It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot form a variable resistor, whose resistance varies depending on soil moisture. This variable resistor is connected in ...

"Arduino code to read and display humidity and temperature data using DHT11/DHT22 sensors." #include <DHT.h> #define DHTPIN A0 // Pin where the DHT11 is connected #define DHTTYPE DHT11 // DHT 11 ...

The soil moisture sensor module , built around the LM393 comparator, gives an active-low (L) level output when the soil is dry (determined by a pre-setted threshold value). This digital output (wet ...

The microcontroller is Arduino Uno. The FC28 Hygrometer and DHT11 sensors are used to measure soil moisture and temperature and humidity respectively. The sensors read the data and send it to the ...

Abstract: A low cost Arduino based Automatic Irrigation system using Soil moisture sensor is presented in this paper in which the soil moisture sensor gives it's output depending on the conditions of ...

void loop() { delay(2000); // Wait for 2 seconds between measurements float humidity = dht.readHumidity(); // Read humidity value from sensor float temperatureC = dht.readTemperature(); // Read ...
