Arduino Soil Moisture Sensor Circuit – Connection Diagram. Now that we have a complete understanding of how a Soil Moisture sensor works, we can connect all the required wires to the Arduino UNO board ...

The soil moisture sensor module , built around the LM393 comparator, gives an active-low (L) level output when the soil is dry (determined by a pre-setted threshold value). This digital output (wet ...

Soil Moisture Monitoring with Arduino – Circuit Diagram. Fig. 3 shows the physical connection of the system, while Fig. 4 provides the schematic. In both diagrams, the sensor’s output signal pin is ...

Combined1.ino is the code for all four sensors put together. The four sensors in the code by description are: //EC meter //pH sensor //DHT22 temperature sensor //Moisture Sensor. Currently I am having ...

This simple work will allow you to know how to read data from MEC-10 RS485 soil sensor using some development boards which are compatible with the Arduino IDE. This sensor is widely applicable for ...
