🔘Our "Greenhouse Gas Monitoring System" measures the concentrations ( in parts per million, ppm ) of two potent greenhouse gases present in the atmosphere, Carbon Dioxide and Methane. The last upgrade added a webserver and embedded webpage ( 📅see 01.12.2024 ).
The upgrade described here has replaced the original AJAX/HTTP webserver with a 'Websockets' server also incorporating a redesigned webpage, having more features and an attractive appearance; ( image below, click to enlarge ).

The new features include displaying the WiFi signal level 📶to assist in choosing the location of the sensors, time-stamp provided by an NTP server, and a bar-chart 📊showing the recent history of the gas concentration measurements, updated in real-time every 🕞15 seconds.
Extensive use of graphics and images has contributed to the modern appearance of the new page design. The page's background image shows the outdoor unit which contains the two sensors; seen exposed to the atmosphere along the lower edge. The 'emojis' * which were included in the page design show some of the causes and consequences of these gases.🔘
NTP = Network Time Protocol.
* Emojis appear similar to images and icons but are characters from the UTF-8 character set.
