App users can directly view the current light intensity value through the app. Tuya Smart ZigBee Solar Brightness Sensor: Uninterrupted Solar Power Range: 0-83,000 LUX, Ultra-Low Power Consumption Solar-powered, cyclically rechargeable; built-in battery powered when the sun is not shining One day of strong sunlight provides over a year of battery life, eliminating the need for battery replacement Regularly collects outdoor light intensity and generates corresponding values. The generated real-time light intensity data is reported to IoT data platforms (such as the Tuya platform). It can be used for devices such as electric curtains, electric awnings, smart switches, and smart sockets; it enables intelligent sensing for household lamps and agricultural awnings. Operating Principle: A digital photosensitive IC chip collects natural light and converts it into a digital signal. The digital signal is converted into light unit values using a module-loaded algorithm. This data is reported to IoT platforms (such as the Tuya Smart Platform) via IoT modules (such as Wi-Fi, ZigBee, and Mesh). Color: As Shown Material: ABS Package Contents: 1 x 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.
