Another possible cause of wrinkling or peeling of the PCB mask on a capacitive soil moisture sensor and its solutions:

Another possible cause of wrinkling or peeling of the PCB mask on a capacitive soil moisture sensor and its solutions:

After using this type of sensor for some time, there is a possibility that the PCB portion inserted into the soil may become damaged. Typically, the issue is the peeling or wrinkling of the PCB’s protective mask layer, which can impact the accuracy of the soil data intended for measurement. We generally believe that this […]

Automatic Garden Watering System – Controlling A Solenoid Valve with Arduino by A Plantmate Capacitive Soil Moisture Sensor

In this tutorial, we will show how to use an Arduino to DIY a Garden Automatic Watering System. We will be controlling a water solenoid valve with an Arduino, to turn the water valve ON/OFF by detecting the percentage of the soil moisture through the soil moisture sensor. Once the percentage of the soil moisture […]

Is it possible to extend the Plantmate Capacitive Soil Moisture Sensor cable to 33-feet(10 meters) long?

By design, the Plantmate Capacitive Soil Moisture Sensor cable is 85cm long with a micro USB adapter. Some DIY users may want to extend the cable to fit their own project. Is it possible to extend the cable to 33-feet? Let’s find out if it is possible. The cable that I am going to use […]
