Web Page Viewer

🔘Our new html page 📄viewer software called "WebPageViewer" was developed by us using the 'Visual Basic' programming language ( part of the MicroSoftⓇ Visual Studio Community 2022 edition development suite ), and has just been finished. Although it is basically a browser, its main purpose is to facilitate the design of html pages 🗐 for our µ-controller projects which have embedded web-servers,  such as the Green-House Gas Sensors 🏭( 01.12.24 )  and Solarometer 🌞( 13.10.24 ), and not for online browsing.
Application window after navigating to this blog
The main window has an uncluttered appearance, free from sidebars and bookmarks, to maximise space; menu bar and tool strip comprising address box and buttons 🔲at the top, page display area underneath and a progress bar in the status strip at the bottom. The width of the page display area defaults to be the same as the horizontal screen resolution ( 1080 px ) of the smart-phone 📱that will be used to display the page, making it quick and easy to see the effect of design changes when arranging the elements on a page in order to suit the phone screen size.

As is typical, version information 🛈, copyright © notice and a brief description of the application are contained in the 'About' window, which is a common feature of all our in-house 🏠software running on the WindowsⓇ OS. 🔳

Stand for the PMD - display version

🔘 Until now the atmospheric "Particulate Matter Detector ( PMD )" project based on a 🪴Plantower 🗼PMS5003 particle concentration sensor and having a ⎚ display had been assembled on a solder-less 🍞 breadboard, ( see 📅16 June 2024 ), while awaiting further development.

A 'U ' cross-section 🖼frame, which functions as a stand, has been designed and produced on a 3-D printer 🖶 so that the PMD ( comprising PMS5003, colour display & µ-controller ) is now self-contained and can be easily moved to different locations.

Being open construction the micro-usb connector for power and serial data, ( requiring the 'PMD_Serial'  software ), reset & boot buttons and SD card slot on the rear of the display are easily accessible. An SD card could perhaps be used to load an image when the PMD starts, or for data storage.
The stand is very stable. The addition of rubber feet provides extra non-slip adhesion on smooth surfaces, as well as protection from scratches. Overall dimensions are 122 x 70 x 64mm.
PMS5003 sensor is the blue module with fan air inlet.
