## Overview

The OVJ Soil Moisture Sensor is a cutting-edge tool designed for precise soil moisture monitoring. Featuring a nickel-plated surface for durability, it operates on a voltage range of 3.3V-5V and utilizes an LM393 comparator chip for stable performance. Its widened sensing area allows for comprehensive moisture control, making it an essential device for both amateur and professional gardeners.

## Description

Product introduction: 1.Use the soil sensor made by our company to test the soil moisture, the surface is treated with nickel plating, with a widened sensing area, which can improve the conductivity, prevent the problem of easy to touch the soil and prolong the service life;2.The product can control the humidity of the soil in a wide range and adjust and control the corresponding threshold value through the potentiometer. When the humidity is lower than the set value, the DO output is high level. When the humidity is higher than the set value, the DO output is low level.3.Comparator using LM393 chip, stable work. Operating voltage 3.3V-5V. Fixing bolt holes for easy installation. PCB size: 3.2cm * 1.4mWiring instructions (4-wire system):1 VCC external 3.3V-5V2 GND External GND3 DO small board digital output interface (0 and 1)4 AO small voltage analog outputModule instructions: 1. The sensor is suitable for soil moisture detection;2.Blue potentiometer module is used for soil moisture threshold adjustment, clockwise adjustment, control the humidity will be greater, counterclockwise smaller;3.Digital output D0 can be connected directly with the microcontroller, high and low level through the microcontroller to detect soil moisture;4.small board analog output AO can be connected with the AD module, through AD conversion, you can get a more accurate value of soil moisture;
