简介

本驱动为 Vishay VEML6075 紫外线传感器提供 MicroPython 支持。VEML6075 是一款高精度 UVA/UVB 传感器，内置信号处理电路，支持可见光和红外补偿，可直接输出校准后的 UV 指数，适用于气象站、可穿戴设备、智能家居等应用场景。

主要功能

• 读取校准后 UVA、UVB 计数值
• 计算并输出 UV 指数（UV Index）
• 可配置积分时间（50/100/200/400/800 ms）
• 支持高动态范围（HD）模式
• 支持可见光和红外补偿系数自定义
• 提供标准版（veml6075.py）和低内存版（veml6075_lowmem.py）两种实现
• 直接 I2C 接口，无需外部依赖库

硬件要求

推荐测试硬件： - Raspberry Pi Pico / Pico W - ESP8266 / ESP32

软件环境

• 固件版本：MicroPython v1.23.0 或更高版本
• 驱动版本：v0.0.1
• 依赖库：无（纯 MicroPython 标准库实现）
