The calibration process involved comparing data from capacitive sensors with soil moisture content measured continuously by the volumetric water content (VWC) method. The results showed that sensor ...

Arduino UNO Wiring: soil sensor Analogue signal - > A0 // soil sensor power -> 5V // LCD VCC -> 3.3V // LCD SDA -> A4 // LCD SCL -> A5 // TEMP power -> 13 // temp Analogue signal -> A1 soil Sensor is ...

The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...

Capacitive Soil Moisture Sensor This is a capacitive soil moisture sensor which runs with a standalone ATmega328P and utilizes the MySensors framework. It can however be adapted to any other framework ...

Like this low-power soil sensor project and the custom controller for six soil sensors, [rbaron’s] w-parasite uses a “parasitic capacitive” moisture sensor to determine if it’s time to ...

I'd probably use one module to run 5 or 6 sensors, conformal coated and buried. I'll do some shallow trenching for wires, and mark the sensor locations somehow so I don't mow over them.

As a bonus, we also give you the ambient temperature from the internal temperature sensor on the microcontroller, it’s not high precision, maybe good to + or – 2 degrees Celsius.” ...

For now, just moisture. However, there's no reason I can't add more sensors if I want to. pH isn't something that's going to be changing rapidly. I can check that annually and probably be fine.
