NodeMCU 12E esp 8266深度睡眠的功耗问题求解

我正在使用 NodeMCU 12E esp8266，我连接到 Wifi，在 GPIO 2 上测量温度，将它发送到数据库，然后我用这个命令 ESP.deepSleep(1200e6) 进入睡眠状态。功耗始终在 77mA 左右，数据表显示功耗应在 20 毫安培左右。请帮忙。
电路板进入深度睡眠 20 分钟并唤醒，没问题，但深度睡眠中的功耗是个问题。这是代码：
代码：全选#include
#include
#include "ESP8266WiFi.h"
#include
#include

const char* ssid = "njka Local";
const char* password = "!3bNwjSf9";

const char* serverName = "http://controltemp.online/emmezeta/connect_dako.php";

String sensid = "dse1p2";

const int oneWireBus = 2;

OneWire oneWire(oneWireBus);

DallasTemperature sensors(&oneWire);

void setup() {
  Serial.begin(115200);

  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED)
  {
     delay(500);
     Serial.print("*");
  }

  sensors.begin();

  sensors.requestTemperatures();
  float temperatureC = sensors.getTemPCByIndex(0);

  if(WiFi.status()== WL_CONNECTED){

    HTTPClient http;

    http.begin(serverName);

    http.addHeader("Content-Type", "application/x-www-form-urlencoded");

    String httpRequestData = "&sensid=" + sensid + "&temp1=" +
String(temperatureC) + "";
    Serial.print("httpRequestData: ");
    Serial.println(httpRequestData);

    int httpResponseCode = http.POST(httpRequestData);

    if (httpResponseCode>0) {
      Serial.print("HTTP Response code: ");
      Serial.println(httpResponseCode);
    }
    else {
      Serial.print("Error code: ");
      Serial.println(httpResponseCode);
    }
    // Free resources
    http.end();
  }
  else {
    Serial.println("WiFi Disconnected");
  }
  //Send an HTTP POST request every 20 minutes
  ESP.deepSleep(1200e6, WAKE_RF_DEFAULT);
}

void loop() {

}
