This is best done using the BMP180, which is controlled via I2C on the Raspberry Pi. In addition to the air pressure, the temperature can be read out as well as the altitude. However, the last value is not very accurate. If you need the height, you should read the values with a GPS receiver. Price: about $5-6 / ca. £3-4. Moisture Sensor. See the tutorial.

MQ-2 Semiconductor Sensor for Combustible Gas

The sensors performance will be changed badly if sensors be sprayed polluted by alkali metals salt especially brine, or be exposed to halogen such as fluorin. Touch water Sensitivity of the sensors will be reduced when spattered or dipped in water. Freezing Do avoid icing on sensor’surface, otherwise sensor would lose sensitivity.

Presenting MQ sensors: low-cost gas and pollution ...

· In theory, we should be able to generate 5 V pulses with a 40% duty-cycle, by means of such a solution. The sensors of the MQ series are mainly used in closed environments that anyway should not be particularly cold or warm, given that the heating filament’s temperature is kept quite constant by its resistance variation (it grows when the temperature grows, and vice versa) but it is not ...

MQ2 Gas Sensor - Working Principle & Its Applications

MQ2 gas sensor is an electronic sensor used for sensing the concentration of gases in the air such as LPG, propane, methane, hydrogen, alcohol, smoke and carbon monoxide. MQ2 gas sensor is also known as chemiresistor. It contains a sensing material whose resistance changes when it comes in contact with the gas. This change in the value of resistance is used for the detection of gas. MQ2 Gas ...
