This is what the Flux documentation says about the topic:
"Defines a set of widths which will show up in the Context Menu for easy access. The keyboard shortcut W will cycle through the set.
Example 1: Suppose you know you will be alternating between routing power traces and data traces. Add the Preferred Trace Width Rule to the Object-specific Rules of the Nets object located in the Objects panel. Then, in the entry box input the desired widths of these two types of traces, (150um and 500um for example). When routing, press w to easily alternate between these trace widths."
To connect your analog pressure sensor to the ESP32-WROVER-E, we need to consider the following:
Input Voltage: The sensor operates at 5V, while the ESP32-WROVER-E typically operates at 3.3V for GPIO. We need to power the sensor with 5V while also interfacing its analog output to the ESP32.
Analog Output: This sensor provides an analog output, which means you'll use one of the ESP32's ADC (Analog-to-Digital Converter) pins to read it.
Three-Wire Output Pattern: This typically indicates a power, ground, and signal wire.
Voltage Level Shifting (if needed): The analog output of the sensor could be higher than 3.3V, so we might need a voltage divider to step down the voltage for safe ADC reading if it exceeds 3.3V.
Assuming you're using the sensor with a 0-5V output range and want to connect it to the ESP32, here's how you might proceed. If the output range is different, please let me know:
Connections:
Power: Connect the sensor's power wire to the +5V net in your circuit (VCC).
Ground: Connect the sensor's ground wire to the GND net.
Signal: Connect the sensor's analog output to one of the ESP32’s ADC pins. For this example, we will use IO36, which is an ADC pin.
Here's how you can wire it up:
Connect the sensor power to +5V:
Sensor:VCC to VBUS:P1
Connect the sensor ground to GND:
Sensor:GND to ESP1:GND
Connect the sensor signal to the ESP32's ADC:
Sensor:Signal to ESP1:IO36
These connections effectively power the sensor from the 5V rail and read from the analog output using one of the ESP32's ADC pins.
If the output is 0-5V and you need to scale it to a 0-3.3V range, you might consider a voltage divider on the signal line before connecting it to the ESP32's ADC pin.
Would you like help designing that voltage divider or any other part of this connection?
