pi-node

This repository contains the source code for a simple Node.js application that runs on a Raspberry Pi. The application listens for incoming HTTP requests and responds with a message indicating the current temperature and uptime of the Raspberry Pi.

Prerequisites

To run this application, you will need the following:

1. A Raspberry Pi with Node.js installed
2. A temperature sensor (such as a DS18B20) connected to the Raspberry Pi

Getting Started

1. Clone this repository to your Raspberry Pi:

git clone https://github.com/KOSASIH/pi-node.git

2. Install the required dependencies:

cd pi-node
npm install

3. Edit the config.js file to specify the temperature sensor's device file path. For example, if you're using a DS18B20 connected to GPIO pin 4, the device file path will be /sys/bus/w1/devices/28-000005f8b8ff/w1_slave.

4. Start the application:

npm start

5. Use a web browser or a tool like curl to send an HTTP request to the Raspberry Pi and view the response:

curl http://<RASPBERRY_PI_IP_ADDRESS>:3000

The response will look something like this:

Temperature: 23.5°C, Uptime: 1 day, 2 hours, 34 minutes, 56 seconds
