Gravity: Analog Spear Tip pH Sensor/Meter Kit - analog pH meter

Description

Set with a measuring module and a probe for measuring the pH of wet soil and food products. The probe has a sharp end made of stainless steel, so it can be easily inserted into a semi-solid material.

Soil pH is an important factor influencing plant growth. The respective pH values for different plants differ from one another. The pH of foods such as fruit, meat and vegetables is also an important indicator of their quality. For example, by measuring the pH value of meat, we can determine whether the meat we buy is fresh or not.

The module is powered with the voltage of 5 V and has an analog output with a voltage range from 0 to 4 V. Thanks to the BNC connector of the probe and the Gravity connector, the set can be easily connected to the microcontroller and quickly set up a measuring station. The user manual and sample programs are available on the Wiki page.
