DTMF CONTROLLED BOT DIY KIT

OVERVIEW:

The DIY KIT works on the concept of DTMF (dual tone multi frequency) tone command so received from any phone to remotely and control robot movement.

A cell phone is interfaced to a DTMF decoder in the system from its audio output socket for receiving tone commands. The receiving cell phone codes are converted into digital commands by using a DTMF Decoder which will identify the frequency of the key and convert that frequency to its equivalent digital code which is then fed to a microcontroller.

As per the commands sent from the sender’s mobile, the microcontroller will send signals the movement of the robot.

WORKING:

From the above block diagram,

Robot is controlled by a mobile phone which makes a call to the mobile phone attached to the robot. In the course of a call if any button is pressed a tone corresponding to the button presses is heard at the other end of the call. This tone is called DTMF tone. The robot receives this DTMF tone with help of a phone attached in robot. The processing of the tone is done by microcontroller with help of DTMF decoder. The decoder decodes the DTMF tone in to its corresponding binary digits and binary number is sent to the microcontroller. The microcontroller is programmed to take appropriate movement action for a given input. These decisions will be used to driver the motors forward, backward, left and right via l298 motor driver.

COMPONENTS REQUIRED:

• DTMF DECODER.
• BOT. 
• Jumper wires.
• 12 DC power supply

CLOUD STARTER KIT

OVERVIEW:

In Machine-to-Machine (M2M) applications, the ability to remotely monitor, collect, store and visualize data is paramount. Clients today have the choice to build out their own back-end server system and associated software elements, or look to a cloud-based system where much of the solution has been provided. Which solution is best depends on many factors including core competency, complexity, capital investment, time to market and more. 

Why choose a cloud based system?

Low start-up costs. No capital investment is required. There is no need to purchase hardware servers, software and licenses, and no need to build a secure location or computer room and manage the system. Cloud computing is described as a “pay as you go model,” meaning the system is always right-sized. You pay only for what you use. This is a critical point when first starting out, or for proof of concept. In a cloud solution, deploying a small number of devices for a proof of concept or demonstration does not require a capital expenditure of hardware and software. Also with a cloud solution, you can eliminate extensive software projects to write the data broker and other associated software elements when it is necessary to move data from the device to the servers and enterprise application.

The right cloud-based solution allows you to access any remote device, anywhere, anytime, from any device. Accessing your devices via desktop, someone else’s computer or a smartphone allows for device and location independence.

Automatic Meter Reading DIY KIT

OVERVIEW:

Automatic meter reading, or AMR, is the technology of automatically collecting consumption, diagnostic, and status data from energy metering devices (electric) and transferring that data to a central database for billing, troubleshooting, and analyzing. This technology mainly saves utility providers the expense of periodic trips to each physical location to read a meter. Another advantage is that billing can be based on near real-time consumption rather than on estimates based on past or predicted consumption. 

WORKING:

From the above block diagram, 

To achieve the instrument of data copying and transmission and other functions GPRS module is used. GPRS is networks for remote communication. They can combine with each other, through the net work’s gateway to achieve a user meter copying to control and transfer in distance.

Automatic Meter Reading system should have the following functions:

• Timing, location, automatically copies the user's Electricity volume.
• Low-power, low cost, reliable, safe.
• To realize the transmission and processing of data in distance.
• Through internet, updating meter readings and faults to real time data base.
• Later Data analysis is carried out to present billing information of individual meter reading systems. 
• Buzzer is turned ON to indicate “ Due bills ” 
• LCD is provided to display current meter readings and energy consumption.
• Also billing information will be sent through SMS as well. 

COMPONENTS REQUIRED:

• ATMEGA UNO 328.
• Two Relay shields
• GPRS Shield
• Jumper wires
• Screw shield.
• Buzzer
• LCD Shield.

ANDROID CONTROLLED BOT DIY KIT

OVERVIEW:

WORKING:

From the above block diagram,

Robot is controlled by a android mobile phone with remote control application installed. Initially both the Bluetooth devices should be paired.

If any button is pressed a byte corresponding to the button presses is heard at the other end of the Bluetooth receiver. The microcontroller is programmed to take appropriate movement action for a given input. These decisions will be used to driver the motors forward, backward, left and right via l298 motor driver.

• Jumper wires.
• 12 DC power supply.

Alcohol Detection Smart android DIY KIT

OVERVIEW:

In recent years, it has become a fantasy that the people put their lives in risk. More often, the people consume alcoholic drinks and drive the vehicles. There are more chances that the person can hit the vehicle to any obstacle approaching him in the opposite direction due to unconsciousness caused by drinking. Hence, we make a modest attempt to design and develop a simple, low cost alcohol detection android application using an independent microcontroller.
The main aim of this project is to design a system that can identify whether the person, driving the vehicle, is in complete conscious state or not. The designed and developed system is installed in the module confining microcontroller, alcohol sensor and Bluetooth module.

 

WORKING:

From the above block diagram,

If the driver is drunk, the alcohol sensor fixed to the microcontroller will identify the alcohol content and its output will be triggered. This output of the sensor will be sent as an input to the microcontroller. Thus, the microcontroller continuously sends real time sensed alcohol detected values to the Bluetooth application where police is using at the scene, now android application analyses the streaming sensor values and display the level of alcohol detected.

If the alcohol level is above the normal range then it displays the detected level along with corresponding violated due amount and also sends those information to the police data base and in turn violation due amount will be placed via SMS to the driver.

COMPONENTS REQUIRED:

• ATMEGA UNO 328.
• Bluetooth shield
• Alcohol sensor.
• Jumper wires
• Screw shield.
• Android application
