PIR

  Recently, development inquiries for passive-infrared(PIR) lenses continue. In general, PIR(Passive Infrared) lenses are arranged in a x b array with a number of Fresnel lenses. PIR(Passive InfraRed) lenses are usually not flat and are mostly round or square. In addition, separate materials should be used that can be passed on to the FIR(Far...

This is a brief conversation between and me and one of our customer. We have been tasked with developing a superior passive (pyroelectric) PIR-sensor-based motion detector for commercial and residential spaces to add to the customer's line of existing successful models.  The customer having little in-house optical expertise, they have an...

IR emitters were installed in a three-axis and hemispherical instrument for the PIR test to implement changes in radiation energy by distance of a person/PET. This enabled us to reduce and automate PIR performance measurements.  Hello, This is Fresnel Factory Co., Ltd. We introduce the 3 axis-hemispherical instrument for the...

  Fresnel Factory has supplied its customers with improved PIR lenses for human counter sensors. As a result, the customer's production process has been reduced. This has helped reduce labor costs, increase production yields, and reduce performance tolerance between customer’s products   The customer has already supplied the lens for PIR from...

We have developed a lens transmittance improvement for FIR sensor for absolute temperature measurement, and we introduce successful cases which increased about 10%. FIR (Far InfraRed) sensor is a sensor that detects the temperature by measuring the infrared (IR) emitted from an object and is used in infrared cameras.  <Lens transmittance...

Hello Guys, Today I introduce the product Eyecare Eyeview using FD08-10005 PIR Fresnel lens from Fresnel Factory. This product can make the kids kept away from TV. If your kids come to TV close, this product make TV shut down. It is very easy to install and use. PIR Fresnel lenses manufactured by Fresnel Factory can be used many kinds of...

Dear Sir/Madam Today I introduce POLY material DPP25 and DPE200 for PIR Fresnel Lens. DPP25(PP) is stronger to hot temperature than DPE200(HDPE). Obviously, DPE200 has cheaper price and higher transmittance rate than DPP25. DPP25 has a lower met flow rate than DPE200, so it takes more time to inject Fresnel lenses and therefore the price is...

Dear Sir/Madam, Today I introduce PIR Fresnel Lens which is used to Samsung SmartThings motion detector. Fresnel Factory have manufactured PIR Fresnel lenses to Samsung several years. And this lens is a new version modified with previous version. The product is the device belongs to SmartThings Home Automation System. It can detect if...

How are you? Today, we want to introduce you our mold core for PIR Fresnel lens which Fresnel Factory manufactures these days.  The mold of PIR Fresnel lens no. PD11-12010 is composed of 8 cores. General plastic injection can shoot 500,000 times for each core but the core for optical products shall be scrapped with 300,000 shots...

How are you? We are Fresnel Factory. With the expansion of Smart Home market, it is the increasing trend of inquiries about PIR Module. There are many inquiries not only about PIR lens and sensor but also about PCB design and housing, which indicates there are many companies undergoing difficulties  from them. So we checked how other companies...

From 2nd half of last year, many products related with smart home network and home security have been launched. Along with this phenomenon, Fresnel Factory has been very busy with the development of PIR Fresnel lenses indispensable for motion detecting sensors. The lens below is the lens we developed  to meet  the request from one of the big Korean...

Immedia Semi USA launched a new product applied motion detecting sensor lens cap which Fresnel Factory supplied. The product is called Blink, and the features of the product is as follows; Blink is a product streaming in a short time 5 ~10 seconds , which saves the screen as video clip, once the motion of a person is detected in front of...

Do you know what role do the pillar in the entrance to the escalator ? It is a device that adjusts the operation of the   escalator, sensing  people boarding and getting off. Previously, it was operated  when people pass the pillar placed between the entrance and exit . In this case it detected people passing...

" Detecting   was possible without lens. " " should I have unconditional cap?" Many people say and ask like this, so I will show you why you have to use fresnel lens for PIR(Sensor Cap) through a short movie. Not to mention that the modules in this movie are dealt with byDIYPRO, and sensors have high specifacation including...

    PIR sensor detecting angle 100-180 degree Our company is working on new project with PIR sensors for automation systems. Now we are developing PIR sensors and we need to find Fresnel lenses with the best parameters for our different products. I found at you company website wide variety of this kind of products and we are...

How are you,? This is Fresnel Factory. Today, we would like to introduce motion detecting devices which we saw in the CES Las Vegas in January. While in IFA, Berlin last year we saw main stream of motion detection devices with crude design not much different from the products in the past, in the CE Show this year, devices with design element...

My name is XXX.XXX , and I’m a head of Mechanical Design in XXXX XXX Security is a technological and market leader in the field of advanced security solutions for homes, offices and full-service central monitoring stations. The company enhances the business of remote monitoring stations by allowing them to offer superior security services to...

Recently, I received a email from a famous Turkey energy company. They are looking for PIR sensor for High-bay LED light for factory. Since there are none of sensor that meet 12m detection area and 15 diameter on the floor, they are request us to develop one. Detection area and angle of PIR sensor is mostly depended on sensor cab, which is...

This is a  domed PIR  lens , and we developed it for  request of local company . Sensing range 15 m, detection angle is 90 degrees above and below and 120 degrees right and left. 

We made a vedio to show you the difference between convex(or conversing) lens and concave(or diverging) lens. We shot the process. Experimental equipment Conversing Fresnel lens (DIYPRO product) Diverging Fresnel lens (DIYPRO product) Light Source using COB LED - Xicato The beam angle of Jigato module is 120 dgrees when nothing is applied....

It is the picture that shows you motion detection sensor applied LED lighting that was provided as samples to K Co. PIR sensor was originally used a lot for  on / off using the motion detecting from the past . The common example is a round device that is light on the front door . Looking  at the left in...

Used lens and sensor PIR sensor : Nicera RE200B Fresnel lens : DiYPRO PD05-12005 Usage : security motion camera This is motion sensitive camera develped from H Co., Ltd that occupies a unique position for water treatment. We used our proctuct PD05-12005 for the lens that is used in PIR. H Co., Ltd. tried testing many times...

These pictures show you what is a pplied PD175-36005 lens cap   for PIR sensors, and these  products seems to be HI-3009 or DK-011   made by D ogyeong in the market. Who  was a guard room where the door is an apartment , you 've mastered the introduction of the motion detection sensors to control...
