4 Best DIY Temperature Sensors Tutorials DIY Temperature Sensor This is a very simple DIY temperature sensor. You can use it to measure the temperature of your room, house, greenhouse etc. It is based on the LM35 series analog temperature sensor from Texas Instruments. The original version of this project was designed by David Johnson-Davies. This article shows how to build and program a slightly more advanced version of this circuit. The main difference is that the Arduino receives commands from the computer and returns values back to the computer. This allows us to monitor and record temperature changes in real time. Build Your Own Temperature Sensor Have you ever wanted to keep a close eye on the temperature of your home, or office? I recently found myself searching for a good solution to monitor my server room's temperature. It needed to not only have an easy way to access the data, but also be able to send me an alert if the temperature was outside of my specified range. The solution I came up with is a Raspberry Pi with a DHT22 sensor connected to it. The Pi is a small single-board computer that runs Linux. It has 40 GPIO pins to connect sensors and other devices, and it can run several different programming languages, such as Python and C++. One of the best parts about using a Pi is that it has built-in Wi-Fi and Ethernet capabilities, which allow you to easily access your project from anywhere! Thermistor Temperature Sensor Tutorial The thermistor is a type of resistor whose resistance is dependent on temperature, more so than in standard resistors. The word is a portmanteau of thermal and resistor. There are two main types of thermistors: Negative Temperature Coefficient (NTC) thermistors: The resistance decreases with increasing temperature. These are most often used as inrush current limiters, temperature sensors, self-resetting overcurrent protectors, and self-regulating heating elements. Positive Temperature Coefficient (PTC) thermistors: The resistance increases with increasing temperature. These are used mainly as resettable fuses and self-regulating heating elements. DIY Arduino Projects Arduino projects can be difficult to know where to start. The huge amount of variety on offer can be seriously intimidating. A good place to start is by getting an Arduino starter kit which contains all the pieces you need (minus any tools) for your first project. The great thing about Arduino, is once you've got the hang of it, you can use it over and over again for different projects. You don't have to buy a new board every time. You just need to change some components and reuse the same board. So how do you decide what project to try first? Well we've scoured the web and found our top ten best beginner Arduino projects that are perfect for self-starters, tinkerers and beginners alike.https://www.sinofudetec.com/gummy-machine/

Plastic Bottle Recycling in the News The plastic bottle recycling process is relatively simple, but requires a lot of resources. First, the bottles are cleaned of any loose material and then sorted by color. Next, the bottles are ground or chopped into flakes that can be melted. The flakes go through a washing process to remove any leftover contaminants and labels. Finally, the flakes are heated and formed into pellets that can be used to make new products. The best way to clean plastic bottles? Drinking from plastic water bottles is a lot of fun, especially when you're camping, hiking or otherwise enjoying the great outdoors. But the water bottles themselves can get a little grotty after a while. Depending on what's in them, the buildup can actually be dangerous to ingest. But how do you clean them? How do you prevent that buildup from coming back? And what about those weird stains? It's all easier than you think. Here are five easy steps to cleaning your plastic water bottle: Fill the bottle halfway with hot tap water and add two drops of dishwashing soap. Put the lid back on, and shake it vigorously for 30 seconds. Empty the soapy water out, and refill it with tap water. Swirl the water around to rinse off any remaining soap residue. Empty the rinsed bottle, and fill it with fresh tap water. Then, empty it again — no need to rinse! (You don't have to worry about residual soap getting into your next bottle of drinking water.) Repeat as necessary until you're done giggling at how much better your plastic bottle looks! New frontiers in recycling plastic bottles Plastic is one of the most common items found during beach clean-ups. But the material’s versatility and durability, which make it so popular, also make it difficult to recycle. In the process of recycling plastic, bottles are shredded into tiny pieces and melted down into pellets. These pellets can be made into a wide range of new products, such as outdoor furniture, playground equipment and flower pots. But this process has its limits – what can you do with broken fragments? Scientists from Texas A&M University have found an innovative new way to turn old plastic bottles into stronger building materials for roads – reducing waste and improving transport infrastructure at the same time. The Problem with Recycling Plastic Bottles You can't recycle yourself out of this mess. It's a myth that recycling plastic waste is a cure-all for our throwaway lifestyles, says Plastic Free. There are environmental and social problems with the way we consume plastic. Plastic is made from petroleum, natural gas and other carbon-based compounds. Manufacturing it uses large amounts of energy, creating air pollution and contributing to global warming. Plastic doesn't biodegrade and can take hundreds of years to break down. Most plastics are recyclable, but not all of them are economically feasible to recycle. Even if it can be recycled, the process uses energy and creates pollution. Recycling one ton of plastic saves 5,774 kilowatt hours of electricity — enough to power the average American home for six months — but also creates around 3 tons of carbon dioxide.https://en.wikipedia.org/wiki/Barrel

Everything you need to know about the camper rv solar panel？ The camper solar panel not only helps you to be in perfect harmony with the environment, but it will also solve any type of problem related to electricity. In an hour we used about 45 Amp hours (Ah), however, driving an hour, we only managed to recharge the battery by around 8 Ah. This situation forces, on many occasions, to have to condition our trip to find a campsite in which to spend the night. For this reason, the rv solar panels for campers has become an essential energy supplement that allows the auxiliary battery to be powered. In addition, by constantly recharging our battery without having to turn on the motorhome, it does not let it complete its cycle, thus extending its useful life. Before venturing into the installation of a camper solar panel, it is convenient to know what type is suitable for your motorhome, its price or how to install the camper solar panel, among other aspects. What type of solar panel is the right one for your motorhome? First of all, it is important that we know how to differentiate between solar thermal panels, whose collected solar energy allows us to heat water, and, on the other hand, photovoltaic solar panels that transform solar energy into electricity. Thus, photovoltaic solar panels are the ones that interest us the most. 1. Photovoltaic solar panels are divided into three categories: With monocrystalline silicon cells : These solar panels are better suited to the needs and characteristics of motorhomes, thus offering greater performance. In addition, they react to low insolation by producing energy even in winter. 2. With amorphous silicon cells : They are recognizable by their brown color and their performance is low, so they are not very adaptable to use in a motorhome. 3. With polycrystalline silicon cells : They are recognizable thanks to their blue color and their performance is low when the sun shines weakly. What power does it need to have? The power of the campervan solar panel that you should use will depend on the energy needs you have. To know it is as easy as making an inventory of the electronic devices that you have in your motorhome: Time of use, X power in Watt and adding all the electronic devices. To have more precision regarding the results, we recommend that you search the Internet for the information on each of them. In this way, you will be able to choose the camper solar panel for your installation based on your needs. However, we recommend that you choose a solar panel for your motorhome with a power greater than your results of your energy needs so that you do not have future problems. Advantages of having a solar panel There are numerous advantages in relation to the installation of a camper solar panel, which can be multiplied if what you want is to make your motorhome profitable. Also, if you rent your motorhome you can earn extra money that will add to the savings of all these expenses. First of all, solar panels have no impact on the environment and therefore do not generate waste or fuel. The camper solar panel adapts to any vehicle so you won't have to worry about which one to choose to best fit your motorhome. They also have a longevity of up to 20 years! For this, despite not needing any type of maintenance, it is important that you clean it from time to time in order to increase its performance. This makes it an economically profitable investment, in addition to the fact that its main objective is to save energy and, therefore, money. And, without a doubt, one of the main advantages is the independence that it will give you on your motorhome route since you do not have to worry about finding a place where you have to recharge the batteries. What more could you want? It is a wonder! https://www.renogy.com/solar-kits/rv-van-marine/
