The intensity of outdoor light is collected regularly to generate corresponding values The generated real-time light intensity data be reported to the Internet of Things data platform (such as the Tuya platform) It can be used for electric curtains, electric awnings, smart switches, smart sockets and other equipment; it can be used to realize smart perception of household lights, agricultural awnings and other functions. operational principle: The is collected by digital photosensitive IC chip and converted into digital signal. The digital signal is converted into unit value of light by module loading algorithm Report to the Internet of Things platform (such as Tuya Smart Platform, etc.) through the Internet of Things module (such as WIFI, ZIGBEE, Mesh, etc.) After the Internet of Things platform collects the light value, it sends the data to other controlled devices in the platform (such as smart light bulbs, smart switches, smart curtains, etc.) according to the automation conditions set by the APP user. After receiving the signal, the controlled devices perform actions according to the automation conditions set by the user APP (such as turning off lights, turning on lights, etc.) The APP user can directly view the current light intensity value through the APP Color: White Material: plastic Package Contents: 1 * Solar Light Sensor Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
