If you are a beginner to ESP32, we recommend reading Getting Started with the ESP32 on Arduino IDE What You Will Learn Getting to know the web server ...

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...

MPU9250 + BMP280 Module Features This IMU module is a small board which all the sensors required for 10 degrees of freedom are placed in. This module communicates with the Arduino or microcontrollers via the I2C interface. Using the existing FreeIMU functions and source code, you can easily use this IMU as an AHRS system in flight controls. You can use this module in VTOLs, model airplanes, UAVS, and also industrial and medical devices. GY-91 Module Pinout This s...

Inductive Proximity Sensor LJ12A3-4-Z/BY Features A proximity sensor is a sensor able to detect the presence of nearby objects. The inductive proximity sensor LJ12A3-4-Z / BY has three pins, two of which are connected to a supply voltage of 6 to 36V. The output pin is PNP and NO (Normally Open). That is, it is normally Low and when it detects an object, it is HIGH. The detection distance is 4 mm and it can only detect metal objects such as copper, aluminum, iron, etc. Note Because the operatio...

APDS-9930 Ambient Light Sensor Features This module consists of ambient light , IR and proximity sensors. The detection distance is up to 100 mm. The APDS-9930 sensor measures the ambient light. This sensor can also detect 0.01 Lux brightness in the dark. It can also be used behind dark glass like a mobile screen. For example, it turns off the touch screen during voice calls when your ear is close to the screen.This sensor can be used to adjust the brightness of mobile backlight and the approp...

TLP281 4-Channel Opto-isolator IC Module Features Sometimes we need to separate the low-voltage section (microcontroller) from the high-voltage one in circuit in order to prevent noise and damage to the microcontroller. This module isolates the low-voltage section from the high-voltage section using TLP281-4 IC. This IC contains 4 LEDs (Light Emitting Diode). 4 high-voltage channels can be controlled by microcontroller using this IC.This module can also be used to turn on and off the servo motor and oth...
