Interfacing Water Flow Sensor with Raspberry Pi 3 ๐Ÿšฟ

๐ŸŽฏ Objective

To measure the flow rate of water using a Water Flow Sensor (YF-S201) and Raspberry Pi 3. Useful in smart irrigation and water management systems.

๐Ÿงฐ Components Required

ComponentQuantity
Raspberry Pi 31
YF-S201 Water Flow Sensor1
10K Pull-down Resistor1
Jumper WiresAs required
Breadboard1

⚡ Circuit Connections

Sensor PinConnect To
Red (VCC)5V (Raspberry Pi)
Black (GND)GND (Raspberry Pi)
Yellow (Pulse Out)GPIO18 (Pin 12) with pull-down resistor

๐Ÿง  Python Code

import RPi.GPIO as GPIO
import time

FLOW_SENSOR = 18
pulse_count = 0

def countPulse(channel):
    global pulse_count
    pulse_count += 1

GPIO.setmode(GPIO.BCM)
GPIO.setup(FLOW_SENSOR, GPIO.IN, pull_up_down=GPIO.PUD_DOWN)
GPIO.add_event_detect(FLOW_SENSOR, GPIO.FALLING, callback=countPulse)

try:
    while True:
        pulse_count = 0
        time.sleep(1)
        flow_rate = (pulse_count / 7.5)  # for YF-S201
        print(f"๐Ÿšฟ Flow Rate: {flow_rate:.2f} L/min")

except KeyboardInterrupt:
    GPIO.cleanup()

๐Ÿ“Š Output

  • Shows live flow rate of water in liters per minute.
  • Pulse count is converted to flow using the sensor's spec.

๐Ÿ’ก Applications

  • Smart irrigation systems
  • Water conservation projects
  • Leak detection and usage monitoring

TOUCH PLATE BASED DOOR BELL

Title:  Touch plate based door bell  Circuit:  Components: IC 555 Resistors: 1 M, 100k, 330 ohms Transistor: BC547  PN2222A Capacitor: 10n 1 Copper plate : as touch plate. A 6v battery An LED / Ic UM66 Description: This is the simple circuit for touch plate based security system. In this project what basically done is, circuit detects stray voltages produced by mains voltage and electrostatic built  up in the room.If sufficient static voltage is detected by the plate then chip will charge up. Transistor BC 547 or PN2222A is used basically to increase the sensitivity.In place of led just connect IC um 66(melody IC). Applications: In homes, of course. This can be specially used in places like hospitals, when patients need to call doctor by himself.

Interfacing Load Cell with Raspberry Pi 3 (via HX711) ⚖️

Interfacing Load Cell with Raspberry Pi 3 (via HX711) ⚖️ Interfacing Load Cell with Raspberry Pi 3 (via HX711) ⚖️ A load cell is a transducer that converts force (weight) into an electrical signal. The HX711 is a precision 24-bit analog-to-digital converter (ADC) designed for weigh scales.

Interfacing Sound Sensor with Raspberry Pi 3

๐Ÿ”น Overview The KY-037 is a high-sensitivity sound detection sensor that can detect noise levels in the environment. It provides both analog and digital outputs. In this tutorial, we’ll interface the digital output of KY-037 with Raspberry Pi 3 Model B+ (without using an ADC like MCP3008) and detect sound events.
