MP3-TF-16P MP3 SD Card Module with Serial Port
MP3-TF-16P MP3 Disk TF Card Module Serial Port is a compact and inexpensive MP3 module that can be connected directly to the speaker. Module with battery power supply, speaker, the keypad can be used alone, or through the serial port control, as the Arduino UNO or any microcontroller with a serial port module. While the software supports TF card driver to support FAT16, FAT32 file system. It can be done by simple serial command plays the specified music, as well as how to play music and other functions, without tedious low-level, easy to use, stable and reliable. The module itself perfectly integrated hardware decode MP3, WAV, WMA.
MPR121 Breakout V12 Capacitive Touch Sensor Controller Module I2C keyboard
This MPR121 is a capacitive touch sensor controller driven by an I2C interface. The chip can control up to twelve individual electrodes, as well as a simulated thirteenth electrode The MPR121 also features eight LED driving pins, when these pins are not configured as electrodes, they may be used to drive LEDs. There are four jumpers on the bottom of the board, all of which are set (closed) by default. An address jumper ties the ADD pin to the ground, meaning the default I2C address of the chip will be 0x5A. If you need to change the address of the chip (by shorting ADD to a different pin), make sure you open the jumper first. Jumpers also connect SDA, SCL, and the interrupt pin to 10k pull-up resistors. If you do not require the pull-up resistors you can open the jumpers by cutting the trace connecting them.
MPU9250 9-Axis Gyro Accelerometer Module
MPU9250 9-Axis Attitude Gyro Accelerator Magnetometer Sensor Module features the MPU-9250, which is a multi-chip module (MCM) consisting of two dies integrated into a single QFN package. One die houses the 3-Axis accelerometer and gyroscope. The other die houses the AK8963 3-Axis magnetometer. Hence, the MPU-9250 is a 9-axis Motion Tracking device that combines a 3-axis accelerometer, gyroscope and magnetometer, and a Digital Motion Processor (DMP). It is based on I2C Address, Address: 0x68 by default, 0x69 if AD0 is pulled high.
MQ-131 Ozone Gas Detector Sensor Module
The sensitive material of the MQ131 gas sensor is O3 SnO2, which with lower conductivity in clean air. When Ozone 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. MQ131 gas sensor has a high sensitivity to Ozone, also sensitive to O3 CL2, NO2, etc.
MQ-136-Hydrogen Sulfide Gas Sensor
MQ-137 Ammonia Gas NH3 Sensor Module
The MQ137 sensor is a gas sensor module is specially designed to detect and sense gases like ammonia (NH3) and carbon monoxide (CO). The MQ137 gas sensor module comes with digital pins that can be connected to a microcontroller like Arduino boards and come in handy when you are only trying to detect one particular gas.
- Wide detecting scope
- Fast response (less than 1s)
- High sensitivity( 3%)
- the circuit voltage: DC5V
- Stable and long life
- Operating Voltage is +5V
- Detect/Measure NH3, Ammonia
MQ-2 Smoke LPG Butane Hydrogen Gas Sensor Detector Module
MQ-4 High Sensitivity Gas Methane CNG Detector Sensor Module
This is a simple to use MQ-4 High Sensitivity Gas Methane (CNG) Detector Sensor Module 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.
