WORKING

Welcome to the Arduino Based Project which consists of Touch Sensor. The basic functionality of sensor is that it detects near proximity (also known as touch) without depending on physical contact. In simple words, you can understand that its working is same as a simple switch or circuit. When any physical medium comes in contact with the touch surface. The internal circuit will be closed inside the sensor and current starts flowing. On the other hand, when this physical contact is broken or released, circuit will be opened. Here, we are controlling a fan using Relay and Touch Sensor. When we touch the Sensor, then the Fan turns on or else it stays off.

Obstacle Avoidance Sensor Module

• 3.3 to 5 V working DC voltage and I/O
• Working Current – ≥ 20mA
• 2-40cm Detection Range
• Effective angle: 35 ° with size: 28mm × 23mm
• Adjust multi-turn resistance
• Good for temperature within -10 ℃ – +50 ℃with output in TTL level

PIN DESCRIPTION

Obstacle Avoidance Sensor Module

IMPORTANT:

This sensor allows you to activate and deactivate the obstacle detection by manipulating the enable-pin.
It is activated by default which means that the sensor is in detection mode by default.
If you don’t want that, you need to remove the jumper with the label “EN” and put a control signal on the enable pin.

CIRCUIT CONNECTION

• An LED is attached to pin 13 of the Arduino Uno board to build a simple circuit of Obstacle Avoidance Sensor Module.
• With the LED attached to pin 13, connect pin OUT of Obstacle Avoidance Sensor to D8 of the Arduino Uno board for displaying the Output. The Output pin goes LOW, when obstacle is within range due to reduced resistance of the photodiode (component in Obstacle Avoidance Sensor).
• When the sensor detects an obstacle then the LED is turned ON automatically or else it stays off.
• The EN (Enable) pin is used to enable the circuit. The Pin EN is an activation sensor PIN (putting it in HIGH) and deactivating the sensor (putting it on LOW), but the result will be the same. When reading, the input is always 1. But is not used in the given circuit connection.

CODE

WORKING

This Arduino based Obstacle Avoidance Sensor mainly consists of an infrared-transmitter, an infrared-receiver and a potentiometer. In this particular sensor module, we identify the obstacle through the use of LED which is connected to Pin 13 of Arduino Uno board. Later, when the sensor detects an obstacle it turns ON the LED and further Output is being displayed on Serial Monitor.

Its working principle depends upon the reflecting character of an object. When the light emitted by the IR LED is incident on the photodiode after hitting an object, the resistance of the photodiode falls down from a huge value. One of the input of the op – amp is at threshold value set by the potentiometer. The other input to the op-amp is from the photodiode’s series resistor. When the incident radiation is more on the photodiode, the voltage drop across the series resistor will be high. In the IC, both the threshold voltage and the voltage across the series resistor are compared. If the voltage across the resistor series to photodiode is greater than that of the threshold voltage, the output of the IC Op – Amp is high. As the output of the IC is connected to an LED, it lightens up.

HC SR04 ULTRASONIC SENSOR

The Ultrasonic Sensor is used to measure the distance with high accuracy and stable readings. It can measure the distance from 2cm to 400cm or from 1 inch to 13 feet. It emits an ultrasound wave at the frequency of 40KHz in the air and if the object will come in its way then it will bounce back to the sensor. By using that time which it takes to strike the object and comes back, you can calculate the distance.

The ultrasonic sensor has four pins. Two are VCC and GND which will be connected to the 5V and the GND of the Arduino while the other two pins are Trig and Echo pins which will be connected to any digital pins of the Arduino. The trig pin will send the signal and the Echo pin will be used to receive the signal. To generate an ultrasound signal, you will have to make the Trig pin high for about 10us which will send an 8 cycle sonic burst at the speed of sound and after striking the object, it will be received by the Echo pin.

Further, check projects to properly understand the working of the Ultrasonic sensor and to measure the distance of any object using it.

• Static current: 2mA max
• Induction Angle: 15°

ESP8266 WIFI MODULE

ESP8266 is a Wi-Fi module that will give your project’s access to Wi-Fi or the internet. It is a very cheap device but it will make your projects very powerful. It can communicate with any microcontroller and make the project’s wireless. It is in the list of most leading devices in the IoT platform. It runs on 3.3V and if you will give it 5V then it will get damaged.

The ESP8266 has 8 pins; the VCC and CH-PD will be connected to the 3.3V to enable the wifi. The TX and RX pins will be responsible for the communication of ESP8266 with the Arduino. The RX pin works on 3.3V so you will have to make a voltage divider for it as we made in our project.

CIRCUIT CONNECTION

First of all we will connect the ESP8266 with the Arduino. ESP8266 runs on 3.3V and if you will give it 5V from the Arduino then it won’t work properly and it may get damaged. Connect the VCC and the CH_PD to the 3.3V pin of Arduino. The RX pin of ESP8266 works on 3.3V and it will not communicate with the Arduino when we will connect it directly to the Arduino. So, we will have to make a voltage divider for it. Three 1k resistors connected in series will do the work for us. Connect the RX to the pin 11 of the Arduino through the resistors as shown in the figure below and also the TX of the Arduino to the pin 10 of the Arduino.

Now it’s time to connect the HC-SR04 ultrasonic sensor with the Arduino. Connections of the ultrasonic sensor with the Arduino are very simple. Connect the VCC and the ground of the ultrasonic sensor to the 5V and the ground of the Arduino. Then connect the TRIG and ECHO pin of the ultrasonic sensor to the pin 8 and 9 of the Arduino respectively.

WORKING

After uploading the code, open the Serial Monitor and it will show you an IP address as shown below.

Type this IP address in your browser, it will show you the output as shown below. You will have to refresh the page again if you want to see again that the trash can is empty or not.

So this how this Garbage Monitoring System works, this project can be further enhanced by adding few more features in it like we can set one more message when the Trash Can is half-filled or we can trigger an Email/SMS to alert the user when Trash Basket is full.

In this IOT Project, an Ultrasonic Sensor is used for detecting whether the trash can is filled with garbage or not. Here Ultrasonic Sensor is installed at the top of Trash Can and will measure the distance of garbage from the top of the Trash can and we can set a threshold value according to the size of the trash can. If the distance will be less than this threshold value, means that the Trash can is full of garbage and we will print the message “Basket is Full” on the webpage and if the distance will be more than this threshold value, then we will print the message “Basket is Empty”. Here we have set the Threshold value of 5cm in the Program code. We will use the ESP8266 Wi-Fi module for connecting the Arduino to the webserver. Here we have used Localwebserver to demonstrate the working of this Garbage Monitoring System.

WORKING

Welcome to the Arduino Based Project which consists of 1602 LCD and Tilt switch module. The basic working of Tilt switch module is being described here. A Tilt Sensor switchis an electronic device that detects the orientation of an object and gives its output High or Low accordingly. Basically, it has a mercury ball inside it which moves and makes the circuit. So tilt sensor can turn on or off the circuit based on the orientation.

CASE 1: NOT TILTED

Initially, when it is in NOT tilted position as shown in the image below, it gives LOW output because of the liquid mercury complete the circuit by connecting the two electrodes. When the output is LOW on-board LED remain ON.

CASE 2: TILTED

When it is inclined in a particular direction or angle, the liquid mercury breaks the contact between the metal electrodes and the circuit gets open. Hence, we get HIGH output in this condition and the on board LED turns off.
