Soil Moisture Meter - real time data

I am posting here moisture readings in real-time using two of the widgets in my ThingSpeak channel; see 24 July. If the sensor, LoRa link and WiFi are all operational, an update is made automatically every hour when a moisture measurement is taken in the herb garden. Other changes I have implemented are two additional widgets in ThingSpeak to display LoRa link received signal level, and receiver module chip temperature. Also I have removed the previous dependency on Node-Red by modifying the firmware so that the receiver module sends measurement data directly to ThingSpeak. ThingSpeak Embedded Plot
