<h3 style="line-height:1.8;"><span style="font-size:18pt;"> 1、项目简介</span></h3> <hr> <p style="line-height:1.8;"><span style="font-size:18pt;">1.盛思锐SHT40是一个数字传感器平台，可用于对不同的精度测量相对湿度和温度。其I2C接口提供多个预配置的I2C地址，同时保持超低功耗（0.4μW）。功率微调的内部加热器可用于三个加热级别，从而实现传感器在苛刻的环境中运行。四针双扁平无引线封装适用于表面安装技术（SMT）处理，包括可选的封装专利PTFE膜或可拆卸的保护盖。符合ISO17025的传感器特定校准证书，可识别通过唯一的序列号。</span></p> <p style="line-height:1.8;"><span style="font-size:18pt;">2.使用STM32G030K6T6芯片作为主控芯片，该芯片使用Arm Cortex-M0+内核；最大主频64Mhz；具有32KB的Flash以及8K的SRAM。</span></p> <p style="line-height:1.8;"><span style="font-size:18pt;">3.项目使用该传感器作为温湿度采样传感器，STM32G030K6T6芯片作为主控芯片。</span></p> <h3 style="line-height:1.8;"><span style="font-size:18pt;">2、项目属性</span></h3> <hr> <p style="line-height:1.8;"><span
