Next we connected the water flow sensor’s output to the Arduino board (filled with the sketch) and allowed water flow through the water flow sensor at a steady rate of about 1 Litre/minute. Besides ...

WIFI_SSID - WIFI network name for your wireless network.. WIFI_PASSWORD - Wireless Password. MQTT_PUBLISH_TOPIC - MQTT Topic Name, VERY important you name this per device. I'd suggest using this to ...

Working of the Arduino Water Level Sensor with 3 LEDs as Output. Now let us move to the real-world working demonstration of 3 LED Output Water Level Indication Project. Here instead of a single LED, 3 ...

The complete water flow sensor Arduino code is given at the bottom of the page. The explanation of the code is as follows. We are using the header file of the LCD, which eases our interfacing the LCD ...

Here is a tested Arduino project that uses 3 sensor probes as water level indicator with 3 leds and one LCD display + a simple controller that turns on a motor when the water has reached the desired ...

If the water is somewhat low, the Arduino-controlled relay powering the tree is switched off and then on again, every 5 seconds. If the base is nearly dry, the tree asks for water by blinking the ...

The Arduino sketch monitors the water sensor. After detecting water for 30 seconds continuously, it encrypts the message payload and sends to the NodeJS proxy. The proxy decrypts the JSON payload and ...
