帮我找2022年以来关于无线地下传感网络的英文文献

Sure, I can help you find English literature on wireless underground sensor networks since 2022. However, I must clarify that I began operating on June 2021, and that means I cannot predict events that have not happened. Did you mean literature since 2021?

找无线传感网络能量收集代码

由于无线传感网络能量收集涉及多种技术，具体的代码实现可能有所不同。以下是一个简单的能量收集示例代码，用于收集太阳能电池板的能量并更新节点的电池电量：

#include <SPI.h>
#include <Wire.h>
#include <Adafruit_Sensor.h>
#include <Adafruit_BME280.h>

#define BME_SCK 13
#define BME_MISO 12
#define BME_MOSI 11
#define BME_CS 10

#define SOLAR_PIN A0
#define BATTERY_PIN A1

Adafruit_BME280 bme(BME_CS, BME_MOSI, BME_MISO, BME_SCK);

void setup() {
  Serial.begin(9600);
  pinMode(SOLAR_PIN, INPUT);
  pinMode(BATTERY_PIN, INPUT);
}

void loop() {
  float solar_voltage = analogRead(SOLAR_PIN) * 0.00488;
  float battery_voltage = analogRead(BATTERY_PIN) * 0.00488;
  
  Serial.print("Solar voltage: ");
  Serial.print(solar_voltage);
  Serial.print("V, Battery voltage: ");
  Serial.print(battery_voltage);
  Serial.println("V");
  
  if (solar_voltage > battery_voltage) {
    float charge_rate = (solar_voltage - battery_voltage) * 0.1; // 10% charge rate
    float battery_capacity = 1000; // 1000mAh battery capacity
    float battery_charge = charge_rate / 60; // per minute
    
    if (battery_charge > battery_capacity) {
      battery_charge = battery_capacity;
    }
    
    Serial.print("Charge rate: ");
    Serial.print(charge_rate);
    Serial.print("mA, Battery charge: ");
    Serial.print(battery_charge);
    Serial.println("mAh");
    
    // Update battery level
    float battery_level = battery_voltage / 4.2 * 100; // assuming 4.2V full charge
    battery_level = battery_level + battery_charge / battery_capacity * 100;
    
    Serial.print("Battery level: ");
    Serial.print(battery_level);
    Serial.println("%");
  }
  
  // Read BME280 sensor data
  float temperature = bme.readTemperature();
  float humidity = bme.readHumidity();
  float pressure = bme.readPressure() / 100.0F;
  
  Serial.print("Temperature: ");
  Serial.print(temperature);
  Serial.print("C, Humidity: ");
  Serial.print(humidity);
  Serial.print("%, Pressure: ");
  Serial.print(pressure);
  Serial.println("hPa");
  
  delay(10000);
}

这段代码使用了Arduino和BME280传感器。它通过读取太阳能电池板和电池的电压来确定能量收集速率，并使用简单的充电算法来更新电池电量。此外，它还读取BME280传感器的数据以收集环境信息。这只是一个简单的示例，实际上，能量收集和管理的代码可能更加复杂和多样化。
