Arduino Data Logger Shield Features The Arduino data logger shield can be used to make a connection between an Arduino and an SD card. In fact, this module can be used to store Arduino data. It is very suitable for storing data when the Arduino power supply suddenly shuts down. This module also has a DS1307 module as RTC for keeping time and date. The communication protocol for RTC is I2C and for SD card is SPI. Arduino Data Logger Shield Pinout This module is pla...

What Is Reed Switch? The Reed Switch is a magnetic switch that has two (on and off) switching modes, like a normal switch. The two pins are connected to each other by being in a magnetic field (for example, close to the magnet) and are disconnected by leaving that field. These switches are used in open/close door detection sensors, seat belt sensors, collision detection sensors, etc. Tip Some magnetic switches are Normally Close. That is, when they are not in a magnetic field, the two pins are co...

GY-271 Compass Module Features Magnetic current and field have directly relation with each other. When current flows in a wire (electrons start travelling in one direction), a magnetic field is created. The main idea of compass sensors is based on this relationship. The direction of the earth's magnetic field affects the flow of electrons in the sensor. By measuring these changes in current, the sensor will be able to detect direction.The GY-271 module uses the QMC5883L chip to detect magnetic fields an...

Buzzer Features A buzzer is a device used to produce sound. There are two types of buzzer: active and passive. In the active model, buzzer starts playing sound only if connected to a power supply, but in the passive model, we need to send a pulse from the microcontroller to play sounds. The supply voltage of the buzzer is 3 volts, 5 volts and 12 volts. You can download the passive buzzer datasheet here. [wpdm_package id='16469'] Passive Buzzer Module Pinout Buzzer has 2 pins: DATA and GND but t...

GY-511 Compass Module Features Magnetic current and field are directly related to each other. When current flows in a wire (electrons start travelling in one direction), a magnetic field is created. The main idea of ​​compass sensors is based on this relationship. The direction of the earth's magnetic field affects the flow of electrons in the sensor. By measuring these changes in current, the sensor will be able to detect directions. The GY-511 module uses the LSM303DLHC chip to detect and direct magn...

KY-037 Sound Sensor Module Features KY-037 module consists of a capacitive microphone and an amplifier circuit. The output of this module is both analog and digital. You can download the datasheet of this module here.[wpdm_package id='16686'] KY-037 Sound Module Pinout This module has 4 pins, 2 of them are for power supply. Pin 1: The analog output.

ACS712 Current Module Features ACS712 chip is used to measuer DC/AC current based on the Hall effect. This chip is produced in 3 models with different maximum currents. Different models and output sensitivity of each model are shown in the table below: Sensor sensitivity means that, for example, if you use 5 amp model, as input current increase 1 amp, the output voltage of the sensor increases about 185 mV. Note When input is not connected to something and th...

DHT11 Sensor Features The DHT11 is a digital temperature and humidity sensor. This sensor is able to measure the humidity in the range of 20% to 80% with an accuracy of 5%. It can also measure the temperature in the range of 0 to 50 degrees Celsius with an accuracy of 2 degrees. Note The sampling frequency of this sensor is 1Hz. As a result, there must be at least one second between every readings of the sensor, otherwise the reading values will be incorrect. ...

FC-04 Sound Sensor Features This module consists of a capacitive microphone and an amplifier circuit. The output of this module is analog. This module can be used to measure ambient noise. You can adjust the accuracy of the sensor by using a variable resistor on the device. FC-04 Sound Module Pinout FC-04 module has 3 pins: VCC: Module power supply: 5 V GND: Ground OUT: Module output (Analog) You can see the pinout in the following image. Required Materials Hardware C...
