Discussion Overview

The discussion revolves around developing an application to receive signals from a heat sensor, specifically focusing on sending alerts to an Android phone. Participants explore various programming tools, communication methods, and hardware components necessary for the project, which involves a microcontroller.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Homework-related

Main Points Raised

  • One participant inquires about suitable app programming tools for Android, expressing a lack of prior experience in app development.
  • Some participants suggest using Bluetooth for communication if proximity to the sensor is sufficient, while others propose an Internet-based solution for remote alerts.
  • A participant mentions the need for the sensor to trigger an alarm when a certain temperature threshold is exceeded, clarifying the project's requirements.
  • There is a discussion about the limitations of using certain hardware like Raspberry Pi or Arduino, with one participant expressing uncertainty about how minimal the setup needs to be.
  • Another participant describes a plan to use a SIM900 module to send text alerts, outlining the necessary components for this approach, including a microcontroller and power supply.
  • Some participants recommend researching similar projects online to gather ideas and understand the required actions for the microcontroller.
  • There is a debate about the practicality of using prebuilt setups versus designing a custom solution, with differing opinions on cost-effectiveness and efficiency.

Areas of Agreement / Disagreement

Participants express various viewpoints on the best approach to the project, with no consensus on the ideal communication method or hardware setup. Some agree on the utility of researching existing projects, while others emphasize the importance of understanding project requirements before proceeding.

Contextual Notes

Participants note the ambiguity in project requirements and the potential need for further clarification. There are also discussions about the trade-offs between using prebuilt components versus custom designs, highlighting the complexity of the project.

TL;DR
I need to develop an app that will receive a signal from a heat sensor to ring the phone when temperature is too high. What programming would I need to use? Can that programming receive signals?
I was assigned a project where I need to have a heat sensor send a signal to my phone and cause it to sound an alarm. If my phone is an android what is a good app programming tool for this project, I’ve never done app programming. Would I be able to send a signal from the sensor to the phone? Lastly, I will be using a micro controller in the project too. Any help is appreciated.

Do you only care when you are near the temperature sensor? If so, you could connect to it via Bluetooth.

If not, you will need an Internet-type application, similar to home control apps, I believe.

Ah yes, we were planning on using bluetooth. Sorry but I made myself unclear, the sensor will need to detect whether the temperature of a room has gone up a certain value and ring the user's phone if it does. Also I might have to make this more barebones than just buying a bluetooth enabled sensor itself although I would have to ask my instructors.
 
Do you know domoticz?

No, why?

I can’t use raspberry pi or Arduino either.

You are making us guess too much. How barebones? Do you need to design your own bluetooth chips?

Problems like this can sometimes be cleared up by posting the complete statement of the project requirements.

You are correct, I myself don't know how barebones it has to be. I will try asking again once I have a better understanding, thank you for your time.
 
I will be sending a warning text to a phone by using a sim900. I have seen that there are prebuilt setups with the sim900 chip, Sim card reader, antennae, audio ports, etc but I only want to send texts and tell the sim900 when to send one. I could buy the presets and just use the texting functionality but this is for an engineering project and it seems like a waste of money to buy something that you won't use. So my question is, what would I need to send a text? My guess would be a sim900 chip, a Sim card, Sim card reader, a microcontroller (I'm not allowed to use Arduino/pi), and power supply. For context, I will be measuring the temperature of a car with a thermometer, when it reaches a certain temperature then the sim900 should send a text to the owner's phone.

Have you looked at projects of this sort online? I would start there.

I know many use Arduino but the other components should be the same and you can get an idea of how to do it and what specific actions your microcontroller will need to do to make it work.

All of them just use the presets circuits with the sim900 and peripherals.

Depends. For a single device or prototyping it is often much faster, easier and cheaper to use something ready (ignoring parts of the functionality) than to start from scratch (you save on designing, debugging and manufacturing). When you want to go to the mass production then yes, saving a cent per unit can be a worthy endeavor.
