Soil moisture sensor

The soil moisture sensor is an essential tool for farmers, gardeners, and landscapers who need to monitor their plants’ water requirements. It works by measuring the electrical resistance between two electrodes in the sensor and converting it into a voltage signal that can be read by a microcontroller or other electronics.

The soil moisture sensor is easy to use and can be installed directly in the soil near the roots of the plants. It is compatible with a wide range of microcontrollers, making it ideal for use in various projects, such as automatic plant watering systems, smart irrigation systems, and soil moisture monitoring systems.

With the help of the soil moisture sensor, you can ensure that your plants receive the right amount of water, which can help them grow faster and healthier. Whether you’re a hobbyist or a professional, the soil moisture sensor is an excellent choice for anyone who needs to monitor soil moisture levels accurately and efficiently.

Description:

• This is a summary of the moisture sensor can be used to detect the moisture of the soil, when the soil is dry , the module outputs a high level , whereas the output low. Using this sensor make an automatic watering system , so that your garden plants need people to manage.
• Adjustable sensitivity ( shown in blue digital potentiometer adjustment ).
• Operating Voltage 3.3V-5V.
• Module Dual Output mode , a simple digital output , analog output more accurate.
• With fixed bolt hole for easy installation.
• Small PCB board size: 3cm * 1.6cm.
• Power indicator ( red ) and the digital switch output indicator ( green ).
• Using LM393 comparator chip, stable.
• VCC external 3.3V-5V
• GND GND External
• DO small board digital output interfaces ( 0 and 1 )
• AO small board analog output interface

Instructions:

• A soil moisture and humidity module most sensitive to the environment , usually used to detect soil moisture.
• Modules in the soil moisture reach the set threshold , DO port output high when soil moisture exceeds a set threshold, the module D0 output low.
• Digital outputs D0 small plates can be directly connected with the microcontroller through the microcontroller to detect high and low , thereby detecting soil moisture.
• Small plates digital output DO OUR relay module can directly drive the buzzer module , which can be composed of a soil moisture alarm equipment.
• Small plates AO analog output modules can be connected and AD through the AD converter , you can get a more accurate value of soil moisture.
