Hey thanks for answer.
First, system shuts down at 100°C, because I turn down the oven. I didn't want to cause any damage, nor wait too long.
Second, time is in seconds, not milliseconds.
Once you I the 60% of the full scale, and the best fit towards zero and than subtract delay time, that is...
Hello guys,
I'm beginner in automatics and could use your advice.
So, I'm designing a PID regulator for oven and right now I'm trying to tune the Kp, Ki and Kd parameters. The oven has nice step response that gets easily approximated by the PT1 system with the dead time delay.
The system to...
So, basically I need very fast solution cause I have no time to wait for real programmer, as USBtiny. I have Arduino Duemillanove and I know I can use it as an ISP. I already used it to burn the arduino bootloader on my Atmega8.
The problem is, I have a source code in c++ that needs to end up...
Nope... I can communicate nicely via serial port using AT comands.
The LED lamp which should indicate successful connection to the network does not behave like it is connected (it should blink every second if there is no connection and every 3 sec if there is one. I get blink every second)
Instead of buying "normal" GSM module that is used for Arduino, I purchased this **broken link removed**. It seemed cheaper and easier to work with. I connected voltage supply and RX/TX pins and started playing with it. But for some reason it doesn't want to estabilish connection with my GSM...
Thanks, this makes a lot of sense. But then again, in most of the low frequency electronics, in.e. audio cirucuits, input of the amplifier is never matched to the TXLine, but we see no such effects as reduction of the amplitude at the output. I know that people will say that on low frequency...
So, imagine signal propagating through the 50 Ohm coax cable (TXLine) on which end there is simple transistor amplifier with really high input impedance. Unmatched, as you can imagine. What I know is that reflection is gonna happen on this end and signal will return to the TXLine. What will I...
Thanks for answer Brad!
But, could you be so nice and provide me some explanation of why is this method legitimate? Or, link some references if it's easier for you.
Glad I could help. Regarding precision, well this type of the sensor is not very sophisticated...though it can give you rough estimation which is quite useful in some applications.
I think he plans to measure only one substance's concentration.
Anyway, bilal, I haven't worked with MQ-2, but I have some experience with MQ-3, and I think they are the same type of sensor. How to work with it - first you need to find the resistance of the sensor in gas free environment, and...
