Arduino IR Receiver 3 Pin 38khz Receiver In Pakistan

MQ4 MQ 4 MQ-4 High Sensitivity Gas Methane (CNG) Detector Sensor Module For Arduino is a simple to use MQ-4 High Sensitivity Gas Methane (CNG) Detector Sensor Module For Arduino which can sense the presence of Compressed Natural Gas(CNG), methane(CH4), etc in the air. The module uses our MQ-4 sensor. It simplifies the interface to the odd pin spacing of the sensor and provides the interface through standard 4 x 0.1″ header pins. It provides an analog output corresponding to the concentration of the gases in the air and an easy-to-use digital output. The onboard potentiometer can be used to set the maximum gas concentration beyond which the digital output gets triggered. Just power the module with 5V set the threshold and you can start getting the gas concentration of the air around the sensor! An onboard LED signals the presence of any gas. The digital output can be easily interfaced to microcontrollers and other circuits. The analog output can be hooked up to an ADC of a microcontroller to get a wide range of sensor readings. This is a simple-to-use compressed natural gas (CNG) sensor, suitable for sensing natural gas (composed of mostly Methane [CH4]) concentrations in the air. The MQ-4 can detect natural gas concentrations anywhere from 200 to 10000ppm.

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.
