DSM501 Arduino Library

This Arduino library provides support for working with the DSM501 particulate matter sensor. It allows you to easily interface with the sensor and read particulate matter concentrations.

Installation

1. Download this repository as a ZIP file.
2. In the Arduino IDE, go to Sketch > Include Library > Add .ZIP Library....
3. Select the downloaded ZIP file.
4. The library is now installed and ready to use.

Usage

1. Include the library at the top of your Arduino sketch:

   #include "DSM501.h"
   

2. Create an instance of the DSM501 class and specify the pin number and an interrupt handler function:

   int sensorPin = 2;  // Replace with your actual sensor pin
   DSM501 dsm501(sensorPin, yourInterruptHandler);
   

3. Implement your interrupt handler function. This function will be called on each state change of the sensor's output pin:

   void yourInterruptHandler() {
   dsm501.handleInterrupt();
   }

4. In your Arduino setup() function, initialize the sensor:

   void setup() {
   Serial.begin(9600);
   // Other setup code...
   dsm501.isReady(); // Warm-up the sensor
   }

5. In your loop, you can read particulate matter concentrations:

   void loop() {
   float pmConcentration = dsm501.readPM();
   // Do something with the concentration value (e.g., display it or send it over a network)
   delay(1000); // Adjust the delay as needed
   }

Example
