Water level data detection is very commonly used in agriculture and the manufacturing industry. In this lesson, we’ll learn how to read the water sensor and transmit the data to a web browser.
OSOYOO Basic board x 1
OSOYOO ESP8266 Wi-Fi Shield x 1
Water detector sensor x 1
USB cable x 1
Jumper wires several
First, please insert the ESP8266 Wi-Fi Shield into your mainboard
And make sure the jumper cap is connected from E_TX to D4 and E_RX to D5. Connect the water sensor module to the mainboard as per the following diagram.
Unzip the file and double-click the wifi-lesson7.ino file.
Find the following lines:
char ssid[] = "******"; // your network SSID (name)
char pass[] = "******"; // your network password
Please replace the ****** with your correct Wi-Fi SSID and password. Otherwise,
your project cannot connect to the Internet.
Step E) After changing the above lines, load the sketch into the IDE.
Open your Serial Monitor, and you can see your router will assign an IP address to your IDE as follows:
In the above example, 192.168.1.81 is the IP address of my IDE. We need to set this IP address in our APP in the next step.
Step F) Open your OSOYOO IOT UDP Robot APP. If you haven’t installed this APP, please read the APP installation section in Lesson 2.
Step G) Make sure your cellphone is on the same local network as the Arduino. Open the APP, click Settings, enter your Arduino IP address from Step E and port 8888 in settings.
Now press any key on your APP, and your screen will display something like the following picture.
Connect the water sensor module to the mainboard as per the following diagram.
