Description

This is Arduino project water level indicator using Arduino Nano and ultrasonic sensor for you in this time. Accordingly Circuitstoday site describe that Wireless Water Level Indicator Using Ultrasonic sensor & Arduino is an amazing and very useful project. The objective of this project is to notify the user the amount of water that is present in the overhead water tank. This project can be further enhanced to control the water level in the tank by turning it ON, when the water level is LOW, and turning it OFF when the water level is HIGH. Thus, the Arduino water level indicator helps in preventing wastage of water in overhead tank. This project is wireless so, it is easy to install and it can work up to 100 meters.

In this project two circuits are used: a transmitter circuit and a receiver circuit. The transmitter circuit makes use of an ultrasonic sensor to measure the water level in terms of distance. This data is sent to the receiver circuit using RF communication. The water level is shown in terms of percentage on a 16×2 LCD module, which is connected to receiver circuit. Read more Here.

One of the largest solar power projects in Massachusetts is being constructed on the property of a former coal-burning power plant in Holyoke. 

More than 17,000 solar panels are being installed in the shadow of the smokestack of the former Mount Tom Power Station. The nearly 6 megawatt solar farm should come online in January.  The old power plant, which operated from 1960-2014, and the smokestack – a landmark for people traveling up and down I-91 -- will be demolished in the spring.

The solar panels are being installed on 22 acres of the 128-acre Mt. Tom Power Station property along the Connecticut River. At a ceremonial groundbreaking Thursday, ENGIE North America President and CEO Frank Demaille said the project is a “landmark” for the international company as it transitions from large centralized power plants to local low-carbon emission energy production.

Holyoke Gas & Electric has signed an agreement to purchase all the electricity produced at the solar farm. It is enough to power 1,000 homes.  James Lavelle, the manager of the municipal power company, said the terms of the agreement will help to maintain some of the lowest electric rates in the region.

To use the on-chip oscillator, an 11.0592 MHz quartz crystal is connected to pins 18 (XTAL2) and 19 (XTAL1) of the microcontroller. Two 33pF ceramic capacitors are connected from the crystal to ground.

The reset on the 8051 microcontroller is active high i.e. upon applying a high pulse to RST pin, the microcontroller will reset. A 10KΩ resistor is connected from the RST (Pin 9) of the microcontroller to ground.

A 10µF electrolytic capacitor is connected between the positive supply and RST pin. A push button is connected across the capacitor.

The External Access pin (Pin 31) is connected to positive supply using a 10KΩ resistor. This completes the basic connections with respect to microcontroller. For more information about this microcontroller project RFID based attendance system using 8051 you can read more HERE.

Construction under way for 8,000-plus-panel solar project by Marcus Wolf

Robometricschool. - This is one information for you about the solar power with the title Construction under way for 8,000-plus-panel solar project that written by Marcus Wolfand and published in Watertown Daily Times site.

Construction is underway for a Colorado-based energy company’s more than 8,000-panel solar array on 10 acres on County Route 67.

Tony Alvarez, a superintendent with the manufacturing and installation company TerraSmart, said his crew has been installing the wracking that will hold 8,680 ground-mounted photovoltaic solar panels for about a month. The Florida-based installation company expects its workers to finish installing the wracking and the panels for the 2,000-kilowatt project, named Brookside Solar, within the next couple of weeks, Mr. Alvarez said.
“The only times we stop is thunderstorms or lightning,” Mr. Alvarez said. “It’s coming along.”

Brookside Solar, owned by AES Distributed Energy, Boulder, Colo., will be built on about 10 acres of a 221.7-acre property owned by Teddy A. Sutton and Lorraine LeRoux at 24805 County Route 67.

Kaleigh T. Pitcheralle, construction manager for M+W Group, which oversees the construction and installation of Brookside Solar, said she expects construction to conclude by November, adding that many of the ground components have already been installed, including the central inverters and conduits. New utility poles had to be installed for the solar project to interconnect to National Grid’s power grid, and Ms. Pitcheralle said workers also needed to build a gravel road to access the property.

“All of our underground is complete,” she said, adding that they are waiting for combiner boxes.

Michael J. Brennan, a project manager with M+W Group, said the array will send the energy through wires connected to the panels as direct current electricity to the two central inverters, which will then convert the electricity to an alternating current.

Description

Accordingly Electronicshub site that published this circuit describe that RFID based attendance system has very simple circuit design. The RFID Reader has transmit and receive pins. These pins are connected to the transmit and receive pins of the micro controller i.e. PD0 and PD1 pins of microcontroller.VCC is connected to 5v and GND is connected to ground.

If pins are not available to the module, connect it using DB9 connector. PD0 pin is receiver and PD1 pin is transmitter.

RFID module communicates with the controller using USART, where USART is a communication protocol. USART is acronym for Universal Synchronous and Asynchronous Receive and Transmit.

Serial data can be transmitted from RFID module to microcontroller using UART. ATmega8 microcontroller has USART registers internally. One should declare these registers in order to transmit or receive data serially.

A four-passenger, solar-powered car named "Violet" is driving thousands of miles across Australia. But that trip is just the precursor to a harrowing race that spans the punishing landscape of the country's outback and is open only to vehicles powered by the sun.

The car, which was designed and built by engineering students from the University of New South Wales (UNSW), departed Sydney, Australia, on Sept. 20 and will travel about 2,700 miles (4,300 kilometers) to Darwin, on the continent's northern coast. This scenic route allows the team to test the car, and serves as a regional outreach tour, introducing their fellow highway drivers to the car's futuristic design.

Then, on Oct. 8, Violet will take part in the 30th Bridgestone World Solar Challenge, competing against 47 teams representing 21 nations.

The race will take them from Darwin in the Northern Territories to Adelaide in South Australia, covering 1,877 miles (3,021 km). Though the event is scheduled to last from Oct. 8 to Oct. 15, the winner is expected to cross the finish line in Adelaide's Victoria Square in the early hours of Oct. 12, officials with the World Solar Challenge announced in a statement.

UK makes solar power leap with first subsidy-free farm by DW made for minds

Robometricschool. - This is one information for you about the solar power with the title UK makes solar power leap with first subsidy-free farm that published in DW made for minds site.

This summer was the "cleanest ever" in terms of the UK's energy consumption. That's more good news for British supporters of renewable energy on the day the country's first subsidy-free solar farm opens.

The UK's first solar power farm to operate without government subsidies opens on Tuesday, in a further indication of how the country's energy market is moving towards renewable sources.

The 10 megawatt (MW) solar farm — which can generate enough electricity to power around 2,500 homes — has been developed in Bedfordshire, about 40 miles north of London, by Anesco, a private company that specializes in developing solar and battery storage sites before selling them on. The farm's significance lies in the fact that it is the first to be developed in the UK that is not reliant on government funding or incentive schemes.

Solar power still accounts for a relatively small amount of the UK's energy consumption (3.4 percent in 2016) but it is growing rapidly in importance, along with other forms of renewables such as wind, hydroelectric and bio energy.


The most recent UK figures showed that renewables' share of electricity generation was just under 27 percent in the first quarter of 2017 with the use of solar power growing by 16 percent in that period as a result of increased capacity.
