Alcohol Sensor(MQ3) module is useful for gas leakage detection (in home and industry)
Temperature Range: -40°C to 80°C
This voltage detector is designed for electrical testing
is implemented in its true form meaning that the end-around carry can be accom-plished without the need for logic or level inversion
Voltage rating: 12 V
High Quality electric soldering iron (Adjustable 4700 uf Alcohol Sensor(MQ3) module is usefulIntroduction : A soldering iron is a hand tool used to heat solder, usually from an electrical supply at high temperatures above the melting point of the metal alloy. This allows for the solder to flow between the workpieces needing to be joined. Features : Work Voltage: 220V . Power: 60W . Dimensions: 30. 00cm x 9. 00cm x 3. 00cm. Adjustable heat CAUTIONS: When using the soldering iron for the first time, smoke may appear on the tip and stop in a
