Is There Anything Important To Know Before Buying Light Switches?

The light switches are a part of every household and it would be best to choose the best switch depending on the style, ease of use, function and the proper safety standards are being followed. There is no one size fits all concept in switches so study which is suitable to the building.

Types of Light Switches

The following are the types of switches:

  • Toggle – it is a type of switch that is commonly seen in households, it has a lever that is moved up and down to turn the light on and off.
  • Push-button – a simple air or electric switch mechanism that turns the light on or off. The button is usually made of plastic or metal.
  • Rotary – operates by rotation and often has a clicking sound if it moves from one active position to another.
  • Rocker – it is spring-loaded that is connected to the switch that bears a resemblance to the toggle in terms of light operation. It is a flat surface and does not have a lever.
  • Automatic – this switch has a motion detector and is usually seen used in basements and cellars
  • Touch – to operate this switch, one must simply touch the surface, like a touch screen
  • Key lock – a specific key is entered into the switch lock to operate the light
  • Key card – it is usually seen in hotels, key card operate as a switch to the lights the moment the card is inserted into the slot available. It is a saving energy mechanism that prevents the lights being turned on when the room is unoccupied.
  • Pull – using a string or a chain, this switch usually operates a ceiling light
  • Remote controlled – as the name implies, the lights can be turned on or off using a remote.

Where to Place a Light Switch

The location of light switches when installing varies from each country because of regulation differences. There are countries that require a light switch to be placed with a height from the level of the floor. There is also times when there exists a minimum requirement on the number of switches to be put in terms of circulation spaces like corridors and staircases.

For wet spaces like the bathroom, follow the local regulations like the minimum distance from basins, toilets, and showers from the switch. And for outdoor installations, it is advisable to go for waterproof power outlets and switches.

Types Of HVAC Sensors

Nowadays, the earth suffers from the long-time problem of global warming. Global warming is the effect of trapped carbon dioxide and other types of pollutants that absorbs sunlight and radiation. Many people may not be aware of this, but humans are the major cause of why we experience global warming.

What Is A Transducer, and Where Are They Used In A Home?

Circuits and projects are built using electronic and electrical components. These components can be passive or active components like transducers, sensors, receivers, transmitters, and modules like Bluetooth, WiFi, RFID, GSM, GPS, and the like.  There are important processes performed by these circuits and projects; when they go smoothly, the desired result will be achieved. And one of those common processes is called transduction.

Transduction is a process involving the conversion of one form of energy to another. Note that there needs to be an element of sensing to determine the input energy and then using an element of transduction to convert it to another form.

In the day to day life of people especially in a household, transducers are everywhere. The common example is the microphone used in mobile phones, telephones. It can also be found in loudspeakers, thermometers, pressure sensors and antenna.

Definition of Transducers

A transducer is a device that electronically converts a form of energy to another. By energy, it can be electrical, mechanical, chemical, light, acoustic, thermal, electromagnetic energy, and other forms of energy.

In the example of the microphone in phones, the sound energy is converted into electrical signals. It will then be amplified into a certain preferred range. Once done, it shall then be converted to audio signals to be transmitted to the loudspeaker. Another example is the light bulb where electrical energy is changed into light energy.

Conditions of Transducers

The first condition of a transducer is the dynamic range which is the ratio found in the highest to the lowest amplitude to ensure the efficiency of the energy translation. The higher the range dynamically, the more precise and sensitive the conversion will be.

Repeatability as another condition is the capability of generating the same output every time a similar input is being stimulated. As for the noise of transducers, it can be electrical because of the presence of thermal energy within the circuits. Note also that small signals can be easily more corrupted by noise than larger ones.

Another property or condition of transducers is the hysteresis. To determine the output of transducers will not depend solely on the current input for it also considers the past input. Take an actuator as an example. It uses a gear train that poses some reaction that when its movement direction overturns, it will be resulting to a deceased zone just before the actual output overturns by a certain play within the gear’s teeth.

Does Your Home Have A Carbon Monoxide Sensor? Why Not?

