Raspberry with Maxbotics

[Jen]

I have tried Raspberry Pi with Ultrasonic HCSR 04 Sensor. I have written a program for that. I got a proper result, but I am facing some reliability issue with that. So I thought I will use other sensors.

Statement 2: I bought Maxbotics sensor MB 1040. I have written program in python, I got readings but that is not proper reading, I have not achieved accuracy. Kindly assist me solve this issue. Here I have attached program

import time
import RPi.GPIO as GPIO

GPIO.setmode(GPIO.BCM)
GPIO_TRIGECHO = 15

print "Ultrasonic Measurement"

GPIO.setup(GPIO_TRIGECHO,GPIO.OUT)
GPIO.output(GPIO_TRIGECHO, False)

def measure()

GPIO.output(GPIO_TRIGECHO, True)
time.sleep(0.00001)
GPIO.output(GPIO_TRIGECHO, False)
start = time.time()

GPIO.setup(GPIO_TRIGECHO, GPIO.IN)
while GPIO.input(GPIO_TRIGECHO)==0:
    start = time.time()

while GPIO.input(GPIO_TRIGECHO)==1:
    stop = time.time()

GPIO.setup(GPIO_TRIGECHO, GPIO.OUT)
GPIO.output(GPIO_TRIGECHO, False)

elapsed = stop-start
distance = (elapsed * 34300)/2.0
time.sleep(0.1)
return distance

try:
while True:
distance = measure()
print " Distance : %.1f cm" % distance
time.sleep(1)

except KeyboardInterrupt:
print("Stop")
GPIO.cleanup()

Hi @Jen,

I think you might be in the wrong place! These forums are for the Pycom (https://pycom.io) products such as the WiPy, LoPy, etc.

It seems as though you are using the Raspberry Pi which uses a different version of Python from that found on our devices! I'll point you towards https://www.raspberrypi.org/forums/ to find some more support for your issue!

Thanks!
