Soil pH is a measure of the acidity or alkalinity of the soil. The Ph is measured on a scale between 0 to 14. The Ph value lesser than 7 is considered acidic and greater than 7 is considered basic. If the pH scale is 7 then the material is neutral. The most ideal soil conditions for the growth & development of plants are neutral soil. However, some types of plants are still tolerant of soils with slightly acidic Ph.

This Soil PH sensor is high precision & portable Sensor that works with Modbus RS485.  All you need is to insert its probe in soil and get the reading using your MCU (Arduino, Tiva C, Raspberry, Personal computer).
