CMPS03 Magnetic Compass Sensor for Fire Extinguisher Robot and It's Interfacing with ATMEGA8535

Eltronicschool. - Beside using UVTron sensor for flame detector, extinguisher robot design also used magnetic compass sensor that used to detect the Earth's magnetic field. And in here we will show you magnetic compass sensor from Devantech Ltd with series CMPS03 Magnetic Compass like in figure 1 below.

Figure 1. CMPS03 Magnetic Compass Sensor


The Fire Extinguisher robot uses sensors CMPS03 Magnetic Compass made from Devantech Ltd. This sensor measures 4 x 4 cm and uses Philips KMZ51 magnetic field sensor is sensitive enough to detect
Earth's magnetic field. This sensor has a 9 pin like in figure 1 above.

The use of this sensor is intended that the robot navigation system be better. Because it can determine the direction of the wind through the this sensor. Compass sensor interfacing with microcontroller using C.0 and C.1 port, the port has a special function as pathways I2C communication, sensor readings should use the path. To know interfacing CMPS03 Magnetic Compass sensor with Microcontroller ATMEGA 8535 circuit schematic show like in figure 2 below.
