SOIL MOISTURE SENSOR

SEN-Moisture

1. GENERAL INFORMATION

Dear costumer,

thank you very much for choosing our product.
In following, we will introduce you to what to observe while starting up

and using this product.
Should you encounter any unexpected problems during use, please do

not hesitate to contact us.

With its two long sensors, the soil moisture sensor oers an optimum re­sult and is ideally suited for e.g. an automatic irrigation system.
The soil moisture sensor is easy to operate. The two large exposed pads

act as probes for the sensor and serve as a positioning resistor. The more

water there is in the ground, the better the conductivity between the
pads, resulting in lower resistance and higher output voltage.

Please note that if the sensor is in damp soil for a longer pe­riod of time, the contacts may corrode.

2. COMMISSIONING WITH THE RASPBERRY PI

Raspberry Pi Moisture ADC

GND (Pin 6, 14) GND (Pin 1) GND

3v3 (Pin 1, 17) VCC (Pin 2) VDD

- NC (Pin 3) -

- Signal (Pin 4) A0

SCL (Pin 5) SCL -

SDA (Pin 3) SDA -

Wiring:

This soil moisture sensor is an analog sensor.
Since the Raspberry Pi has no analog inputs, you must use an an-

alog-to-digital converter.
In this example the ADC COM-KY053 from Joy-it is used.

2. INBETRIEBNAHME MIT DEM RASPBERRYPI

Code example:

The higher the analog input voltage, the higher the measured humidity.
The range of values is from 0 to 3.3
In the following code example, the analog value of the sensor is read out every 5 seconds

and output in the console.

from time import sleep
import board
import busio
import adafruit_ads1x15.ads1115 as ADS
from adafruit_ads1x15.analog_in import AnalogIn
import RPi.GPIO as GPIO

# Create the I2C bus

i2c = busio.I2C(board.SCL, board.SDA)

# Create the ADC object using the I2C bus

ads = ADS.ADS1115(i2c)

# Create single-ended input on channels

chan0 = AnalogIn(ads, ADS.P0)
chan1 = AnalogIn(ads, ADS.P1)
chan2 = AnalogIn(ads, ADS.P2)
chan3 = AnalogIn(ads, ADS.P3)

try:

while True:
print("{:>5.3f}".format(chan0.voltage))
sleep(5)

except KeyboardInterrupt:

GPIO.cleanup()

Installation:

To be able to use the ADC, you must first enable I2C.
Enter the following command:

Navigate to Interfacing Options -> I2C and enable the I2C interface.

You must also install the Python library of the ADC.
Enter the following command:

sudo raspi-config

sudo pip3 install adafruit-circuitpython-ads1x15

3. COMMISSIONING WITH THE ARDUINO

Arduino Moisture

GND GND (Pin1)

5V VCC (Pin2)

NC NC (Pin3)

Analog Pin A0 Signal (Pin4)

Wiring:

Code example:

The higher the analog input signal, the higher the measured humidity.
The range of values is from 0 to 1023
In the following code example, the analog value of the sensor is read out every 5 seconds and displayed

in the serial monitor.
Before uploading, make sure that you have set the correct board and port in your Arduino IDE.

void setup() {

Serial.begin(9600);
pinMode(A0, INPUT);
}

void loop() {

Serial.println(analogRead(A0));
delay(5000);
}
