIR®-Blink uniquely allows users to reduce the power consumption of CO₂ measurements to unprecedented levels. The CO₂ sensor is designed to be power-cycled, where the user wake-ups the sensor, take a reading, and then powers it down again, reducing power consumption to a minimum. The power cycling function is particularly valuable in battery-powered or wirelessly connected interface applications where power is at a premium.

The CozIR®-Blink also features a built-in auto-calibration function that maintains CO₂ measurement accuracy over the lifetime of the product.
