Soil Hygrometer Detection Module Soil Moisture Sensor

Soil Hygrometer Detection Module Soil Moisture Sensor

Soil Hygrometer Detection Module Soil Moisture Sensor

Description

This is a simple moisture sensor that can be used to detect soil moisture.
When soil is dry then module output presents a high level, and low level when wet.
The sensor can be connected to an automatically watering device.
The sensitivity can be adjust by blue potentiometer
Working voltage : 3.3 V -- 5 V
Double output mode, the digital output is simple and give a more accurate analog output.
Board has a fixed bolt hole for convenient installation
Small board PCB size: 3 cm * 1.6 cm
Power indicator light (red) and digital switch output indicator light (green)
Comparator used is a LM393 chip for good stability.
Interface specification (4 wire):

VCC —— external 3.3 V to 5 V
GND —— external GND
DO —— small plate digital output interface (0 and 1)
AO —— small plate analog output interface
 

Instructions for use

1. Soil moisture module is most sensitive to the ambient humidity is generally used to detect the moisture content of the soil.

2. Module to reach the threshold value is set in the soil moisture, DO port  output high, when the the soil humidity exceeds a set threshold value, the module D0 output low

3. The digital output D0 can be connected directly to a microcontroller like a Raspberry Pi or Arduino to detect high and low values indicating detected soil moisture

4. The digital outputs DO can drive a relay module which can be used as a soil moisture alarm alert.

5. Analog output AO and AD module connected through the AD converter, you can get more precise values of soil moisture;
