MQ-6 LPG Gas Sensor Module
This is a simple-to-use liquefied petroleum gas (LPG) sensor, suitable for sensing LPG (composed of mostly propane and butane) concentrations in the air. The MQ-6 can detect gas concentrations anywhere from 300 to 10000ppm. This sensor has a 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.

TTP 223B (Touch Thumb Sensor Module)
Product description:
This is a simple touch sensor module. You can use it to replace a traditional push button. Using the TTP223 touch detector IC It measures the capacitance of a metallic pad. It can detect the change in capacitance when a finger is near it. This is the same technology used in the iPhone touch screen.This little sensor can "feel" people and metal touch and feedback a high/low voltage level. Even isolated by some cloth and paper, it still can feel the touch. And the sensitivity well decrease as isolation get thick.
