LM393 Soil Moisture Sensor Module

This LM393 Soil Moisture Sensor Module is a versatile and reliable sensor that can use in a variety of applications such as Agriculture , Gardening & Science experiments.

This LM393 Soil hygrometers typically have two probes that are inserted into the soil. The probes are made of a conductive material, such as metal or carbon. As the soil dries out, the resistance of the probes increases. This change in resistance can measure by the Arduino and use to determine the moisture content of the soil.

LM393 Soil Moisture Sensor has two output modes: digital and analog. The digital output mode provides a high or low signal, depending on the moisture content of the soil. The analog output mode provides a voltage signal that is proportional to the moisture content of the soil. The sensor is powered by a 3.3V to 5V supply. It is compatible with a variety of microcontrollers, including Arduino.

The LM393 Soil Moisture Sensor works on the principle of resistance. The two probes that are inserted into the soil have a resistance that changes depending on the moisture content of the soil. When the soil is dry, the probes have a high resistance. As the soil becomes moist, the resistance of the probes decreases.

The LM393 comparator chip compares the resistance of the two probes to a reference voltage. The reference voltage is typically set to 2.5V. If the resistance of the probes is greater than the reference voltage, the output of the LM393 chip is high. If the resistance of the probes is less than the reference voltage, the output of the LM393 chip is low.

The output of the LM393 chip can use to determine the moisture content of the soil. A high output indicates that the soil is dry, while a low output indicates that the soil is moist.

LM393 Soil Moisture Sensor Pin Descriptions : –

The accuracy of the LM393 Soil Hygrometer Sensor is ±10%. This means that the sensor will be accurate to within 10% of the actual moisture content of the soil.

• VCC: The VCC pin is the power supply pin of the sensor. It should connect to a voltage source of 3.3V to 5V.
• GND: The GND pin is the ground pin of the sensor. It should connect to a common ground.
• DO: The DO pin is the digital output pin of the sensor. It provides a high or low signal, depending on the moisture content of the soil. A high signal indicates that the soil is dry, while a low signal indicates that the soil is moist.
• AO: The AO pin is the analog output pin of the sensor. It provides a voltage signal that is proportional to the moisture content of the soil. The voltage signal can read using an oscilloscope or multimeter.
• S: The S pin is the sensitivity pin of the sensor. It can use to adjust the sensitivity of the sensor. The sensitivity determines how much the output of the sensor changes as the moisture content of the soil changes.
