FDR Soil Sensors: Capacitive vs Resonant vs Swept Frequency Compared
If you are researching FDR soil moisture sensor technology, there are three distinct variants that are almost never properly compared, despite producing wildly different real world results. Budget basic capacitive FDR sensors are the most widely available low cost option, extremely popular for hobbyist and DIY projects. However they have one major well documented limitation: […]
