ESP8266系列文章目录
经过不断的努力，处女作终于出来了。Arduino
带有一个SSD1306 OLED显示电压、电流、功率、温度的屏幕，BLINKERapp检查电压、电流、功率mah、Wh、峰值功率、运行时间、功率比、环境温度、环境湿度、控制器温度、控制器温度控制散热风扇(可在APP检查实时转速)。低电压报警，电池低电压自动切断电压输出APP查看状态)和图标功能。App端文字的颜色可以根据参数自动变化，图标也可以根据参数变化(用了很多if语句。 按刷新健对APP刷新数据。 刚上电截图时，需要放电一次开发板复位，然后开始充电。我用监控24V三元锂18650电池20并6串，满电25.2V。
电比可以根据个人想要的方式改变公式。我的设计容量是1万Wh,所以除1000。
也可以用电压来计算比例，看个人喜好。
ta=Da/1000*100;
2、硬件
ESP8266开发板一块，SSD1306屏幕（0.96寸IIC接口）、INA226电压电流检测模块（IIC接口)，双向电流，我选择的采样电阻0.002Ω卖方声称最大能承受20A，最大电压36V、dht11温湿度传感器，10K电阻 10K热敏电阻(用于A0 ADC接口测温)，所有硬件都没有拍照。
3、硬件连接
将INA226的SCL、SDA与开发板分开D1、D2连接；将SSD1306的SCL、SDA与开发板分开D5、D6连接；两个模块都支持3.3V在开发板上直接供电。将DHT11单总线通信口和开发板D7连接。温敏电阻直接分压电路ADC 开发板A0接口(开发板内置分压电路，核心板ADC接口不会超1V,因此，外部分压电路也可以从开发板取电，无需直接设计）.3V，一些电路图来自网络，以节省绘图时间。开发板D8用于控制MOS管开断实现输出低压保护，开发板D3用于PWM输出控制MOS控制散热风扇。
下图为INA226测量端接线图。
4、程序编写
需要额外下载的库文件：INA226.h、U8g2.h、DHT11.h后两者可以直接存在Arduion内部下载开发软件。
1.整体框架是BLINKER WiFi这里就不写结构了。
2、读取DHT11数据
float h = dht.readHumidity(); float t = dht.readTemperature(); if (isnan(h) || isnan(t)) { BLINKER_LOG("Failed to read from DHT sensor!"); } else { BLINKER_LOG("Humidity: ", h, " %"); BLINKER_LOG("Temperature: ", t, " *C"); humi_read = h; temp_read = t; } //DHT11读温湿度3、读ADC接口数据并转换为温度(监测控制器温度)。
float ADCvalue; float Resistance; ADCvalue = analogRead(NTCPin); Serial.print("Analog value "); Serial.print(ADCvalue); Serial.print(" = "); //convert value to resistance Resistance = (1023 / ADCvalue) - 1; Resistance = SERIESRESISTOR / Resistance; Serial.print(Resistance); Serial.println(" Ohm"); float steinhart; steinhart = Resistance / NOMINAL_RESISTANCE; // (R/Ro) steinhart = log(steinhart); // ln(R/Ro) steinhart /= BCOEFFICIENT; // 1/B * ln(R/Ro) steinhart = 1.0 / (NOMINAL_TEMPERATURE 273.15); // (1/To) steinhart = 1.0 / steinhart; // Invert steinhart -= 273.15; // convert to C //steinhart = steinhart * 1.8 32; // convert to F Serial.print("Temperature "); Serial.print(steinhart); Serial.println("°C"); tem11=steinhart;4.这是在回调函数中使用的IF写不同的情况APP发送不同的图标、不同的颜色文本、文本和数据。
