Temperature Measurement Using 8051 Microcontroller

Click For Summary

Discussion Overview

The discussion revolves around designing a temperature measurement device using the 8051 microcontroller, specifically focusing on the integration of the DS1620 temperature sensor. Participants are exploring the necessary components, programming, and circuit design involved in this project.

Discussion Character

  • Technical explanation
  • Homework-related

Main Points Raised

  • One participant requests assistance with designing a temperature measurement device and asks for a circuit diagram.
  • Another participant emphasizes the importance of self-sufficiency in learning and asks several clarifying questions regarding programming skills, electronics knowledge, sensor choice, temperature range, and output type.
  • A participant identifies themselves as a B.Tech final year student in Electronics and Instrumentation Engineering and confirms their ability to program, specifying the use of the DS1620 sensor and the 89C52 microcontroller.
  • Another participant suggests reviewing the datasheet for the DS1620, noting its digital nature and the requirement for a 3-Wire Communications Protocol for data transmission, and encourages practical experimentation with the components on a breadboard.

Areas of Agreement / Disagreement

Participants generally agree on the need for the requester to engage with the project actively and to utilize datasheets for guidance. However, there is no consensus on the specific implementation details or circuit design, as the discussion remains exploratory.

Contextual Notes

Participants have not resolved specific questions regarding the circuit design or programming details, and there are assumptions about the requester's prior knowledge and experience that remain unverified.

Who May Find This Useful

Students or individuals interested in microcontroller projects, temperature measurement systems, or those studying electronics and instrumentation engineering may find this discussion beneficial.

Welcome to PhysicsForums!

Unfortunately, we don't do your work for you here. However, we will help you help yourself!

  • Can you program?
  • Do you know much about electronics?
  • Do you know what type of sensor you want to use (you need one), or where you need to take readings (fluid, surface, etc.)?
  • What temperature range you're likely to see?
  • What kind of output do you want?

If you answer no or don't know to a lot of these questions, and you need this pretty soon, you may be better off buying an appropriate temperature measurement device.
 
thanks for replying...i m a B.tech Final Year student in Electronics nd instrumentation engineering
  • yes i can do the programing part...
  • Sensor (to be used)--->DS1620
  • Micro controller (to be used)---->89c52
 
Well, as a final year B.Tech in instrumentation and electronics, you should be able to do this (at least in general).

Start by looking at the datasheet for the sensor:
http://datasheets.maxim-ic.com/en/ds/DS1620.pdf

Clearly, this is a digital device and doesn't require you to sample an analog voltage via your ADC (Analog to Digital Converter). It also tells you that you'll need to use their 3-Wire Communications Protocol, using Reset, Data (Bidirectional) and Clock. Data is bidirectional, which means you'll need to use the same pin (on your 8051) to transmit and receive data.

Now, put the 8051 and the DS1620 on a breadboard, wire them up, and try to get them communicating with one another. You'll need the datasheet for the 89c52:

If you have specific questions, we can try to help you through them, but we can't do your task for you!
