Introduction: Crash Detection Module Based on MPU6050 and Raspberry Pi Pico
This is a project based on accelerometer to detect and alert the in event of a vehicle crash or accident.
Supplies
Raspberry Pi Pico
MPU6050 module
Active Buzzer
Breadboard
Solid core wires
Micro USB cable
Step 1: Do the Wiring As Shown in the Schematics
Do the wiring and note the GPIO pins you are using for later use in writng code
Step 2: Install Thonny and Configure It for Programming Pi Pico
Install thonny from provided link from here
Step 3: Configure Raspberry Pi Pico
Hold the bootsel button while connecting raspberry to the computer.Open thonny and go tools> options>interpreter>micropython(raspberry pi pico)
Step 4: Upload the Code and Enjoy :)
from imu import MPU6050
import time
from machine import Pin, I2C
i2c = I2C(0, sda=Pin(0), scl=Pin(1), freq=400000)
imu = MPU6050(i2c)
buzzer = Pin(16, Pin.OUT)
ax=[0,0]
ay=[0,0]
az=[0,0]
while True:
ax[0]=(imu.accel.x)
ay[0]=(imu.accel.y)
az[0]=(imu.accel.z)
ax[1]=(imu.accel.x)
ay[1]=(imu.accel.y)
az[1]=(imu.accel.z)
if abs(ax[0]-ax[1])>1 or abs(ay[0]-ay[1])>1 or abs(az[0]-az[1])>1 :
buzzer.toggle()
time.sleep(0.1)
buzzer.toggle()
print(abs(ax[0]-ax[1]), abs(ay[0]-ay[1]),abs(az[0]-az[1]))
