Wio E5 Powered Solar Environmental Node with Qubitro

In this project, we will design and develop a self-sustaining, solar-powered environmental sensor node equipped with the advanced BME680 sensor. 🌞 This versatile sensor is capable of accurately measuring key ecological parameters such as temperature 🌡️, humidity 💧, barometric pressure 📊, and volatile organic compounds (VOC) to assess air quality 🌬️. Powered by a solar panel and optimized for low-power consumption, this system ensures long-term functionality even in remote, off-grid locations. 🌍

To transmit the collected data, the node will employ LoRa (long-range) communication 📡, a highly efficient wireless technology known for its ability to cover vast distances with minimal power. This makes it particularly suitable for applications where traditional connectivity options are either unavailable or unreliable, such as in rural areas, forests 🌳, or disaster-prone zones. 🚨

The node will continuously collect environmental data and send it to a central gateway, where it can be further analyzed, stored, or visualized in real time. 📈 This project holds immense potential for various use cases, including remote climate monitoring 🌦️, agricultural management 🌾, and air quality assessments in hard-to-reach areas. With its sustainable design and robust communication capabilities, this solar-powered sensor node is an innovative solution for advancing environmental monitoring in challenging locations. 🌱

Components Needed:

• Microcontroller: Xiao nRF52840 Sense. 🖥️
• LoRa Module: Wio E5. 📡
• BME680 Sensor: For measuring environmental parameters. 🌡️💧📊
• Solar Panel: 5V or higher, depending on your power requirements. 🌞
• Battery: LiPo battery to store solar energy. 🔋

Step 1: Circuit Diagram :

I have implemented this project with a breadboard using Wio E5, Xiao ESP32S3 Grove Sunlight sensor, and a LiPo battery. 🔋

Xiao nRF52840 Sense:

• Microcontroller: Based on the nRF52840 SoC, it features Bluetooth 5.0, NFC, and various sensors (e.g., IMU, microphone). 🖥️📡🎤
• Size: Ultra-small form factor, making it ideal for compact designs. 📏
• Features: Low power consumption, multiple I/O options, and built-in sensors for additional data collection. ⚡🔌

LoRa Wio E5:

• LoRa Module: Integrates the STM32WLE5JC, which combines an MCU and LoRa transceiver. 📡
• Frequency: Supports global LoRaWAN frequencies. 🌍
• Features: Low power consumption, long-range communication, and easy integration with LoRaWAN networks. ⚡📶

BME680 Sensor:

• Environmental Sensor: Measures temperature, humidity, pressure, and gas levels. 🌡️💧📊
• Interface: I2C or SPI communication. 🔄
• Features: High accuracy, low power consumption, and compact size. 🎯⚡

A breadboard is a reusable platform used for prototyping electronic circuits without soldering. 🛠️ It allows for quick and easy assembly and modification of circuits. ⚡ But we can’t use this as a direct application. So, I planned to build a PCB with all these components. 🖥️

Here is the schematic of the project. 📐

In this schematic, I have used three different components. The first one is Xiao nRF52840 Sense 🖥️, then LoRa Wio E5 📡, and BME680 🌡️💧📊.

Here is the final 3D view of my design. 📐🔍

I have added a solar panel in the backside of the PCB. 🌞🔋 This allows us to directly use this outdoors without any power issues. 🌳🏞️ Also, I have added the grove port to add additional sensors. 🔌📡

Step 3: Board Bring-up:

Once I got my boards, I just verified that is there any visible defects.

Backside view

Next, let's check the assembled PCBs.

Backside view

Then, we need to check for the sensor connections. Here is a simple sketch that can check the I2C sensors.

#include <Wire.h>
 
void setup() {
  Wire.begin();
  Serial.begin(115200);
  Serial.println("\nI2C Scanner");
}
 
void loop() {
  byte error, address;
  int nDevices;
  Serial.println("Scanning...");
  nDevices = 0;
  for(address = 1; address < 127; address++ ) {
    Wire.beginTransmission(address);
    error = Wire.endTransmission();
    if (error == 0) {
      Serial.print("I2C device found at address 0x");
      if (address<16) {
        Serial.print("0");
      }
      Serial.println(address,HEX);
      nDevices++;
    }
    else if (error==4) {
      Serial.print("Unknow error at address 0x");
      if (address<16) {
        Serial.print("0");
      }
      Serial.println(address,HEX);
    }    
  }
  if (nDevices == 0) {
    Serial.println("No I2C devices found\n");
  }
  else {
    Serial.println("done\n");
  }
  delay(5000);          
}

Luckily there are no defects in my design, and my BME680 was detected in the I2C connection.

Next, let's implement the BME680 and Wio E5.

Step 4: BME680 Setup

Install Libraries: Install the BME680 library from the Arduino Library Manager.

Code Example: Here is the simple sketch to get environmental data from the BME680.

#include <Wire.h>
#include <Adafruit_Sensor.h>
#include <Adafruit_BME680.h>

#define SEALEVELPRESSURE_HPA (1013.25)

Adafruit_BME680 bme; // Create an instance of the sensor

void setup() {
  Serial.begin(9600);
  if (!bme.begin()) {
    Serial.println("Could not find a valid BME680 sensor, check wiring!");
    while (1);
  }


  // Set up BME680
  bme.setTemperatureOversampling(BME680_OS_8X);
  bme.setHumidityOversampling(BME680_OS_2X);
  bme.setPressureOversampling(BME680_OS_4X);
  bme.setIIRFilterSize(BME680_FILTER_SIZE_3);
  bme.setGasHeater(320, 150); // 320*C for 150 ms
}

void loop() {
  // Perform a reading
  if (!bme.performReading()) {
    Serial.println("Failed to perform reading :(");
    return;
  }

  // Print data to Serial Monitor
  Serial.print("Temperature = ");
  Serial.print(bme.temperature);
  Serial.println(" *C");

  Serial.print("Humidity = ");
  Serial.print(bme.humidity);
  Serial.println(" %");

  Serial.print("Pressure = ");
  Serial.print(bme.pressure / 100.0);
  Serial.println(" hPa");

  Serial.print("Gas = ");
  Serial.print(bme.gas_resistance / 1000.0);
  Serial.println(" KOhms");

  delay(2000); // Wait for 2 seconds before next reading
}

Here is the serial terminal response for the BME680 example sketch.

Step 5: Wio E5 Setup

Next, let's implement the Wio E5. Here is the simple P2P sketch that can send and receive data.

This above code snippet can send 5 different data to the TTN. 📡🌐 This serial terminal response shows the TTN credentials. 🖥️🔑 Next, we have to add this device to the TTN console application. 📲🛠️

Step 7: TTN setup for the Solar Env Node:

Navigate to the TTN console. Create a new application and an end device.

here is the final TTN setup with live data.

I have used this payload format.

function Decoder(bytes, port) {
  
  var decoded = {};
  if (port === 8) {
    decoded.temp = bytes[0] <<8 | bytes[1];
    decoded.humi = bytes[2] <<8 | bytes[3];
    decoded.pressure = bytes[4] <<8 | bytes[5];
    decoded.gas = bytes[6] <<8 | bytes[7];
    decoded.altitude = bytes[8] <<8 | bytes[9];
  }

  return decoded;
}

Finally, you can see all the complete 5 data in the TTN dashboard.
