Smart Pss Raspberry Pi May 2026

import RPi.GPIO as GPIO import time TRIG = 23 ECHO = 24 THRESHOLD = 0.7 # meters (70cm)

⚠️ The HC-SR04 ECHO pin outputs 5V. Use a voltage divider (two resistors) to step it down to 3.3V, or use a logic level converter to avoid frying your Pi. Step 2: Write the Python Script Here’s a simple, production-ready script: smart pss raspberry pi

while GPIO.input(ECHO) == 0: pulse_start = time.time() while GPIO.input(ECHO) == 1: pulse_end = time.time() import RPi