Emissions from vehicles generally include carbon monoxide which is a silent but dangerous threat. Statistics say that more than 430 deaths are caused by this odorless, colorless but toxic gas each year. And it’s not just in your car or garage that you can be exposed to carbon monoxide. It can happen in your home, too.

Carbon monoxide gas is a molecule composed of one part oxygen and one part carbon. It results from carbon fuel such as gasoline, wood, coal, natural gas, propane and heating oil, fails to completely burn. If burned in an open area with a lot of ventilation, no threat should be expected. Unlike in confined spaces like kitchens, basements, or garages, carbon monoxide is definitely hazardous.

Carbon monoxide not only binds a person’s red blood cells, it also causes starvation of oxygen that will pass through the lungs.

Symptoms of Carbon Monoxide Poisoning

The following are the earliest signs that a person has been poisoned by carbon monoxide:

  • Nausea
  • Mild headaches
  • Lightheadedness
  • Frequent vomiting
  • Fatigue
  • Shortness of breath

Most symptoms are similar to those of the flu or cold, resulting to ignoring them easily. Unconsciousness and disorientation is a further symptom of poisoning.

To ensure a safer home, carbon monoxide must be easily detected. For convenience, it is recommended that a household have carbon monoxide sensor. These sensors are the best way to prevent poisoning. It works the same way as smoke or fire alarm by sounding a siren. It can also be connected to a home security system or through your smart phone. These detectors are easy to install, affordable and will likely save lives. It is recommended that each level of a house have a detector, near the bedroom and near the garage.

Tips to Prevent Carbon Monoxide Poisoning

Though carbon monoxide poses a serious risk, it is very preventable. Aside from being prepared with a carbon monoxide sensor, the following can also be followed for a safer home environment:

  • Do not use a gas range in heating the house.
  • Avoid running the car in the garage. It is more advisable to pull out the car from the garage first before warming it up.
  • Ensure proper ventilation. When gas-powered equipments like space heaters, generators and pressure washers are run in a closed area, carbon monoxide likely builds up faster. Places like the basement or the garage must then have proper ventilation too.
  • Practice safe cooking in a camp site. Always use a charcoal grill, camping stove or hibachi outdoors.

Why Are Power Supplies So Expensive To Replace?

It is noticeable that the prices and availability of various power supplies are having issues lately. Supplies with high capacities like 850W have becoming scarcer. A reason is partly because of crypto currency mining. Even suppliers that sell only a few quantities of PSUs have had their stocks sold out and their warehouses are left empty. Because the supplies are lowering while the demand is increasing, prices are automatically rising. So right now would not be the ideal time to have power supplies replaced.

List of Reasons of the Price Increase in PSUs

  • Higher demand – as everything else in economics, the higher the demand, the chances of prices increasing. The resurgence of crypto mining is one of the main reasons consumers are demanding more high capacity supplies.
  • Issues with sales chain – before a product goes to the hands of the consumer, it passes by a long chain starting with the factory to the brand’s headquarters, passing it to the local office, then to the distributors, resellers and finally to the consumers. Booking the orders for the supplies is done reversely. The resellers determine the demands of the consumers, and then make a booking to their distributors. The distributors will request an amount to the brand’s local offices then to the headquarters that will make the final order to the factories. This has been an inefficient practice being done. Though there are resellers large enough to go directly to the local offices or even to the headquarters. As these items get passed, so are their prices.
  • Currency exchange rates – parts are usually found in China as also the wages to the factory workers while the market is mostly centered on America. The exchange rate has been dropping since 2017. Because of this, factories are increasing prices to make up for the resulting losses due to the exchange rate.
  • Issues on the availability of electronic parts – the lead time for parts like coils, capacitors, MOSFETs, ICs, transformers has also increased. The price increase is not just because of the increase in demand but also because of the increase in production of products such as electric vehicles. The lead time takes up to 10 weeks at times.
  • Shipping costs – the shift to air cargo to transport the parts have resulted to faster deliveries and stock refills but costs much higher. With the increase in shipping costs, consumers are the ones who will carry that weight.
