Gravity: Analog Spear Tip pH Sensor / Meter Kit Category_Radio & Wireless/GSM/GPRS Board Properties Controlled By WINThis Gravity: Analog Spear Tip pH Sensor Meter Kit can directly stab into semisolid material to measure the pH value. It can be used to measure the pH value of wet soil and various foods. The pH value of the soil is an important factor affecting the growth of plants. Suitable pH values for different plants differ from each other. The pH value of foods, such as fruit, meat, and vegetables are also an important indicator of their quality. For example,
