CozIR-Blink Sensor

March 9, 2021
GSS' lowest power CO2 sensor enables users to manage power consumption based on their needs and application.

The CozIR-Blink CO2 sensor is GSS' lowest power CO2 sensor yet and is the lowest power consumption NDIR CO2 sensor available on the market. This ultra-low-power carbon dioxide sensor enables the user to manage power consumption based on their needs and application.


The Blink Mode allows users to customize how much energy is spent on each measurement, putting you in full control of energy trade-offs for ultra-low power applications. The sensor can be turned on to record a reading, and then powered off completely when not in use. This is not a sleep mode—the sensor uses no power during this stage. Its low power consumption also makes it ideal for battery-powered systems, including IoT applications and smart technology as it only requires 3.3 V. The sensor is easy to use and comes with both I2C and UART interface.


The CozIR-Blink is part of the CozIR range of CO2 sensors which have been designed for low concentration carbon dioxide environments. Measurement ranges are offered in 0 to 2,000ppm, 0 to 5,000ppm, and 0 to 1%.
