Sensor API

This project contains two Rust applications for reading sensor data from BME280 and PMSA003I sensors using the I2C bus and exposing the data through a web API using Actix-web.

BME280 Sensor Application

The BME280 application reads temperature, humidity, pressure, and altitude data from a BME280 sensor.

How to Run

1. Navigate to the bme280 directory:

2. Navigate to the bme280 directory:

   cd bme280

3. Build the project:

   cargo build

4. Run the project:

   cargo run

API Endpoint

• GET /sensor_data: Returns the sensor data in JSON format.

Example Response

{
    "timestamp": "2023-10-01T12:00:00Z",
    "model": "BME280",
    "temperature": 25.0,
    "humidity": 40.0,
    "pressure": 1013.25,
    "altitude": 100.0
}

PMSA003I Sensor Application

The PMSA003I application reads particulate matter concentrations (PM1.0, PM2.5, PM10) from a PMSA003I sensor.

How to Run

1. Navigate to the pmsa003i directory:

   cd pmsa003i

2. Build the project:

   cargo build

3. Run the project:

   cargo run

API Endpoint

• GET /sensor_data: Returns the sensor data in JSON format.

Example Response

{
    "timestamp": "2023-10-01T12:00:00Z",
    "model": "PMSA003I",
    "pm1_0": 10,
    "pm2_5": 20,
    "pm10": 30
}

Common Dependencies

Both applications use the following common dependencies:

• actix-web: For building the web server and handling HTTP requests.
• linux_embedded_hal: For hardware abstraction layer (HAL) implementations.
• serde: For serializing and deserializing data.
• chrono: For handling date and time.
