Abstract: Embedded systems are the most widespread technologies today. These technologies include hardware and software. We may meet them from simple household appliances such as the washing machine and microwave oven to more sophisticated appliances such as aircraft, medical appliances, and automobiles not to mention mobile phones, TVs and radio receivers, leisure gadgets, etc. This project thesis goal is the measurement and the monitoring of the discharge of the battery used as the energy supplier in a quadrocopter. Its particularity is that the battery monitoring is done remotely through a radio link in embedded systems. To do this, the discharge of the battery will be measured by a hardware called the charge measurer which will measure how much charge flows from the battery. The status of the battery will be transmitted to the ground by a radio transmitter device and it will be received by a radio receiver module. The monitoring of the battery status will be carried out by software implemented in IAR Embedded systems. The Monitoring of the status of the battery will happen from the ground when the quadrocopter flies. When the quadrocopter flies the user will know how fast the energy is consumed and when the flight is over, the user will know how much energy was consumed. This can help the user to monitor the energy consumption and to know when it is possible to land the appliance safely. To perform this project several important tasks will be done such as:   -Conception and the design of the current measurer circuitry -Design of the printed circuit -Laboratory testing -Simulation of the electronic circuit with the help of some tools like Orcad and PSpice -Mounting of the electronic components on the printed circuit board -Design of the software -Writing the C code in the platform IAR Embedded system
