Flexible Face Shield Mask Component Documentation
The Flexible Face Shield Mask is a wearable IoT component designed to provide real-time monitoring of environmental pollutants and air quality. It features a flexible, breathable mesh material, allowing for comfortable wear while maintaining a high level of protection. The mask is equipped with advanced sensors to detect particulate matter (PM), nitrogen dioxide (NO2), and ozone (O3) levels.
Dimensions: 150mm x 100mm x 20mm
Weight: 50g
Sensor Accuracy: 5% for PM, NO2, and O3
Power Supply: Rechargeable Li-ion battery (up to 8 hours of continuous use)
Communication Protocol: Bluetooth 5.0
Operating Temperature: -20C to 40C
Example 1: Air Quality Monitoring with Arduino
In this example, we'll demonstrate how to connect the Flexible Face Shield Mask to an Arduino board to monitor air quality levels.
```c++
#include <Wire.h> // For I2C communication
#include <BLE.h> // For Bluetooth communication
// Define the pin connections
#define PM_SENSOR_PIN A0
#define NO2_SENSOR_PIN A1
#define O3_SENSOR_PIN A2
// Initialize the mask's Bluetooth module
BLE ble;
void setup() {
Serial.begin(9600);
ble.begin("FlexibleFaceShieldMask");
ble.setDeviceName("AirQualityMonitor");
}
void loop() {
// Read sensor values
int pmValue = analogRead(PM_SENSOR_PIN);
int no2Value = analogRead(NO2_SENSOR_PIN);
int o3Value = analogRead(O3_SENSOR_PIN);
// Convert sensor values to PPM (parts per million)
float pmPpm = pmValue (5.0 / 1023.0);
float no2Ppm = no2Value (5.0 / 1023.0);
float o3Ppm = o3Value (5.0 / 1023.0);
// Print air quality data to serial monitor
Serial.print("Air Quality Data: ");
Serial.print("PM: ");
Serial.print(pmPpm);
Serial.print(" PPM, NO2: ");
Serial.print(no2Ppm);
Serial.print(" PPM, O3: ");
Serial.print(o3Ppm);
Serial.println(" PPM");
// Send data to mobile app via Bluetooth
ble.sendData(pmPpm, no2Ppm, o3Ppm);
delay(1000);
}
```
Example 2: Integration with a Mobile App (Android) using Kotlin
In this example, we'll demonstrate how to connect the Flexible Face Shield Mask to an Android mobile app using Kotlin to display real-time air quality data.
```kotlin
import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import android.bluetooth.BluetoothAdapter
import android.bluetooth.BluetoothDevice
import android.bluetooth.BluetoothGatt
import android.bluetooth.BluetoothGattCharacteristic
import android.bluetooth.BluetoothManager
class AirQualityActivity : AppCompatActivity() {
private lateinit var bluetoothAdapter: BluetoothAdapter
private lateinit var bluetoothGatt: BluetoothGatt
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_air_quality)
// Initialize Bluetooth adapter
bluetoothAdapter = BluetoothAdapter.getDefaultAdapter()
// Scan for nearby devices
bluetoothAdapter.startLeScan(deviceCallback)
}
private val deviceCallback = object : BluetoothAdapter.LeScanCallback {
override fun onLeScan(device: BluetoothDevice, rssi: Int, scanRecord: ByteArray) {
if (device.name == "FlexibleFaceShieldMask") {
// Connect to the mask
bluetoothGatt = device.connectGatt(this@AirQualityActivity, false, gattCallback)
}
}
}
private val gattCallback = object : BluetoothGattCallback() {
override fun onServicesDiscovered(gatt: BluetoothGatt, status: Int) {
// Get the air quality data characteristic
val airQualityCharacteristic = gatt.getService(UUID.fromString("org.bluetooth.service.air_quality")).getCharacteristic(UUID.fromString("org.bluetooth.characteristic.air_quality_data"))
// Read air quality data
gatt.readCharacteristic(airQualityCharacteristic)
}
override fun onCharacteristicRead(gatt: BluetoothGatt, characteristic: BluetoothGattCharacteristic, status: Int) {
// Process air quality data
val pmValue = characteristic.getIntValue(BluetoothGattCharacteristic.FORMAT_UINT16, 0)
val no2Value = characteristic.getIntValue(BluetoothGattCharacteristic.FORMAT_UINT16, 2)
val o3Value = characteristic.getIntValue(BluetoothGattCharacteristic.FORMAT_UINT16, 4)
// Update UI with air quality data
runOnUiThread {
airQualityTextView.text = "Air Quality: PM=$pmValue, NO2=$no2Value, O3=$o3Value"
}
}
}
}
```
