Arduino Sensor System
Code
This is part of the code I used to program the sensor kit. The code labeled: dht_test-2 runs the humiture sensor and posts the output on the LCD screen.
Code
This is the second part of the code I used to program the sensors. This section tells the sensors how to respond when it detects rain.
Sensor System
This is the entirety of the sensor system.
Arduino Board
The circled item is the Arduino board itself. This board is programmed from the computer and allows the sensors to interpret the data they receive.
Breadboard
The breadboard, circled in this image, allows different sensors to connect to the same ports on the Arduino board. For example, the humiture and the raindrop sensors both needed to connect to the same ground outlet on the Arduino board and so they are connected on the upper right side of the breadboard.
Humiture Sensor
The sensor circled on the right side of this image is the humiture sensor. This sensor measures the temperature and humidity of the air. The output from this sensor is shown on the LCD screen in Celsius and percent humidity.
LCD Screen
The LCD screen shows the output from the humiture sensor.
Raindrop Sensor
This is the raindrop sensor when it is activated by water. The yellow light indicates that raindrops have been detected. When there is no rain, the yellow light will turn off.
