Hi guys. I want to share my BME680 Indoor AIR Quality monitoring project with yours.
How sensing solutions help to fight against the spread of COVID-19
Parts you need:
- BME680 Module
- ESP8266 Nodemcu or D1 Mini
Arduino Library’s you need:
https://github.com/adafruit/Adafruit_BME680
https://github.com/adafruit/Adafruit_Sensor
Wiring:
The Sketch: ( always I build my blynk sketch with local server )
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
#include <Wire.h>
#include <Adafruit_Sensor.h>
#include "Adafruit_BME680.h"
#define SEALEVELPRESSURE_HPA (1013.25)
Adafruit_BME680 bme;
BlynkTimer timer;
char auth[] = "1ba32e9c834340ed83a795c083c03c4a";
char ssid[] = "MikroTik Tesla";
char pass[] = "12345678";
char server[] = "10.5.51.5";
void setup()
{
Blynk.begin(auth, ssid, pass, server, 8080);
bme.begin();
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
timer.setInterval(2000L, bme680);
}
void bme680()
{
float Temperature = (bme.temperature);
Blynk.virtualWrite(V1, Temperature);
float Humidity = (bme.humidity);
Blynk.virtualWrite(V2, Humidity);
float Pressure = (bme.pressure / 100.0);
Blynk.virtualWrite(V3, Pressure);
float Altitude = (bme.readAltitude(SEALEVELPRESSURE_HPA));
Blynk.virtualWrite(V4, Altitude);
float Gas = (bme.gas_resistance / 1000.0);
Blynk.virtualWrite(V5, Gas);
if ((Gas > 0) && (Gas <= 50)) {
Blynk.virtualWrite(V6, "IAQ GOOD");
}
if ((Gas > 51) && (Gas <= 100)) {
Blynk.virtualWrite(V6, "IAQ Average");
}
if ((Gas > 101) && (Gas <= 150)) {
Blynk.virtualWrite(V6, "IAQ Little Bad");
}
if ((Gas > 151) && (Gas <= 200)) {
Blynk.virtualWrite(V6, "IAQ Bad");
}
if ((Gas > 201) && (Gas <= 300)) {
Blynk.virtualWrite(V6, "IAQ Worse");
}
if ((Gas > 301) && (Gas <= 500)) {
Blynk.virtualWrite(V6, "IAQ Very Bad");
}
}
void loop()
{
Blynk.run();
timer.run();
}
