Have you ever worried about your plant when you are away from them? afraid not as this project will make sure that your plant receives the necessary amount of water with a one-click of your phone.

Here's a list of component that you need :

ESP32

1CH Active H/L 5V OptoCoupler Relay Module

Micro Submersible Water Pump 3v-5v

Tube

4xAA Battery Holder C/W Cover

4xAA Battery

Jumper Wire


Source code :

#define BLYNK_PRINT Serial

#include <WiFi.h>

#include <WiFiClient.h>

#include <BlynkSimpleEsp32.h>

 

// You should get Auth Token in the Blynk App.

// Go to the Project Settings (nut icon).

char auth[] = "YourAuthToken";

 

// Your WiFi credentials.

// Set password to "" for open networks.

char ssid[] = "YourNetworkName";

char pass[] = "YourPassword";

 

#define WATER_PUMP 27

boolean state = false; 

 

void setup()

{

 // Debug console

 Serial.begin(9600);

 Blynk.begin(auth, ssid, pass);

 pinMode(WATER_PUMP, OUTPUT);

}

 

void loop()

{

 Blynk.run();

}

  

BLYNK_WRITE(V1)

{

 if (state == false) {

 state = true;

 Blynk.notify("You just watered your plant.");

 digitalWrite(WATER_PUMP,HIGH);

 delay(1000);

 }

 else {

 state = false;

 digitalWrite(WATER_PUMP,LOW);

 }

}

MOHAMMAD SAIFIQUL AIMAN B MOHAMMAD ALI 192011145 R2427-MICROELECTRONIC ENGINEERING A hall effect sensor is included in the ESP32. A hall effect sensor can detect magnetic field differences in its environment. The output voltage is proportional to the magnetic field strength. To operate as a switch, a hall effect sensor can be paired with a threshold detector. The majority of the time, Hall effect sensors are utilized to :  - Detect proximity;  - Calculate positioning;  - Count the number of revolutions of a wheel;  - Detect a door closing;  Here’s a list of parts you need to assemble the circuit  ESP32 DOIT DEVKIT V1 Board Read Hall Effect Sensor  Reading the hall effect sensor measurements with the ESP32 using the Arduino IDE is as simple as using the hallRead() function. In your Arduino IDE, go to File > Examples > ESP32 > HallSensor:  Copy the source code below Source code : // Simple sketch to access the internal hall effect detecto...

MOHAMMAD SAIFIQUL AIMAN B MOHAMMAD ALI 192011145 R2427-MICROELECTRONIC ENGINEERING There are ten capacitive touch GPIOs on the ESP32. These GPIOs can detect changes in anything that has an electrical charge, such as the skin. As a result, they may detect fluctuations caused by a finger touching the GPIOs. These pins may easily be incorporated into capacitive pads and can be used to replace mechanical buttons. Here’s a list of parts you need to assemble the circuit  ESP32 DOIT DEVKIT V1 Board  5mm LED  330 Ohm resistor  Breadboard  Jumper wires touchRead()  Reading the touch sensor is straightforward. In the Arduino IDE, you use the touchRead() function, that accepts as argument, the GPIO you want to read.  Assemble the circuit shown below Copy the source code below Source code : // set pin numbers const int touchPin = 4; const int ledPin = 16; // change with your threshold value const int threshold = 20; // variable for storing the touch pin value...
