Tutorial: How to use Resistive Pressure Sensor BF350

The resistive pressure module BF350 is an essential component for measuring pressure in various devices and projects. Ideal for beginner makers who want to explore applications such as climate control or atmospheric pressure monitoring.

What you need

• Arduino Uno
• USB A-MicroB cable
• Soldering pliers (if necessary)
• 10kΩ resistor

Steps

1. Connect the BF350 module to the Arduino using cables connected to the VCC, GND, and SIG pins.
2. Check that the 10kΩ resistor is connected between VCC and SIG of the module to form a voltage divider.
3. Download the Arduino IDE software and install necessary libraries such as Adafruit_BMP280 or similar (check the datasheet).
4. Compile a simple sketch that reads values from the SIG pin of the module.
5. Upload the sketch to the Arduino using the USB cable.
6. Open the Serial Monitor section of the Arduino IDE to view the received pressure data.
7. Verify data integrity by comparing it with a reference barometer or weather station.
8. Adapt the sketch and connections based on the project requirements.

Example code

void setup() {
  Serial.begin(9600);
}

void loop() {
  int val = analogRead(A0); // Leggi dal pin SIG
  float voltage = val * (5.0 / 1023.0); // Converte in tensione
  Serial.println(voltage);
}

Mini project

Create an atmospheric pressure monitoring system that sends data over the internet using ESP8266.

Common mistakes

• Do not connect the resistor between VCC and SIG.
• Use an input voltage different from 5V without proper adjustment.
