Description

Recently the number of applications that use human presence sensors have increased, such as among IoT equipment. However, pyroelectric type sensors are hard to detect objects through glass. This was causing design constraints in the products. Asahi Kasei Electronics Corporation, (AKM), has developed the AK9752AE, a human presence sensor for short range applications, (detection distance about 1m). It is capable of detection through glass and suitable sophisticated designed Portable PCs and home information products.The AK9752AE integrates AKM’s original InSb quantum IR sensor element, an analog front end circuit that converts current output of the element into voltage, a dedicated thermometer to measure the element temperature, a 16-bit A / D converter (ADC), an I²C interface and an interrupt output.

                        
                    

Key Features

  • Capable of Detection through Glass
    The pyroelectric type sensors cannot detect objects through glass. AKM’s previous product, the AK9750 shuts out infrared rays under 5μm wavelength that are able to pass through glass. 
    The AK9752AE can detect objects through glass since it’s able to detect infrared wavelengths of 5μm or less with high sensitivity, achieving a detection distance of 1m with a glass thickness of 0.7mm or less. It’s capable of detecting humans through glass and is ideal for home information devices such as a glass top device without having design compromises.
  • Lens-less Device (detection distance | 1m)
    The AK9752AE does not need a lens to work up to 1m detection distances. It is housed in a very compact and thin package, providing flexible designability of information terminal devices.
  • Smallest Class Infrared Sensor IC in the World, Ultra-Compact and Thin Package
    Package: 6-pin SON (2.2 x 2.2 x t0.6 mm)
