Garden Automation

8051/pic/avr/arm microcontroller,power supply,serial comm,ir,pir,ldr,moisture,fire sensor,lcd

The most important problems faced are the misusage of electricity and its wastage. Sometimes due to carelessness of the authorities and the workers lamps are left ON which results in wastage of electricity. Water wastage is another problem which needs to be dealt with. Our project helps to overcome all these problems. Firstly the Microcontroller around 4.00pm switches on the water supply once to water the entire garden few hours before opening of the garden for public. Next the gate is opened by running the motor which is driven by a motor driver operated by the Microcontroller. At around 6.00pm the lights are switched on depending upon the output of the LDR and the lights remain functional till the garden remains open for visitors. The garden remains open for about three hours and so around 8.50 pm a buzzer is sounded to indicate closure of the garden and alert the visitors. The gate is then closed at 9.00pm and one of the two lamps is switched off. One lamp is kept on throughout the night. In the morning the remaining lamp is switched off depending upon the signal sent by the LDR, light dependent resistor to the Microcontroller. These are the step involved in the operation of the circuit and the public garden automation. Microcontroller is used to supervise the actions of all other devices and to control the entire set of operations. View More

Designing an autonomous soil monitoring robot.

Through the monitoring of soil conditions land managers can respond rapidly to mitigate adverse events, such as extreme weather or ongoing drought. However, without an extensive system of sensors, gathering information over a large field takes an exorbitant amount of time. This mass collection of soil data would allow farm managers to study time-lapsed trends and variables within a particular region to provide quick assessment of land conditions. Currently, the client uses a bulky handheld wireless soil sensor to measure moisture content and temperature. To take measurements, the client must walk to the coordinates of interest, clear the ground of vegetation, manually insert the probe into the ground, and log the reading. The team is designing an autonomous soil monitoring rover to expedite data collection and reduce labor. The rover will be able to autonomously navigate through a field several acres in size and avoid obstacles. It will gather data on soil moisture and temperature at a set of given waypoints and relay the information back to the farm manager. Constructed with a custom welded steel frame, the first rover prototype will be a four-wheeled vehicle with front wheel drive. The vehicle will be equipped with a Stevens Hydra Probe II mounted to a linear actuator. Navigation will be handled using a GPS and wheel encoders. When completed, the rover will allow the land manager to analyze trends between soil data and pasture health, providing an accurate snapshot of a field. View More

Digital volt meter using aurdino

arduino microcontroller,power supply,serial comm,volt sensor,lcd

It's relatively simple to use an Arduino to measure voltages. The Arduino has several analog input pins that connect to an analog-to-digital converter (ADC) inside the Arduino. The Arduino ADC is a ten-bit converter, meaning that the output value will range from 0 to 1023. We will obtain this value by using the analogRead() function. If you know the reference voltage--in this case we will use 5 V--you can easily calculate the voltage present at the analog input. To display the measured voltage, we will use a liquid crystal display (LCD) that has two lines of 16 characters. LCDs are widely used to display data by devices such as calculators, microwave ovens, and many other electrical appliances. This project will also show you how to measure voltages above the reference voltage by using a voltage divider. View More

Motor Speed Control Use PWM

8051/pic /avr/microcontroller,power supply,serial comm,motor

Direct current (DC) motors have been used in variable speed drives for a long time. Pulse width modulation (PWM) is a method for binary signals generation, which has 2 signal periods (high and low). The width (W) of each pulse varies between 0 and the period (T). The main principle is control of power by varying the duty cycle. Here the conduction time to the load is controlled. View More
