Overview Thousands of cars are being stolen every day around the globe. So it is really important to protect and secure your car. In this tutorial we will use the SIM808 module to build a GPS car tracker. If you are not willing to use a GPS read this article to find out how to detect location by GSM modules: (Using GSM with Arduino as an alternative for GPS). What You Will Learn Get to know with the concept of GPS Get to know with the sim808 module Build a GPS car tr...

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...

AP3216 Sensor Features The AP3216C is an integrated ALS & PS module that includes a digital ambient light sensor [ALS], a proximity sensor [PS], and an IR LED in a single package.
