卧室数据采集器——温度、湿度、光照强度、夜间手机使用监控

主要内容：暂定使用ESP8266(MicroPython)完成产品原型，主要用于监测控制夜间手机使用时间，数据传至onenet来综合分析睡眠质量。

5.1 ESP12F引脚功能规划：

TM1637四位数码管 IIC	GPIO4:clk GPIO5:dio
微动按键	GPIO13
蜂鸣器	GPIO16(只能做为输出，不能输入，否则也会引起错误)
板载LED，低电平亮	GPIO2:
BME280大气压强温湿度传感器 MAX44009光照强度传感器 预留HX711称重传感器接口	GPIO12:sda GPIO14:scl

5.2电路绘制

5.3绘制PCB（请忽略板子外形，另有他用。）

5.10先放几张图，下午慢慢写

 

5.17代码已整理好。

已实现功能

TM1637四位数码管 IIC	轮流显示时间（WIFI实现NTP对时）、温度、气压、湿度
微动按键	手机放上状态为0，拿开状态为1，可简单得出夜间手机使用时间。
蜂鸣器	未焊接，准备用来设置手机到时放下，不到时间不准拿起，否则报警。
板载LED，低电平亮	onenet通过命令控制亮灭。
BME280大气压强温湿度传感器 MAX44009光照强度传感器 预留HX711称重传感器接口	只焊接了BME280来监测温度、气压、湿度。 未焊接光强传感器，准备监测室内亮灯状态辅助分析睡眠质量。 未焊接称重传感器，准备通过称重手机质量代替微动按键，精确区分监测主人手机。
