This code reads the current status of the sensor and displays in the
console whether an obstacle is present or not. If the sensor detects an
obstacle, another LED (Sled) lights up.
The sensor has two potentiometers with which the
sensitivity of the receiver as well as the transmitter can be adjusted.
You can also download this sample code here.
First, you have to install this package:
wget http://sensorkit.joy-it.net/images/d/d8/KY-032_RPi_HindernisDetektor.zip
unzip KY-032_RPi_HindernisDetektor.zip
2. Code example
# Required modules are imported and set up
import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BCM)
# The input pin to which the sensor is connected, is declared here.
GPIO_PIN = 24
GPIO.setup(GPIO_PIN, GPIO.IN, pull_up_down = GPIO.PUD_UP)
# Pause between the output of the result is defined (in seconds)
delayTime = 0.5
print ("Sensor-Test [druecken Sie STRG+C, um den Test zu beenden]")
# Main loop of the program
try:
while True:
if GPIO.input(GPIO_PIN) == True:
print ("No obstacle")
else:
print ("Obstacle detected")
print ("---------------------------------------")
# Reset + Delay
time.sleep(delayTime)
# Clean up after the program has finished
except KeyboardInterrupt:
GPIO.cleanup()
sudo apt install python3-rpi.gpio
Now, you can either use the following commands to download and unzip
the file :
Or you can create a new file with the following command and copy the
example code described into it:
sudo nano KY-032_RPi_HindernisDetektor.py

Now, you have to save the file with CTRL + O and press Enter to confirm.
Press CTRL + X to exit the editor again.
With both variants, the program will be performed as follows:
sudo python3 KY-032_RPi_HindernisDetektor.py

2. Code example
This code reads the current status of the sensor and displays in the
console whether an obstacle is present or not. If the sensor detects an
obstacle, another LED (Sled) lights up.
int Sensor = 10; // Declaration of the sensor input pin
void setup (){
Serial.begin(9600); // Initialization serial output
pinMode (Sensor, INPUT) ; // Initialization of sensor pin
}
// The program reads the current status of the sensor pin and
// displays in the serial console whether an obstacle is currently detected
// or if there is no obstacle in front of the sensor
void loop (){
// The current signal at the sensor is read out
bool val = digitalRead (Sensor) ;
// If a signal could be detected, the LED is switched on.
if (val == HIGH){
Serial.println("No obstacle");
}
else {
Serial.println("Obstacle detected");
}
Serial.println("------------------------------------");
delay(500); // Pause between the measurement of 500ms
}
In this code example, the received data is issued on the serial
Monitor. Make sure that the baud rate is set correctly (9600).
Also make sure that you have set the right board and port in your Arduino
IDE before uploading.
You can also download the code example here.
The sensor has two potentiometers with which the sensitivity of the
receiver as well as the transmitter can be adjusted.
5. ENABLE - PIN
This sensor has an additional pin called Enable. This pin oers the
possibility to activate o to disable the sensor via a controller. By default
this is activated by means of a jumper. This means that the obstacle
detection is always performed. If you want to deactivate the permanent
detection, remove this jumper (EN) and connect the enable pin to a pin
with which a control signal can be sent.
