SEN00390

简介

这款环境光传感器设计新颖,外壳采用透明的半球封装形式,可以更好的聚光而采集光照。该传感器拥有0-200klx的检测范围,采用I2C通信,兼容Arduino、esp32等多种控制器。针对人眼对环境光的响应,结合红外和紫外屏蔽,优化了片上光电二极管的光谱响应,自适应增益电路自动选择正确的流明范围优化测试(计数值/流明)。可用于智能灯、汽车智能灯、智能孵化器、农业、仪器仪表等。

光亮度数据参考:

注意

这是一种感应器,能获得光的强度。
它使用I2C传输采集到的数据,其IIC地址不能改变。
您可以将所需的配置写入配置寄存器(地址:0x04),设置不同的获取精度。
您可以从数据寄存器读取光强数据(地址:0x00~0x03)。 
这个传感器采用软件I2C封库,不能与其它采用硬件I2C的设备或传感器一起使用。
