DTMF Enabled SIM900 GPRS/GSM Shield

Overview

This shield provides GPRS/GSM service to Arduino. With this shield attached (together with a SIM card), Arduino could join its local mobile service provider’s cellphone network and start communication via SMS, Voice, DTMF, and GPRS service.

This shield connects to Arduino with long-wire headers, which keeps the pin layout intact and allows another shield to be stacked on top.

PoE Enbled Ethernet/TF Card Shield

Overview

This Ethernet shield gives Arduino TCP/IP network access capability. Thanks to the onboard W5100 chip, TCP/IP stacks has already been implemented on this chip. Benefit from the integrated protocol stack, Arduino only need to operate on sockets, which dramatically reduces the complexity of implement TCP/IP connectivity and saves a lot of RAM and ROM space for user application.

Breakout Shield for Arduino UNO or AIRduino

Overview

This breakout shield was designed for Arduino UNO R3. It has all 14 digital I/Os, all 6 analog inputs broke out. Additionally, it has I2C, SPI, UART and two analog input interlock connectors broke out. There are six LEDs on the board, which could be used to indicate the status of the I2C, SPI, and UART activities. All the LEDs are buffered by transistors, drawing insignificant current from I2C, SPI, and UART lines, so the LEDs will not affect the state of those lines. The two additional input interlock connectors, denoted as A and B, could be connected to A0 to A5 by jumpers.

I2C DS1307 RTC/Real-Time Clock Module

Overview

This module has a DS1307, a battery socket and three pull-up resistors on the PCB. It uses I2C protocol to communicate with external I2C master (Arduino board, PIC, AVR, etc.). The SQW/OUT pin of DS1307 is broke out via a 3-pin interlock connecter. A 4-pin connector eases the wiring to an Arduino Sensor Shield. The three pull-up resistors are connected to SDA, SCL, and SQW respectively, and they are clearly noted on the silkscreen of the PCB. User could take them off board if those pull-up resistors have already been implemented somewhere else off the module.

MQ-8 Hydrogen/H2 Sensor Module

Overview

This sensor module has an MQ-8 as the sensor component and has a protection resistor and an adjustable resistor on-board. The MQ-8 gas sensor is highly sensitive hydrogen and less sensitive to alcohol, and cooking fume. It could be used in gas leakage detecting equipments in family and industry. The resistance of the sensitive component changes as the concentration of the target gas changes.

MQ-6 LPG LNG Gas Sensor Module

Overview

This sensor module utilizes an MQ-6 as the sensitive component and has a protection resistor and an adjustable resistor on board. The MQ-6 gas sensor is highly sensitive to LPG, iso-butane, propane and less sensitive to alcohol, cooking fume and cigarette smoke. It could be used in gas leakage detecting equipments in family and industry. The resistance of the sensitive component changes as the concentration of the target gas changes.

3.3V/5V Dual Output Breadboard Power Supply

Overview

This breadboard power supply features in a dual-channel output configuration. The input voltage can range from 6.5V to 15V. The on-board barrel connector allows the most common AC/DC adaptor (AC/DC wall-mount plug) to be used as the power source. This board features in a “plug and play” design. The board fits directly onto the most breadboards (MB-102) so that no wiring is needed for powering up the breadboard power rails.

MQ-2 Smoke/LPG/CO Gas Sensor Module

Overview

This sensor module utilizes an MQ-2 as the sensitive component and has a protection resistor and an adjustable resistor on board. The MQ-2 gas sensor is sensitive to LPG, i-butane, propane, methane, alcohol, Hydrogen and smoke. It could be used in gas leakage detecting equipments in family and industry. The resistance of the sensitive component changes as the concentration of the target gas changes.

MG-811 CO2 Sensor Module

Overview

This sensor module has an MG-811 onboard as the sensor component. There is an onboard signal conditioning circuit for amplifying output signal and an onboard heating circuit for heating the sensor. The MG-811 is highly sensitive to CO2 and less sensitive to alcohol and CO. It could be used in air quality control, ferment process, in-door air monitoring application. The output voltage of the module falls as the concentration of the CO2 increases.
