How does washing machine sensing water level? The level sensor uses a pressure switch to detect the water level in the tub. This switch controls how high the tub fills with water. The big end of the hose connects to … Continue reading →

Do Smart light bulbs emit EMF radiation? Back in the day, when everyone was just using relatively safe incandescent light bulbs, things like “smart” light bulbs weren’t at all a concern. However, today, these WiFi-connected bulbs do pose a greater … Continue reading →

Technology. Water pressure sensors are transducers, generating an electrical signal in proportion to the pressure they measure. Water pressure sensors typically contain a physical diaphragm, often made of silicon, which bends as pressure is applied. How do water sensors work? … Continue reading →

In a dynamic water pattern, LiDAR can measure the water level with a measurement error of 9.8% at 200 cm and 4.3% at 150 cm. How is water level measured? Water Level Meter (or E-Line): A tape-like meter used to … Continue reading →

And certainly, the type of bulb you buy will determine heat issues. Incandescent lights are the hottest of the bunch. These can range from 50-250F starting with a 15 watt up to a 150 watt. The higher the wattage can … Continue reading →

Unlike incandescent light bulbs, LEDs don’t produce light using heat. This is part of what makes them so energy efficient. The downside is that their components can be sensitive to overheating, which can cause them to burn out prematurely. Why … Continue reading →

If this is a “12V” LED, which generally will consist of several LED chips in combination, no resistor is required. These are often supplied as replacements for automotive light bulbs such as the “festoon” type used as the interior light … Continue reading →

Theory (1) LED turn signal installation of the front or rear only while using bulb lights at the opposite end (front or rear) does not require flash controllers/resistors.Theory (3) A flash controller/resistor is necessary for every LED turn signal or … Continue reading →

Although Ashton’s was the first mention of the internet of things, the idea of connected devices has been around since the 1970s, under the monikers embedded internet and pervasive computing. The first internet appliance, for example, was a Coke machine … Continue reading →

One of the most common reasons a washing machine will fill with water when it’s turned off is due to a failed water inlet valve. This valve controls the flow of water into your washer that’s required for both the … Continue reading →

The pressure switch on a washing machine can be found at the top of the machine, and it identifies how much water is in the machine – telling the control board if the machine has been filled or emptied. How … Continue reading →

5 Common Uses Of Technology In The Classroom And One Challenge For Each Social Media And Digital Learning Tools. Reading Programs. Computer-Based Testing. Calculators, Smartboards, And Clickers. Learning Management Systems. What types of technology are used in the classroom? Types … Continue reading →

In addition to the chromaticity shift behavior from the LED packages, optical materials in the lamps and luminaires tend to yellow or discolor due to oxidation effects, leading to chromaticity shifts in the yellow direction. Do LED lights turn yellow … Continue reading →

The yellow color you see on bare LEDs are the color of phosphor, which is used to convert the blue light emitted from the chip into a wide spectrum, the visually white light. Different phospher recipe creates different quality of … Continue reading →

Optical level sensors are another option for applications that require a point level sensor. Optical switches work for either high, low, or intermediate level detection, and work well for practically any installation. Unlike float level sensors, there are no moving … Continue reading →
