Arduino light sensor module for Sensor Shield
Based on LDR (Light Detect Resistor), this Light Sensor Module measures the environment light intensity and input data to Arduino through the analog IO port of Sensor Shield. Great tool for light following robot, gardening system or home alert system.
Building interactive work is as easy as piling bricks, just plug it to our Arduino Sensor Shield with a buckled cable, and make it looks professional and neat.
Plug it and Arduino senses temperature !
Based on thermistor, this Temperature Sensor Module measures the environment temperature and input data to Arduino through the analog IO port of Sensor Shield. Great tool for gardening projects, home alert system etc.

Plug it and Arduino can sense magnet!
The magnetic reed switch module is a wonderful tool for designers who would like to turn a circuit on and off based on proximity. A digital “high” value is given when approached by magnet in around 1 inch (depends on strength of the magnet)

Arduino Buzzer Module for Sensor Shield
This is a small buzzer for the Sensor Shield. It creates different noises based on the different frequency of I/O toggling. All you need to do is to plug in the buzzer module to sensor shield, and tell the function which pin you’d like to use, the frequency you want to hear, and the duration to play that frequency.

Arduino Sensor Shield V4 digital analog module & servos
This is a copy of the original post on Ebay
Arduino Sensor Shield V4.0 allows you to connect to various modules like sensors, servos, relays, buttons, potentiometers……….just plug & play.
Each functional module has buckled port with VCC, GND and Output, which has corresponding port on the Sensor Shield, connected with a plain 2.54mm dual-female cable you may start playing already. Buckled brick cables are like cement for bricks, make the connections easier, secure and more professional looking.
Plug it and Arduino can sense your presence of object by infrared!
The Infrared Reflectance Sensor Module carries a single infrared LED and phototransistor pair in an inexpensive, tiny module that can be mounted almost anywhere and is great for obstacle detection of robot and home alert system. The optimal sensing distance is within 50cm (20 inches).
Building interactive work is as easy as piling bricks, just plug it to our Arduino Sensor Shield with a buckled cable, and make it looks professional and neat.
The Infrared Reflectance Sensor Module simply gives a digital signal when it detects infrared reflection from a person or object, so the code is exactly as the one we would use for a pushbutton. Please be noted that, when reflection is detected, it gives a “low” value.
int ledPin = 13; // choose pin for the LED int inputPin = 2; // choose input pin (for Infrared sensor) int val = 0; // variable for reading the pin status void setup() { pinMode(ledPin, OUTPUT); // declare LED as output pinMode(inputPin, INPUT); // declare Infrared sensor as input } void loop(){ val = digitalRead(inputPin); // read input value if (val == HIGH) { // check if the input is HIGH digitalWrite(ledPin, LOW); // turn LED OFF } else { digitalWrite(ledPin, HIGH); // turn LED ON } }

Ever wanted to control the lights from your home computer?
Or perhaps some other appliance in the house?
This post is a copy of this Arduino Relay on Ebay. I am replicating it here because ended items on Ebay are not indexed by Google, the author’s page is written in Chinese and doesn’t contains the Source code. If you are the author and you are obset with this, please get in touch.
Appliances with high voltage and current can’t be controlled by the Arduino digital IO ports directly, we need a relay to solve this problem. The Arduino Relay module allows Arduino Sensor Shield with digital outputs to control larger loads and devices like AC or DC Motors, electromagnets, solenoids, and incandescent light bulbs.

This is a quick tutorial about sending and receiving SMS from/of the computer with a GSM/GPRS modem and Java.
Requirements
Introduction
It is possible to use a programming language to send Hayes Commands (aka AT commands) through the serial port to a cellphone modem, plugged into a PC . With these commands the cellphone can send SMS.
Continuing in the Anemometer project, I guess I found the cheapest way to send data over the GPRS network.
The SSerial2Mobile project is a library for Arduino, to stablish a serial connection with a mobile phone.
The project web site says that they could connect with a cheap Motorola C168i.
It costs around U$27,00 plus shipping on Ebay.
I bought an used one for U$14,00 (plus U$13,00 of the shipping)
It is pretty cheap compared to the EUR$77,00 GPRS Shield for Arduino from Libelium.
