Arduino Light Sensor | Arduino Tutorial

+

Arduino Light Sensor. Arduino Uno''s pin A0 to A5 can work as the analog input. The analog input pin converts the voltage (between 0v and VCC) into integer values (between 0 and 1023), called ADC value or analog value.. By connecting a pin of the photoresistor to an analog input pin, we can read the analog value from the pin by using analogRead() function, and then we can know the light ...

I Need Sensor that measures the pressure of propane gas in ...

This list of Arduino sensors and modules are in “module” formfactor. This means they already include things like currentlimiting resistors, terminal posts, and potentiometers onboard to help you save time. While this makes creating with your Arduino simple, its not entirely necessary. For example, in lieu of the twocolor LED module, you could use a two color LED, 330 Ohm resistors, and ...

Gas sensor : Various types of gas sensors are used for detection of different gas types. It converts chemical information in the gas into measurable electronic signals such as voltage, current or frequency. These sensors are useful to measure emission levels of gases which are essential to keep them within limits for the safety of human beings.

HCSR04 Ultrasonic Sensor with Arduino Tutorial (5 Examples)

AO (Analog Output) pin gives us an analog signal between the supply value (5V) to 0V. DO (Digital Output) pin gives Digital output of internal comparator circuit. You can connect it to any digital pin on an Arduino or directly to a 5V relay or similar device. GND is a ground connection.. VCC pin supplies power for the sensor. It is recommended to power the sensor with between – 5V.

MQ4 Methane Sensor Circuit Built with an Arduino
