Abstract

The invention discloses a sensing device for detecting environmental factors and a method for using the same. The sensing device detects environmental factors and generates current according to the environmental factors, and the environmental factors include visible light, light to be measured, other light and environmental temperature; The sensing device includes: a first sensor that detects and generates a first current according to environmental factors including the light to be measured; a second sensor that detects and generates a second current according to environmental factors excluding the light to be measured; The first current and the second current are calculated to obtain a reading circuit of the photocurrent to be measured that reflects the intensity of the light to be measured. Eliminate the interference of other factors, and measure the accurate light intensity of the light to be measured.

Description

technical field

[0001] The invention relates to the technical field of sensors, in particular to a sensing device for detecting environmental factors and a method for using the same. Background technique

[0002] A photoelectric sensor is a sensor that uses a photoelectric element as a detection element. It first converts the measured change into a change of optical signal or directly detects the optical signal in the environment, and then further converts the optical signal into an electrical signal by means of a photoelectric element.

[0003] Photoelectric sensor is a key component to realize photoelectric conversion in various photoelectric detection systems. It is a device that converts optical signals (visible, infrared and ultraviolet laser light) into electrical signals; photoelectric sensors are sensors that use photoelectric devices as conversion elements. It can be used to detect non-electric physical quantities that directly cause changes in light quantity, such...
