10x Linear Potentiometers 2k OHM kΩ

Ideal to power your Arduino board through the power input.
9v Battery Adapter Connector 6F22 with Cable features:

High sensitivity to Ammonia (NH3), Nitrogen oxides (NOx), Alcohol, Sulphides, Benzene (C6H6), CO2, smoke and other harmful gases.  The MQ-135 sensor is to sensible for other gasses in the air so that is not possible to get good values for CO2 from it.
MQ-135 Air Quality Sensor features:
- Main chip: MQ-135 natural gas sensor and comparator LM393
- Working voltage: 5V
- Current: 150mA
- Digital output: TTL 0/1
- Analog output: analog voltage sensing value
- Quick response features:
- Detection concentration:
   10ppm - 300ppm NH3
   10ppm - 1000ppm Benzene
   10ppm - 300ppm Alcohol
- Adjustable sensitivity with the potentiometer
- Size: 32mm x 20mmx 18mm

Prototype Breadboard Protoboard 840 points Arduino features:
- 840 Connections
- Linkable with other Boards
- Base with adhesive to attach it to the work surface
- Measures 165x55x8mm

It consists of three principles of induction of primary colors, if you know the composition of all types of color values, you can know the color of the test object.
For TCS230, a color filter is chosen, only a certain primary pass is allowed, it is stopped by another color. For example, when choosing a red filter, the incident light can only be stopped in red, blue and green, so you can get the intensity of the red beam of light.
For the same reason, the choice of other filters, can obtain the intensity of blue light and green light.
Through these three values, the color of the light can be projected onto a TCS230 sensor. Color Recognition Sensor GY-31 TCS230 TCS3200 features:
- Operating voltage: 3 - 5 VDC
- Model GY-91
- Chip TCS230 TCS3200
