Indoor monitoring using Raspberry Pi
Introduction
This is Qiita's first post. Thank you.
Suggestion
I wanted to make an inexpensive monitoring system with Raspberry Pi and sensors. Specifically, it is a monitoring system that installs RaspBerryPi Zero, RaspBerryPi camera, and motion sensor (HC-SR501) in the laboratory, takes a picture with a camera when a person is detected, and sends the image to Slack (unfinished).
Equipment used
・ Raspberry Pi zero ・ Raspberry Pi camera ・ HC-SR501 Human body infrared sensitive module ・ 3 jumper wires (female / female)
Implementation
If the motion sensor detects a person, the program to shoot with the Raspberry Pi camera is as follows.
monitoring.py
import time
import picamera
import RPi.GPIO as GPIO
INTERVAL = 5
SLEEPTIME = 1
GPIO_PIN = 18
GPIO.setmode(GPIO.BCM)
GPIO.setup(GPIO_PIN,GPIO.IN)
if __name__ == '__main__':
try:
print("CTRL to cancel processing+C")
while True:
if(GPIO.input(GPIO_PIN) == GPIO.HIGH):
with picamera.PiCamera() as camera
camera.resolution = (1024,768)
camera.brightness = 70
camera.capture('picture.jpg')
else:
time.sleep(INTERVAL)
except KeyboardInterrupt:
print("All processing finished")
finally:
GPIO.cleanup()
Execution result
I built a local web server and confirmed that the images were acquired.
in conclusion
Currently, this system is incomplete because the process of sending data to Slack has not been implemented. After implementation, I would like to pursue the usefulness of this system by comparing it with other monitoring systems.
