Introduction: Digital Humidity and Temperature Monitor
Hi every one
Ensuring proper indoor humidity has important skin, allergen and other health benefits by inhibiting the growth of , bacteria, viruses, fungi, and etc . This Digital Temperature and Humidity Monitor allows you to check comfort conditions at a glance with this indoor humidity gauge and thermometer (temperature ) combination. It's more than accurate, above all every one can make it , let me demonstrate you how i did :))
Application Temperature & Humidity Monitor
Indoor humidity sensor (%RH)
Indoor temperature sensor (degrees Fahrenheit and Celsius)
Humidity Temperature and Dew Point (dew point temperature or dew point is the temperature at which dew forms and is a measure of atmospheric moisture )
Step 1: Electronic Components
you need this project
1- Arduino ( any arduino types )
2-DHT11 &22 (humidity and temperature sensor )
3-jumper wires (3pc )
4-Breadboard (optional )
5-Arduino usb cable
6- Arduino IDE
Step 2: Circuit Schematic
DHT Vcc pin to 5v pin in arduino
DHT GRN pin to pin GRN pin in arduino
DHT out pin to pin 7 in arduino
Step 3: Code
#include
dht DHT;
#define DHT11_PIN 7
void setup()
{
Serial.begin(115200);
}
void loop()
{
int chk = DHT.read11(DHT11_PIN);
Serial.print("Temperature = ");
Serial.print(DHT.temperature);
Serial.print("*C"); Serial.println();
Serial.print("Humidity = ");
Serial.print(DHT.humidity);
Serial.print("%"); Serial.println();
double gamma = log(DHT.humidity / 100) + ((17.62 * DHT.temperature) / (243.5 + DHT.temperature));
double dp = 243.5 * gamma / (17.62 - gamma);
Serial.print("Dew point = ");
Serial.print(dp);
Serial.print(" *Celcius ");
Serial.println();
delay(3000);
}
//
you need DHT library as well here below you can download
//
Step 4: RESULT
you did it !!!!! one more step , uploading code and running it, then click Serial Monitor or you can (Tools -> Serial Monitor or Ctrl + Shift + M) sensor data will appear
serial monitor will shown u date . I hope you enjoyed this project and if there is something wrong or not clear please let me know.follow me for many more projects to come
Thanks for reading .
