New Webpage for the Remote Soil Moisture Meter

🔘A "Remote Soil Moisture Meter - RSMM" has been in operation during the summer 😎 months since before this blog began; prior to  📅December 2021.

RSMM deployed in a herb garden - note LoRa antenna & solar panel

The RSMM transmits a soil moisture🚰 measurement every 🕥 hour using "LoRa" * wireless 🗼data technology to a receiver 📻module located conveniently indoors, about 35 metres away.

Several variants of the 📻receiver module were made; in general having either 🛜WiFi or Bluetooth functionality, in addition to LoRa. One of the 🛜WiFi options hosts a webserver, with embedded webpage to display the moisture 📏 measurement. This is accessed from a 📱smart-phone, 💻pc etc, having a browser installed. The original, basic, webpage design from 📅2021 is shown in the image below.

Version 1 webpage displayed on a phone

Recently the webpage has been given an upgrade to v2. The much improved webpage was designed using HTML, CSS & Javascript and has been considerably enhanced compared with v1 with several new features, such as 🛜WiFi signal level 📶indicator, chart 📈of moisture measurements over 🕥12 hours updated in real-time, and a button to pop-up moisture level definitions. The appearance has been revised and modernised with graphics, especially with the background image of the RSMM itself, a browser page tab favicon, and the use of different coloured panels to separate elements. Version 2 ( June 2025 ) is shown for comparison in the image below.

V2 will be uploaded to the receiver module next time the RSMM is deployed, and is operational.
