Pin: Analog signal output, GND, VCCOperating voltage: 3.3- 5.5 VDC, Output voltage: 0-3 VDCInterface: PH2.54-3P, Size: 98 x 23mm (LxW)This capacitive soil moisture sensor distinguishes most of the resistive sensors on the market and uses capacitive sensing to detect soil moisture. It is made of corrosion resistant material which gives it an excellent service life.Built-in voltage regulator chip, support 3.3-5.5V DC, can be used for your Arduino and Raspberry Pi project. Applications: Garden plants ,Moisture detection ,Intelligent agriculture
I did see in some other peoples code that they only activated the sensor at a pre-set interval. I definitely want to implement that, plus I may as well start learning how to use the components efficiently. :P Luckily I did see that the dual-probe metal plated sensors were not good for the reason you stated. I went ahead and purchased a couple of the Capacitive Sensors (Link) . I used epoxy to seal the electronics and around the edge of the perf board to hopefully prevent water from entering the sensor. I have read still though that the constant usage will still eventually wear the sensor out. Thank you for sharing! I'm glad to see that there's quite a few of us working on this kind of project.
I'd say get an arduino and hook it up to a soil moisture meter and a water release valve, although it would be overly complicated lol https://www.amazon.com/dp/B07H3P1NRM/ref=cm_sw_r_cp_apa_i_acGUDbGR8XNPS
