ACEBOTT China's New Small Smart Digital Electronic Module Photosensitive Photoresistor Sensor Light Sensor Optical Sensors
Product Description
🔍 Product Overview
Light sensor is a sensor used to detect light intensity, which is used to measure the properties of light in various scenes.
Light sensor is the use of photosensitive resistance resistance will change with the change of light intensity characteristics, when the light shines on the photosensitive resistance, the resistance value is reduced; However, in low light or dark environment, the resistance value increases. By measuring the change of the resistance value, the intensity of the light can be determined.
Application reference: lighting control, photoelectric switch, solar tracking and other scenes that need to sense light.
