Thank you for your reply. I would definitely add something like you suggested. I also found that it happens when sensor returns more then 3.3v response and with a resistor between echo and pin seems solved my problem.

Yes i picked up distance function from forums. I dont know how to work the sensor without this code. Could you just tell me errors in this code?

Hi, I am trying to make a Tachometer with hc-sr04 proximity sensor. It is working normal for 3-4 hours and then it freezes. No error, no run, nothing, just standing still. Here is my code, import RPi.GPIO as GPIO import time import pymssql #GPIO.cleanup() GPIO.setmode(GPIO.BOARD) TRIG = 18 ECHO = 16...

my adc is mcp3202. I dont have enough electronic knowladge so i dont sure that i connected them correctly. Do you have any reference for connecting mpx10dp, ina128 and mcp3202?

Hi, I have a project with mpx10dp water pressure sensor to read water pressure. To read it i got ina128 amplifier and analog to digital converter. I am trying to read values but i couldn't get any. Is there any driver install for this to run before or maybe you could give me some examples for it? An...

Ok, i'll try it. Thank you.
