HC-06 RF Wireless Bluetooth Transceiver Slave Module RS232 / TTL to UART converter and adapter. This module is an Upgrade from the older HC-05 and has better stable Firmware. Features: Bluetooth Serial Transceiver Module with backboard. This module includes key interface and state interface compared with Smart Bluetooth Module Baseboard. The Bluetooth Module Baseboard can be compatible with slave mode. Works for Bluetooth TTL transceiver module which allows your target device to both senders receive the TTL data. The key interface on the baseboard is the master mode button and can be controlled by high level from external MCU, and then this module will search again automatically. Built in antenna Bluetooth version: V2.0 EDR

The TCS230 programmable color light-to-frequency converter combines configurable silicon photodiodes and a current-to-frequency converter on single monolithic CMOS integrated circuit. The output is a square wave (50% duty cycle) with frequency directly proportional to light intensity (irradiance). The full-scale output frequency can be scaled by one of three preset values via two control input pins. Digital inputs and digital output allow direct interface to a microcontroller or other logic circuitry. Output enable (OE) places the output in the high-impedance state for multiple-unit sharing of a microcontroller input line.

The 8 channel 12V relay module provides 8 optically isolated inputs that accept a wide range of voltage. This is a great way to switch on or off AC or DC loads using your Arduino. The relays are single-pole double-throw (SPDT) and are rated for 10A @ 250VAC. The ground for the relay coils is separate from the ground for the input signals. This, along with the optical isolation, provides a total galvanic isolation between the input and output. The two grounds could be joined together if desired with the included jumper. The relay coils run on 12VDC, and the module has screw-terminal blocks for sturdy and reusable attachments for the external load. The signal and power inputs run through the male single-row header.

A simple flex sensor 2.2" in length. As the sensor is flexed, the resistance across the sensor increases. The resistance of the flex sensor changes when the metal pads are on the outside of the bend (text on inside of bend). Connector is 0.1" spaced and bread board friendly. Check datasheet for full specifications.

A simple flex sensor 4.5" in length. As the sensor is flexed, the resistance across the sensor increases. The resistance of the flex sensor changes when the metal pads are on the outside of the bend (text on inside of bend). Connector is 0.1" spaced and bread board friendly. Check datasheet for full specifications.

The MQ series of gas sensors use a small heater inside with an electro-chemical sensor. They are sensitive for a range of gasses and are used indoors at room temperature. The output is an analog signal and can be read with an analog input of the Arduino. The MQ-2 Gas Sensor module is useful for gas leakage detecting in home and industry. It can detect LPG, i-butane, propane, methane ,alcohol, hydrogen and smoke.

This module is made using Alcohol Gas Sensor MQ3. It is a low cost semiconductor sensor which can detect the presence of alcohol gases at concentrations from 0.05 mg/L to 10 mg/L. The sensitive material used for this sensor is SnO2, whose conductivity is lower in clean air. It’s conductivity increases as the concentration of alcohol gases increases. It has high sensitivity to alcohol and has a good resistance to disturbances due to smoke, vapor and gasoline. This module provides both digital and analog outputs. MQ3 alcohol sensor module can be easily interfaced with Microcontrollers, Arduino Boards, Raspberry Pi etc.

Gas Sensor(MQ5) module is useful for gas leakage detection (in home and industry). It is suitable for detecting H2, LPG, CH4, CO, Alcohol. Due to its high sensitivity and fast response time, measurements can be taken as soon as possible. The sensitivity of the sensor can be adjusted by using the potentiometer.
-
MQ 6 Gas sensor is used as LPG, Butane and Propane Sensor to generate alarm when there is leakage of these gases from the source. MQ6 is a highly sensitive gas sensor to petroleum based gases but less sensitive to Alcohol and Carbon di oxide. This simple sensor can be installed in the kitchen to give warning alarm if there is leakage of LPG.

This is the XBee XB24-Z7WIT-004 module from Digi. Series 2 improves on the power output and data protocol. Series 2 modules allow you to create complex mesh networks based on the XBee ZB ZigBee mesh firmware. These modules allow a very reliable and simple communication between microcontrollers, computers, systems, really anything with a serial port! Point to point and multi-point networks are supported. These are essentially the same hardware as the older Series 2.5, but have updated firmware. They will work with Series 2.5 modules if you update the firmware through X-CTU.

This is the XBee XBP24-BZ7WIT-004 module from Digi. The new Series 2B improves upon the power output and data protocol of the Pro Series2. Series 2B modules allow you to create complex mesh networks based on the XBee ZB ZigBee mesh firmware. These modules allow a very reliable and simple communication between microcontrollers, computers, systems, really anything with a serial port! Point to point and multi-point networks are supported. Series 2B modules use a different hardware configuration from the earlier models and while they will communicate with Series 2 XBee modules, they are not compatible with the outdated Series 2.5 Modules.
