AKM officially launches three latest sensors

Recently, Asahi Kasei Microdevices (hereinafter referred to as "AKM") has launched three new sensors: AK9703AJ, AK9730AJ, and AK9723AJ. Among them, AK9703AJ is an infrared light emitting diode (IR LED) whose peak emission wavelength is in the infrared absorption band of methane (a well-known flammable gas); AK9730AJ is an infrared sensor with optical filter and its peak emission The wavelength is also in the infrared absorption band of methane. The above two products are equipped with high-speed drivers, high reliability and small package size, which help reduce the size and power consumption of combustible gas detection systems. The AK9723AJ, which is also on sale, is an infrared sensor AFE IC (analog front-end integrated circuit) equipped with an IR LED driver. The constant current driving conditions of the LED and the gain of the AFE can be changed by software. AK9723AJ also features low current consumption and small package size.

Combining the above three products, non-dispersive infrared (NDIR) combustible gas detection system can be easily configured. It is ideal for easy-to-install applications such as portable flammable gas lower limit detectors and applications such as gas pipeline leak detectors that are powered by solar cells and are easy to install.

AKM has released a series of NDIR CO2 sensors, such as: IR LED, IR sensor and IR sensor AFE IC with LED driver. It is mainly used in air-conditioning systems with built-in CO2 sensors. It is highly efficient and can create a comfortable environment.
