MQ-3 Alcohol Sensor Module Ethanol Breathalyzer

S0009

Ethanol alcohol sensor module.
MQ gas sensor uses a small indoor heater with an electrochemical sensor.
When the alcohol molecules in the air comply with the electrode the ethanol "changes" into acetic acid and then more current is produced.
MQ-3 Alcohol Sensor Module Ethanol Breathalyzer features:
- Main chip: alcohol sensor MQ-3 and comparator LM393
- Working voltage: 5V
- Current: 150mA
- Digital output: TTL 0/1
- Analog output: analog voltage sensing value
- Detection concentration:
- 0.05mg/L - 10mg/L
- Quick response features:
- Adjustable sensitivity with the potentiometer
- Size: 32mm x 20mmx 18mm

Color Recognition Sensor GY-31 TCS230 TCS3200

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

Arduino Nano Every

Arduino has decided to further develop its catchy Nano project in the direction of more power. Nano Every is the simplest of the new series as it doesn´t include any sensors nor connectivity solution, however still significantly more powerful than standard Nano (50% more program memory and 2 times more RAM). Above characteristics make it perfect for projects of small devices with more advanced functionalities, such as audio processing or robotics.
