ACEBOTT High Quality New 2.3cm*6.28cm Analog Output Signal Electronic Component Soil Moisture Humidity Sensor Module for Arduino
Product Description
Products Description
| Soil moisture sensor is a sensor used to detect soil moisture, which can sense the soil condition in time to make plants grow better. | |
| The soil moisture sensor is to insert two probes into the soil, and then as the current passes through the soil, the sensor obtains the resistance value by reading the current change between the two probes, and converts this resistance value to the moisture content. The higher the moisture (and the less resistance), the better the conductivity of the soil. Therefore, if the soil is short of water, the analog value output by the sensor will decrease; Otherwise, it will increase. | |
| Application: Smart agriculture, plant research and other scenarios that need to sense soil moisture. | |

Frequently Asked Questions
Q: What is the operating voltage range?
A: The sensor operates between 3.3V and 5V.
Q: What type of signal does it output?
A: It outputs an analog signal ranging from 0V to 2.3V.
Q: How does the sensor detect moisture?
A: It measures the resistance of the soil by passing a current between two probes.
Q: Can it be used with ESP32?
A: Yes, it is compatible with ESP32 using the provided pin configuration.
Q: What are the typical applications?
A: It is ideal for smart agriculture, gardening, and scientific plant research.
Q: Does the soil condition affect the output?
A: Yes, higher soil moisture results in lower resistance and higher analog
output values.
