+
+## Description
+
+1515 stands for 15mm * 15mm on the cross-section. Not like most other companies,  M5Stack not just provide the highly productized learning board and programming platform, we also include the structural grade components to make a complete ecosystem for not only IoT development but IIoT (Industrial IoT) as well. 
+
+Aluminum profiles are most commonly used across industrial automation applications such as automated motion applications on process lines and industries throughout manufacturing. They are strong and yet light enough that they yet can be easily man-handled and built into various configurations as necessitated by the automation structure.  Outside of the traditional automation applications, structural grade aluminum extrusions are even being specified as part of weight reduction efforts.  extrusion aluminum sections are versatile and ideal for use in building automation applications, and aluminum is an excellent structural material which lends itself perfectly for use in profile extrusions. More likely than not, there is an aluminum profile that’s perfectly tailored to the specific automation application.
+
+As more advanced,  together with the  Aluminium-Profile accessories (connectors, slide-drops ...) and the Aluminium-Profile drilling machine which allows Pick-Cut-Drill,  you can even DIY your own framework. Furthermore, the add-on features of M5Stack system will bring your work into another level, you will benefit every step of the way in your IIoT project, all the way from structure prototyping, programming, network establishing, debugging, to the final productization.

+Let's break it down a little bit, start with the bottom part. 
+- The whole AC socket is consist of two parts. For people who are familiar with M5 industrial product series,  would recognize the base at the bottom is BASE26. we put a 3pin inlet socket at one customizable side of BASE26. This is where we power the AC socket from.

+## Description
+
+**M5SCALE DIY Kit** is a DIY kit of M5 that implements a digital scale, which makes it more of an Application-approach development kit. 
+
+The overall structure is made of acrylic material. The electronic part is the main controller, M5StickC and a  WEIGH unit.  
+
+A cantilever beam-sensor is used to detecting the bend over forced on top of the scale by object weight. 
+
+it will transfer the deformation into a voltage signal and as an input of WEIGH sensor which will be captured and read by M5stickC.
+
+Other than that, there also some small components that is included in the kit, you have the total freedom to assembly the whole thing and reprogram it as you like. 
+
+The software is open-sourced on GitHub, you can program it either with UIflow or Arduino. 
+
+The lego holes on bottom board allow you to place more M5 sensors for extension functions, Plus M5StickC is wifi available, you have the freedom to build something impressive.

+
+## Description
+
+**Base15** Base26 is a highly customizable bottom for industrial purpose. Similar to PLC Base but higher customized level. <br>  
+Package includes protoboard which allows you to add up your own circuit design.  On the board, two Grove bonding pads are reserved. Other components come with the package is an M type waterproof joint and a TTL-to_RS485 converter board. The M type waterproof joint (M12*15)can be assembled on the side and the bottom of the Base.
+
+'26' comes from the hight of the bottom which is 26 cm.  and each side on the Base is movable, cuttable and can be customized into different Interface.  With regards to the customization of the side, we have offered plenty of structural components alternative and it is totally opensource. You can 3D print the parts and replace the side as you like.<br>
+<img src="assets/img/product_pics/base/base26/base26_05.jpg" width="30%" height="30%">
+
+At the bottom side of the product, we have offered 2 different fitting ways:  Din-Rail,  Hunger. <br>

+
+Of course, it is absolutely compatible with the stackable M5module and extendable M5Units.
+This base gives you an unlimited of combinations, it is powerful, flexible, and covered with an industrial-grade case. If you happen to work in an industrial field, We especially recommend this Base to you which will surely give you the best and the fastest way to resolve your requirement..

+
+## Description
+
+**PM2.5** is a pollution sensor base with affordable price and high performance.  Integrated with PMSA003 and SHT20, makes it possible to measure the ambient quality of air, temperature, and humility all at one device. 
+
+Much discussion and research have taken place within academic and government environmental organizations as to how accurate such sensors are and whether they have a place in the enforcing of environmental regulation, or even providing an indication of air quality trends to citizens.
+
+With M5Stack product series, the system makes it much easier to deploy the measurement node all around the city and make it possible to build a complete ecosystem from regulation enforcement to citizen indication.
+
+With regards to PMSA003, it is a digital universal particulate concentration sensor designed by using the principle of laser scattering method. It is capable of continuous acquisition and computing the number of suspended particles in per unit volume which is also the particulate concentration distribution. Then turn it into mass concentration and output through digital GPIO.
+
+- Precise measurement implemented by laser scattering method.
+- Digital output, standard UART comunication
+- 0 error alarm rate
+- real-time response 
+- continuous acquisition
+- Minimum particle size resolution: 0.3 µm
+- Pattern structure design, 6-sides full dimension cover, high antijamming capability
+- Alternative in-outlet direction, wide application scale. users no need to redesign the air flue.
+- Tiny body, 12 mm. good for portable and wearable device
+
+SHT20 is a Humidity and temperature sensor IC.
+- Fully calibrated
+- Digital output, I2C interface
+- Low power consumption
+- The excellent long term stability
