My first project – data acquisition system

Project Description

This project is Data-acquisition system using Arduino or Raspberry PI.  It collects sensor data and transmit which with various network communication methods such as ethernet, RF and USB; the collected data is stored in a database server.

This example demonstrates how a Gas Sensor is used and the sensor data is sent to a receiver.

Receiver

Link : http://domoticsduino.blogspot.kr/2015/08/data-acquisition-receiver.html

It’s made up of an Arduino Uno Board, with the ethernet shield to get network access and the wireless RF433 receiver.
For direct transmission of sensor data, a wireless receiver is used while ethernet is used to send data to a WEB/APP server.

HARDWARE

Schema(approx)

PIN 2 OUTPUT for RF status led (RED), reporting wireless activity;
PIN 3 OUTPUT for ETH status led (GREEN), reporting ethernet activity;
PIN 5V to power up wireless received and led;
PIN GND linked to wireless receiver GND pin;
PIN 7 INPUT to receive wireless data;

The Ethernet shield is linked to Arduino UNO; all the system is powered up by external 5V.

SOFTWARE

– wireless receiver setup using RadioHead library;
– ethernet shield setup using standard Ethernet library; it this case we use a static IP (but you can use DHCP if your network provides it);

HARDWARE

PIN 11: push-button
PIN A1: analogue pin linked to GAS sensor
PIN 9: wireless data transmission
PIN 12: red led for wireless activity indication
PIN 8: green led for data acquisition activity
PIN 3, 5 and 6: RGB led for showing system status
– off: normal values;
– yellow: an out of tolerance value under the danger threshold;
– rosso: an out of tolerance value over the danger threshold;
