@copilot How to make a temperature and humidity monitoring device?

Sure, I can guide you to create a schematic for a temperature and humidity monitoring device using Flux.
A common setup for a temperature and humidity monitoring device can be done using a DHT11 or DHT22 sensor for temperature and humidity measurement. We already have the DS18B20+ Temperature Sensor covered for temperature, which you may prefer to use due to its digital interface and precision.
Let's add the DHT22 sensor to measure humidity. Note that the DS18B20+ and the DHT22 both work with a microcontroller, which will act as the controller of the device. Here, as an assumption, I'm going to suggest an Arduino UNO, which can be programmed with a variety of features you might want to use.
Connections for the DHT22 sensor to Arduino UNO:
  • Connect pin 1 (VCC) of the DHT22 to 5V of the Arduino
  • Connect pin 2 (Data) of the DHT22 to a digital pin of the Arduino, let's say, digital pin 2
  • Connect pin 4 (Ground) of the DHT22 to GND of the Arduino
Connections for the DS18B20+ sensor to Arduino UNO:
  • Connect pin 1 (GND) of the DS18B20+ to GND of the Arduino
  • Connect pin 2 (DQ) of the DS18B20+ to a digital pin of the Arduino, let's say, digital pin 3
  • Connect pin 3 (VDD) of the DS18B20+ to 5V of the Arduino
You'll need a 4.7 kOhm pull-up resistor between the DQ line (middle pin) and VCC (right pin) for the DS18B20+.
It's worth noting that both DS18B20+ and DHT22 sensors communicate via a 1-Wire interface so you'll need to include a library to handle this in your microcontroller code.
You'll need to add these components and wire them up in your Flux project to complete the schematic. After that, you'll need to load code onto the Arduino to read the sensor data and implement your monitoring logic, which could include threshold-based alerting, data logging, data transmission, etc.
Please note that all these connections and specifications are assumed to be standard unless specified otherwise. If you have more specific needs, please let me know!

Creating or providing graphics or visual drawings may not always be possible, but guidance through the process of creating a PCB layout using Flux.ai or any other PCB design software is.
First, you should finalize your schematic. Once you are happy with your schematic, transfer it to a PCB layout by following these steps:
  1. From the schematic view in Flux.ai, click on "Board mode" or "Switch to PCB" to switch to the PCB design environment.
  2. Position your components. You will see representations of all your components linked by golden lines representing the electrical connections defined in the schematic.
  3. Position your components on the board based on logical groupings of components, keeping related components near each other, and considering the mechanical constraints of your enclosure if one is being used.
  4. Route your PCB. Replace the golden lines with copper traces. This can be done either manually or using an auto-router if your software has one. The width of your tracks will depend mainly on the amount of current they will carry and the manufacturing capabilities of your PCB fab.
  5. After all the routing is done, add silkscreen labels as needed. This step is not strictly necessary but can be useful for assembly and debugging. The silkscreen is usually used to indicate component designators, polarity for polarized components, any test points, company logos, etc.
  6. Run a design rules check (DRC) to confirm the PCB layout meets all the manufacturing requirements.
This is a general guideline and specifics might vary based on your exact design and the software you are using. Your choice of components and the complexity of your design could also add further considerations that are not covered here.

I'm an AI assistant, so while I can provide guidance on designing an electrical schematic, I'm not able to directly create or draw them. However, I can explain how you could potentially do this in your Flux project:
From your project details, it seems you have a DS18B20+ temperature sensor and associated elements. You haven't listed a microcontroller, so let's assume you will be using an Arduino UNO.
Here's a step-by-step guide on how to design a basic schematic:
  1. Arduino UNO: Start by adding an Arduino UNO to your schematic. Label it as U1.
  2. Power Supply: Connect the 5V and GND pins from Arduino to your power supply rails in the schematic. You can designate these power supply symbols as VDD for the 5V supply and GND for ground.
  3. DS18B20+ Sensor: Next, add the DS18B20+ temperature sensor to your schematic. Designate it as U2.
    • Connect GND pin of DS18B20+ to the GND of your power supply.
    • Connect VDD pin of DS18B20+ to the VDD of your power supply.
    • Connect DQ pin of DS18B20+ to a digital I/O pin on Arduino (let's assume pin D10).
  4. PULL-UP Resistor: Add a 4.7k ohm pull-up resistor (R1) between VDD and DQ pins of the DS18B20+ sensor.
Your barebones temperature sensing schematic is now complete. A couple of things to note:
  • This is a very basic schematic. In a practical design, you would likely need additional components such as decoupling capacitors, a programming interface, and potentially, other interfaces compatible with a digital bus.
  • The designated names/numbers, such as U1, U2, R1, etc., can be changed as you like. These are just suggested IDs.
In Flux.ai, you can find all the elements from the common parts library and wire everything accordingly. In case you can't find a component, you can add your custom parts.

As a text-based AI, I don't have the ability to directly interact with the Flux.ai website or any other third-party platform. But I can guide you on how to import the components into your Flux.ai project:
Let's import your required components for the project:
  1. Arduino UNO:
    On the Flux.ai interface, go to the component library. Select the MCU category and search for Arduino UNO. Click Import, and the component will be added to your project.
  2. DS18B20+ Temperature Sensor:
    You can find the DS18B20+ under the sensors category. If it's not there, you may check under common parts. Import it into your project.
  3. Pull-up Resistor (4.7k Ohm):
    Navigate to the resistors category and import a 4.7k Ohm resistor into your project.
After you've imported all the components, you can place them onto your schematic and make the appropriate connections as described in earlier steps.
Remember, if any of these components are not available in the Flux.ai library, you can always create custom parts in the interface. Custom parts come with their own learning curve, but there are numerous helpful guides online that can walk you through the process.
Please note, it's always essential to verify the datasheets of the components you are using to ensure they meet your project's specific requirements.

@copilot how to make logger?
2y

copilot

To make a temperature logger using the DS18B20+ sensor on your project, you will need the following components:
  • Microcontroller (MCU), such as the Arduino UNO
  • Resistors
  • SD card module for data storage
  • Breadboard and jumper wires for connections
Here's a simplified process on how to make a logger:
1. Set up the DS18B20+ sensor: Connect the DS18B20+ pins to your MCU and a 4.7k ohm Pull-Up resistor:
  • DS18B20+ GND to MCU GND
  • DS18B20+ VDD to MCU 3.3V or 5V (depending on your MCU)
  • DS18B20+ DQ to a Digital GPIO on your MCU (for example, D2 on Arduino UNO)
  • Connect a 4.7k ohm Pull-Up resistor between VDD and DQ pins of DS18B20+
2. Set up the SD card module:
  • Connect the SD card module's MISO, MOSI and SCK pins to the SPI pins on your MCU (on Arduino UNO, these are pins 11,12 and 13 respectively)
  • Connect the SD card CS/SS pin to a digital pin on your MCU (for example, pin 10 on Arduino UNO)
  • Connect VCC to 5V and GND to GND
3. Programming the MCU:
  • First, ensure the OneWire and DallasTemperature libraries are installed in your Arduino IDE (needed to interface with the DS18B20+ sensor)
  • Then write a code that reads the temperature from the DS18B20+ sensor in a timed interval and logs it to the SD card. Use the SD library from the Arduino IDE to read and write to the SD card.
Remember, you will need to establish the correct connections in your Flux.ai project as per the connections described above. Also, please pay attention to the power requirements of each of your components.
Is there a specific detail you would like to dive deeper, such as a choice of microcontroller, resistor values, or programming structure?
