This capacitive touch sensor module uses the TTP229 integrated circuit, making it easy to add capacitive touch input to your project. It features 16 sensitive touch pads that make an ideal replacement for the old fashioned keypads.
Specifications:
-On-board 16-key TTP229 capacitive touch sensor IC -On-board power indicator LED -Working Voltage Range: 2.4 V to 5.5 V -Configurable output mode -PCB Size: 49.3 x 64.5 mm -
Sensitive material of MQ-4 gas sensor is SnO2, which with lower conductivity in clean air. When the target combustible gas exist the sensors conductivity increases higher along with the gas concentration rising. MQ-4 gas sensor has high sensitivity to Natural gas, Methane and could be used to detect both Methane and Propane. The sensor could be used to detect different combustible gas especially Methane, its low cost and suitable for different application. Features: -High sensitivity to Combustible gas in wide range. -High sensitivity to Natural gas Methane, Coal gas, CO etc gas. -Fast response. -Wide detection range. -Stable performance, long life, low cost. -Simple drive circuit.

Features :
- Ready to plug & play.
- It can connect to various modules like sensors, servos, relays, buttons, potentiometers
- Each functional module has buckled port with VCC, GND and Output, which has corresponding port on the Sensor Shield, connected with a plain 2.54mm dual-female cable you may start playing already. Buckled brick cables are like cement for bricks, make the connections easier, secure and more professional looking.

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.

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.
