Tencent Digital (Compilation: Guti) usually lives, what eggs, detergent, milk, and always meet the time to eat and forget to buy new goods. When this happens, either quickly go to the supermarket and buy it, or you have to choose to give it up. It's disappointing.
Now there is a BuyButtons smart button on Indiegogo that allows all of our items to be purchased to be added to the smart phone shopping list. In this way, when we go to the supermarket to purchase, we will not fall into one of two categories because we have to buy too many things.
BuyButtons are very simple to install and can be placed anywhere in the home, and can be customized to the name of the item to be purchased.
BuyButtons can be fastened to cabinet doors, refrigerators or even bathrooms, while waterproof and moisture-proof designs do not have to worry about being affected by water vapor.
The BuyButtons have a modular design. We can add as many buttons as we like, and make up any shape we like, without taking up space.
After you customize what you want to buy, just press the corresponding button, you can send data and code to the MasterHub storage center, and we can synchronize the code data from the MasterHub on the smart phone App, so we will not forget to buy Items.
The MasterHub home button can be connected to the home network via Wi-Fi, and then we enter the App, choose to add a new button, and then you can customize the addition of different labels, such as "bathroom", "kitchen" and "bedroom".
One of the services of BuyBottons on Indiegogo includes a text customization service. Different names can be printed using different etching techniques and can be directly attached to the buttons of BuyButtons.
If something like spices is accidentally broken, we can immediately press the corresponding button, and then it will be added to the list to be purchased in real time and automatically categorized into the "Kitchen" option.
How about, for the housewife and the home-runner, there is no longer a problem with BuyButtons that would waste more or forget to buy.

Fresnel Lens (Fresnel lens), also known as threaded lens, is mostly a sheet made of polyolefin material, but also made of glass. One side of the lens surface is smooth, and the other side is engraved with concentric circles from small to large. , Its texture is designed according to the interference of light and the requirements of relative sensitivity and receiving angle.
Fresnel lens is equivalent to infrared and visible light convex lens in many cases, the effect is better, but the cost is much lower than ordinary convex lens. It is mostly used in occasions where accuracy is not very high, such as slide projectors, film magnifiers, infrared detectors, etc.
The Fresnel lens has two functions: one is focusing, that is, the pyro-infrared signal is refracted (reflected) on the PIR, and the second is to divide the detection area into several bright and dark areas, so that it can enter the detection area A moving object can produce a changing pyro-infrared signal on the PIR in the form of a temperature change.
