BreadBoard

Solderless Large BreadboardA breadboard (or protoboard) is usually a construction base for prototyping of electronics. The term "breadboard" is commonly used to refer to a solderless breadboard (plugboard). Because the solderless breadboard for electronics does not require soldering, it is reusable. This makes it easy to use for creating temporary...

Description
The MQ series of gas sensors use a small heater inside with an electrochemical sensor. They are sensitive to a range of gasses and are used indoors at room temperature. The output is an analog signal and can be read with an analog input of the Arduino.
 
1. Analog output voltage with concentration, the higher concentration, the higher voltage.
2. Has long service life and reliable stability 
3. Rapid response recovery features
 
Specification:
 
Input voltage: DC5V 
Power consumption (current) : 150 mA 
AO output: 0.1-0.3 V (pollution-free)
Highest concentration of voltage: Approx 4 V 
Detection range of alcohol: detection range of 10 ~ 1000 PPM
 
Connection mode: 
 
1. VCC: Positive (5 v) 
2. GND: Connect power negative 
3. DO: TTL switch signal output
4. AO: Analog signal output

SparkFun ToF Range Finder Sensor - VL6180

Description: This is the SparkFun “Time-of-Flight”  Range Finder, a sensor board for the VL6180  distance sensor. Unlike most distance sensors  that rely on reflected light intensity or reflected  angles to determine range, the VL6180 uses a  precise clock to measure the time it takes light  to bounce back from a surface.
