This alcohol gas sensor detects the concentration of alcohol gas in the air and ouputs its reading as an analog voltage. The concentration sensing range of 0.04 mg/L to 4 mg/L is suitable for breathalysers (the legal limit of breath alcohol concentration, or BrAC, in most US states is 0.08 grams per 210 liters, or 0.38 mg/L). The sensor can operate at temperatures from -10 to 50 Degree C and consumes less than 150 mA at 5 V.

This semiconductor gas sensor detects the presence of methane (CNG) gas at concentrations from 300 ppm to 10,000 ppm, a range suitable for detecting gas leaks. The sensor s simple analog voltage interface requires only one analog input pin from your microcontroller.
The GP2Y0A41SK0F Sharp analog distance sensor features a detection range of 1.5 to 12 (4 cm to 30 cm). The shorter range gives you higher resolution measurements, and the lower minimum detection distance makes this sensor great for detecting very close objects. The distance is indicated by an analog voltage, making this sensor very easy to use.
