PM2.5 Test
PM2.5 is means less than equal to the diameter of the air 2.5 Micro-meteorary particles. ， Usually from industrial emissions. 、 Car tail. 、 Activities such as power generation 。PM2.5 Harmful to human health ， Long-term exposure causes respiratory disease 、 Cardiovascular diseases, etc. 。 And so... ， Conduct PM2.5 Test is It's very important. 。 Generally speaking ， There are several ways to do it. PM2.5 Test ： 1. Air quality monitoring stations ： Air quality monitoring stations will be established in major cities and environmental services ， Local access to data from monitoring stations PM2.5 Concentration 。 Citizens can use their cell phones. APP Or the official website, looking at real-time data. ， Timely information on air quality 。 2. Personal air quality monitor ： As technology develops ， There are also a few personal air quality monitors on the market today. ， It allows people to monitor air quality in real time, either at home or outside. ， Including PM2.5、PM10 Indicators 。 These instruments can connect to a cell phone or a computer. ， Synchronize display and storage of monitoring data 。 3. Professional testing institutions ： If more accurate data are needed ， You can choose to commission a professional environmental inspection agency. PM2.5 Test 。 These institutions usually have advanced equipment and specialized technicians. ， More accurate monitoring results could be provided 。 4. DIY Test Method ： Some. DIY It's... PM2.5 Test Method ， For example, using Laser Particle counter ， By measuring the amount of small particles suspended in air PM2.5 Concentration 。 This method requires a certain technical base and instruments. ， But it helps people to understand the air quality of the surrounding environment. 。 Overall ，PM2.5 Test is It's an important job. ， It helps people to keep abreast of air quality. ， Measures of protection 。 Through the above methods ， It can be done easily and quickly. PM2.5 Test ， Protecting the health of oneself and of the family 。 I hope people can focus on air quality. ， Efforts to build a cleaner and healthy living environment 。

ZTOF-4424-10A-Z45 Sensors Zgy-led
Dimensions: 4.4 mm × 2.4 mm × 1.0 mm Detection distance: 2cm~5m Detection Accuracy [Indoors]: ±3%
The ZTOF-4424-10A-Z45 is a highly integrated, compact single-point dTOF (direct Time of Flight) sensor. It integrates a VCSEL emitter, single-photon avalanche diode (SPAD) array, microlenses, TDC (Time Digital Converter), and MCU. dTOF technology and built-in sunlight-rejection and cover-contamination algorithms maintain measurement accuracy independently of target reflectance in varied environments, enabling precise ranging up to5m. The ZTOF-4424-10A-Z45 supports firmware updates through IIC, with modes and algorithms customizable to customer needs. An eye-safety control circuit meets Class I requirements. 1.Product Dimensions:the ZTOF-4424-10A-Z45 uses a12-pin LGA package measuring4.4mm (±0.05mm) x2.4mm (±0.05mm) x1.0mm (±0.075mm); unspecified tolerance is±0.05mm. 2.PCB Pad Dimensions:Figure11, PCB pads, top view. 3.Application Circuit:ZTOF-4424-10A-Z45 block diagram. Notes:1.The external AVDD capacitor should be as close as possible to the AVDDVCSEL and AVSSVCSEL pins. 2.HOST must always drive XSHUT; use a pull-up if host state is unknown. XSHUT requires HW standby mode without IIC communication. Soldering and Storage:1.Soldering Requirements:recommended reflow peak240ºC~260ºC, never exceeding260ºC. The source references a lead-free SMT profile and parameters:Figure13,recommended reflow profile;Table13,recommended oven-temperature test controls. Notes:1.Temperatures are measured at the package top. 2.Maximum reflow cycles:three. 2.Storage Instructions:ZTOF-4424-10A-Z45 is supplied in sealed moisture-barrier bags, with moisture sensitivity level3 (MSL3). Moisture absorbed during packaging can be released and evaporated during soldering, adversely affecting optical characteristics. Each device is baked before dry packing to minimize moisture. Sealed aluminized bags protect against ambient humidity during shipping and storage. Shelf Life:an unopened bag provides12 months from its marked date under the stated conditions:Shelf Life12 months;Ambient Temperature<40℃;Relative Humidity<90%. Beyond12 months, or if the humidity indicator shows excessive storage humidity, rebake the device. Floor Life:ZTOF-4424-10A-Z45 has MSL3 sensitivity, giving168 hours from bag opening under these conditions:Floor Life168 hours;Ambient Temperature<30℃;Relative Humidity<60%. Exceeding floor life or these conditions requires rebaking before reflow or dry packing. Baking:125±5℃ for8 hours;do not bake directly in carrier tape;avoid excessive vibration or impact that could seriously deform or damage packaging. IIC Communication:device address0x41, or0x82 when adding a1bit read/write bit to form8bit;maximum transfer speed1Mbits/s.
