  umbrella quality

  

  The quality of the ribs:

  

  determines the quality of an umbrella. The ribs are mainly divided into fiber ribs and steel ribs. Fiber rib umbrellas are more wind-resistant and rust-proof. The number of ribs is divided into 8 ribs, 10 ribs, 16 ribs, etc. The more the better.

  

  The density of the umbrella cloth:

  

  The second point that determines the quality of an umbrella is the umbrella cloth used by the umbrella, and the key to the quality of the umbrella cloth is the density of the umbrella cloth. The umbrella cloth on the market is generally divided into 170T, 190T, and 210T. The higher the density, the higher the water repellency of the umbrella, and the longer the service life of the umbrella.

  

  Straight-pole umbrellas are more durable:

  

  Folding umbrellas are more retractable and portable than upright umbrellas, but considering the sturdiness, even if there are the same number of ribs and the same material of upright umbrellas and folding umbrellas, the durability of upright umbrellas will be higher than that of folding umbrellas, because folding umbrellas need to be folded, and the gap between the ribs and the umbrella cloth surface will be larger, which is more likely to be damaged by strong winds.

  

  Turn the top of the umbrella to see the tightness:

  

  Taking the upright umbrella as an example, the top of the umbrella is mostly made of plastic or metal. The plastic top of the umbrella is easy to crack after long-term exposure to the sun and rain; the metal top of the umbrella is easy to rust if it is not kept dry. When purchasing, you can use your fingers to slightly turn it. If it can be turned, it means that the density is poor and it is easy to fall off. If there is a metal ring under the top of the umbrella, called a rim, you can also turn the rim to check its firmness. Additionally, it is better if there are rivets on the rim to secure it, as this adds extra stability.

  

  Turn the umbrella to test the handle:

  

  Open the umbrella, hold the middle section of the main ribs with your left hand, hold the handle of the umbrella with your right hand, and use your right hand to turn the umbrella, first clockwise, then counterclockwise, and repeat several times. In this way, you can know whether the handle and the ribs are firm.

  

  Folding and pulling trial:

  

  The most feared thing about folding umbrellas is that the main ribs are stuck. It is best to try the action of pulling the main ribs several times when purchasing. If it feels smooth when pulling, the quality of the umbrella is good. If it feels stuck, don¨t buy it.

Brief Introduction of PIR Sensor

  With the expanding influence of the industry, wired PIR motion sensor Our business is also constantly spreading, and the development of the market is also gradually advancing. https://www.sunlit-tech.com

  PIR sensor (Passive Infrared Sensor) is a passive infrared sensor. It is widely used in consumer products such as doorbells, cat eyes, induction switches, night lights, and security because of its low power consumption, low price, and simple use.

  

  

  (1) PIR detection principle

  

  PIR also has another alias, which is pyroelectric infrared sensor. Its detection principle is the pyroelectric effect, that is, the phenomenon that a substance will generate electric charge when the temperature changes. The normal human body temperature is 36-37 degrees, and the infrared radiation released is about 9-10um. The detection wavelength range of pir motion detector is generally in the range of 5-14um. That is, within the detection range of PIR, if there is an energy change of 5-14um wavelength, the PIR sensor will generate a current change, thereby giving a trigger signal. It should be noted here that PIR detects energy changes, not infrared radiation of a fixed wavelength. If an object with a fixed wavelength is not moving, PIR will not detect it.

  

  (2) Advantages of PIR

  

  Low power consumption, typical power consumption is about 10uA

  

  Low price, ranging from one or two yuan to five or six yuan

  

  Easy to use, the simplest one only needs to detect a pin level signal

  

  (3) PIR classification

  

  There are many types of PIR motion detector, which can be roughly divided into the following ways:

  

  Enablement controllable: switchable PIR

  

  Output signal type: digital PIR and analog PIR

  

  Is the sensitivity adjustable: adjustable PIR and non-adjustable PIR

  

  Sensitivity adjustment method: hardware adjustment and software programming adjustment PIR

  

  

  (4) PIR selection

  

  When selecting a PIR sensor, we generally need to consider the following basic requirements: voltage range, operating current, number of pins required, data output format, whether the sensitivity is adjustable, structural package size, and compatibility with the Fresnel lens. Another important consideration is cost. Without considering cost, it doesn¨t matter whether you choose a model or not. Just choose the best one. In actual product development, especially for consumer products, prices are very sensitive. Basically, all bosses want to use the cheapest device and debug it to achieve the best effect, especially for products with large shipments. If you don¨t have high requirements for product quality, it doesn¨t matter. If you have strict requirements for product quality and performance, you need to be very careful when selecting a model to avoid replacing the device when you find that it does not meet the requirements in the later stages of the project.
