DHT11-API

A very basic nodejs REST api to store data from a DHT11 module using mongodb. Basically send your data from your client to a server and store it in a database. Useful for remote-access to the data. I used this to monitor our temperature & humidity in our office with a raspberry-pi

Installation

• Install nodejs
• Install npm
• Clone or download this repo
• Run npm install in the root directory of this repo
• Add a /config/ folder and create a db.js file in it
• Add this code to your db.js file:

module.exports = {
    url : <username>:<password>@<your-database-ip>
}

• Run npm start in the root directory of this repo

Usage

This API requires a specific data pattern in x-www-form-urlencoded form:

• id: the id of your client. This is designed to support multiple clients. Just choose a unique one for each one. Can be a numer like 1 or a string like livingroom
• time: a timestamp in the following format: yyyy-MM-dd HH:mm:ss.ffffff where y = year, M = month, d = day, H = hour, m = minute, s = second, f = fraction of second
• temp: your temperature measurement
• hum: your humidity measurement Just send POST requests with your data to <your-ip>:8000/entries.

To GET your data back (in JSON format) send a request to <your-ip>:8000/entries/<your-pi-id>

Caution! There is no form of authentication when using this. Temperature and humidity aren't really sensible data, but you never know...
