MQ6 MQ 6 MQ-6 Liquefied Petroleum isobutane-propane gas Sensor Module For Arduino. This sensor has high sensitivity and fast response time. The sensor’s output is an analog resistance. The drive circuit is very simple; all you need to do is power the heater coil with 5V, add a load resistance, and connect the output to an ADC. The sensitive material of the MQ-6 gas sensor is SnO2, which with lower conductivity in clean air. When the target combustible gas exists, The sensor’s conductivity is higher along with the gas concentration rising. Please use a simple electro circuit, Convert the change of conductivity to correspond output signal of gas concentration.MQ-6 gas sensor has a high sensitivity to Propane, Butane, and LPG, also a response to Natural gas. The sensor could be used to detect different combustible gas, especially Methane, which is with low cost and suitable for different applications.

YX5300 UART Control Serial MP3 Music Player Module For Arduino/AVR/ARM/PIC. The module is a kind of simple MP3 player device which is based on a high-quality MP3 audio chip—YX5300. It can support 8k Hz~ 48k Hz sampling frequency MP3 and WAV file formats. There is a TF card socket on board, so you can plug the micro SD card that stores audio files. MCU can control the MP3 playback state by sending commands to the module via the UART port, such as switch songs, change the volume and play mode, and so on. You can also debug the module via USB to the UART module. It is compatible with Arduino/AVR/ARM/PIC.

Speak (Voice) Recognition Module V3 -Arduino Compatible is a compact and easy-control speaking recognition board In Pakistan.Speak (Voice) Recognition Module V3 product is a speaker-dependent voice recognition module. It supports up to 80 voice commands in all. Max 7 voice commands could work at the same time. Any sound could be trained as the command. Users need to train the module first before let it recognizing any voice command. This board has 2 controlling ways: Serial Port (full function), General Input Pins (part of a function). General Output Pins on the board could generate several kinds of waves while corresponding voice command was recognized.
