AGRO ELECTRONICS SYSTEM:

Appropriate environmental conditions are necessary for optimum plant growth, improved Crop yields, and efficient use of water and other resources. Automating the data acquisition process of the soil conditions and various climatic parameters lead to plant growth to collect information at high frequency with less labour requirements.

      In order to prevent dry running of motor and allow automatic restart of motor, sufficient water level is regained. Whenever water falls below LL level, micro-controller switches OFF the motor and sends SMS indicating dry running conditions. When the water rises beyond HL level, the micro-controller switches ON the motor again and sends sms indicating resumption of task. User need to go again and again and check the water level, he will get the alerts automatically whenever water is below the HL level.
       In order to ensure maximum reliability, one temperature sensor is mounted on body of motor to measure ambient temperature whenever temperature difference exceeds to specified safety limit, it sends the signal to switch OFF pump. We are using soil moisture sensor placed at the plants to know how much water content is present in the field
      Generally frequent power cuts and insufficient rains at various stages of growth are one of major causes of losses to farmers. Many farmers use induction motor pumps to irrigate their farms from wells. In this application, GSM modem receives any incoming text message directly and sends  any outgoing text message of micro-controller directly to designated cell phone number without being stored in control system cell phone memory.

Wireless Automatic Meter Reading System for Power Measurement, Load Control and Billing

Wireless Automatic Meter Reading System for Power Measurement, Load Control and Billing:   Introduction Due to use of  improper power management systems, the power requirement is increasing in the development of country’s economy. Over the past years, metering devices have improved a lot, and are expected to become even more advanced, offering more and more services. Meters in the past were electro-mechanical devices with poor accuracy and lack of ability. Recent developments in this direction seem to provide opportunities in implementing energy efficient metering  technologies that are more precise and accurate, error free, etc. The implementation of Wireless Automatic Meter Reading System(WAMRS) provides with many vital features as compared with the analogue utility meter reading with man power. Working of WAMRS: WAMRS provides a two way communication between the electricity company and the load by sending in a lot of power parameters and control s...

OTP AND BIOMETRIC TECHNOLOGY BASED LOCKER SYSTEMS

OTP AND BIO-METRIC TECHNOLOGY BASED LOCKER SYSTEM: INTRODUCTION OF PROJECT:        User home security is the prime concern for every user as it provides opportunities for them to work freely without worrying  about the home security. This OPT and Bio-metric Technology Based Locker System project provides a security system for the user’s house. For this, it takes the help of GSM Technology, each use will have a unique ID code for the user’s door. The security system will generate a unique encrypted code for user’s access and will SMS it to user with the help of GSM module, user needs to enter this code in order to open the door, otherwise the system denies the access and lock the door. Block Diagram: Description: Mobile Phone     In this project we have used one cell phone for user to send a unique code to his mobile. User’s  cell phone will use GSM Network for communication Microcontroller  Micro-c...
