Overview of this Soil Moisture Sensor Module
Introducing roboway Soil Moisture Sensor Module at the best price in India with Roboway. This sensor module  used for measure soil moisture level and it helps check if the soil is dry or wet and perfect for plant care. It is mostly use for automatic plant watering systems and it can turn on a pump or alert when soil is dry. Module  works on low voltage (3.3V–5V).
This module gives both analog and digital output there is analog output shows moisture level and digital output can be set with a threshold. It is used in greenhouses, indoor gardens, and smart farming. It is easy to place directly into soil or pots and it can can turn on a pump or alert when soil is dry.
Features
Detects soil moisture level – It tells whether soil is dry or wet.
Supports both analog and digital output – easy to use with different microcontrollers.
Operates on 3.3V to 5V – This module suitable for Arduino, Raspberry Pi, and other boards.
Built-in LM393 comparator chip – Sensor gives stable and accurate digital output.
Reusable sensor – It can be used in multiple projects or experiments.
LED indicators – It can shows power status and moisture detection.
Specification
Operating Voltage: 3.3V to 5V
Output Mode: Dual output – Analog (AO) and Digital (DO)
Analog Output Accuracy: High accuracy for precise soil moisture reading
Installation: Comes with fixed bolt holes for easy mounting
Comparator Chip: Built-in LM393 comparator for digital signal processing
Panel PCB Dimension: Approx. 3cm x 1.5cm
Soil Probe Dimension: Approx. 6cm x 3cm
Cable Length: Approx. 21cm for flexible placement
SKU: RW-062
Connections:-
- VCCÂ connect to 3.3V-5V
- GNDÂ connect to GND
- DO  digital value output connector(0 or 1)
- AOÂ analog value output connector
Usage:-
- Soil moisture module is most sensitive to the ambient, generally used to detect the moisture content of the soil.
- When the module can not reach the threshold value, DO port output high, when the the soil humidity exceeds a set threshold value, the module D0 output low;
- The small board digital output D0 can be connected directly to the MCU, MCU to detect high and low, to detect soil moisture;
- Small board digital output DO can directly drive the buzzer module or relay module in our store, which can form a soil moisture alarm equipment;
- Small board analog output AO and AD module connected through the AD converter, you can get more precise values ​​of soil moisture;
