What makes AKM different?

The design conditions required for gas sensors, such as target gas, optical path length, enclosure size, power consumption, response, and interface, vary depending on the application.

By providing components such as light sources and sensors required for NDIR gas sensors, AKM contributes to sensor development tailored to customer specifications. When you want to optimize the optical system and circuit configuration to match your specifications, rather than simply incorporating a ready-to-use module, flexible development is possible at the component level.

For air quality monitors, air conditioning equipment, portable devices, and battery-powered devices, miniaturization and low power consumption of the sensor section are important.

AKM’s infrared photodiodes feature optical filters optimized for the absorption wavelength band of the target gas, supporting optical design for NDIR gas sensors at the component level. High-sensitivity, fast-response photodiode elements and compact, low-profile surface-mount resin-molded packages help enable compact, low-power gas sensing designs with limited mounting space and power conditions.

By considering them together with infrared LEDs and AFE ICs with built-in LED drivers, it becomes easier to design a sensor configuration that includes light emission, detection, and signal processing.

In the development of NDIR gas sensors, it is important to combine, according to the application, the light source that emits infrared light, the detector that detects infrared light after it passes through the gas, and the analog front end that handles small signals.

AKM offers a lineup of infrared LEDs, infrared photodiodes, and AFE ICs with built-in LED drivers, enabling the key elements of NDIR gas sensors to be considered at the component level, from light source driving to detector signal processing.

The value of AKM’s sensor components is that the main components required for NDIR gas sensors can be considered together, rather than sourcing and combining each component individually.
