  • 【Updated Version】- This capacitive soil moisture sensor is different from most of the resistive sensors on the market. It uses the capacitive sensing principle to detect soil moisture, avoiding the problem that resistive sensors are easily corroded, and greatly extending its working life
  • 【Wide Voltage】- The sensor has a built-in voltage regulator chip that supports a wide voltage range of 3.3~5.5V, which means it can work properly even on a 3.3V Arduino main control board
  • 【Note】- Micro PCs such as Raspberry Pi only need an external ADC (analog signal to digital signal) conversion module to work
  • 【Parameters】- Working voltage: 3.3 ~ 5.5 VDC; Output voltage: 0 ~ 3.0 VDC; When humidity is high, the voltage is low, and when humidity is low, the voltage is high. Please go back and measure with a multimeter to confirm. Interface: PH2.54-3P
  • 【Packing List】- Included 6 x Updated Capacitive Soil Moisture Sensor(98 x 23mm (LxW) / 3.86*0.91inch

These tested very well for me, and I'm looking forward to using these to enhance my wife's gardening efforts. Quality seems very nice; well-constructed, and I think I'll be able to 3D-print some caps that will fit these to help make these more invisible in the plant pots. Obviously these kinds of boards will corrode and decay over time as they're exposed to more and more water and/or weather, so I don't yet know how well these handle any of that. But, at barely over a buck apiece, the value here, imo, is quite good, they're easily replaceable, and I'd recommend these.
