- Step S113 Turn on a light source when the intensity of the current ambient light is less than a preset first intensity threshold, and the sensing device uses a light signal emitted by the light source to perform biological work on a target object that approaches or touches the sensing device. Sensing of feature information.
- step S113 further includes: according to the current The intensity of the ambient light corresponds to the intensity of the light signal emitted by the light source. Specifically, the stronger the current ambient light intensity is, the greater the intensity of the light signal emitted by the light source is; the weaker the current ambient light intensity is, the less the intensity of the light signal emitted by the light source is reduced.
- the ambient light is strong, the light signal that penetrates the finger is relatively strong.
- the controller 320 is further configured to: when performing the sensing of the biometric information, call an external light sensor to perform a light sensing operation, and receive the intensity of the current ambient light acquired by the external light sensor.
- the biometric information sensing device 300 can be applied to an electronic device provided with a light sensor, and the controller 320 has a calling interface, and when the sensing of the biometric information is performed, the light sensor of the electronic device is called by calling the interface. Sensing data to obtain the intensity of the current ambient light based on the photographic data.
- the ambient light intensity is sensed by using an external light sensor, thereby saving the cost of additionally setting the light sensor.
- the biometric information sensing device 300 further includes a package housing 350 for packaging the sensing unit 310 and the light source 340.
- the package housing 350 can also package components such as the controller 320 together.
