Sensors and control
Closed - This job posting has been filled and work has been completed.
I am working on a project designing a system consisting of 2 motion sensors, one for detection of movement and the other for the detection of presence.The software am using to design the system is Proteus and that is what I prefer. The system also consists of a LDR which will be designed to detect day light in order to turn on a light. The major components of the lighting system are: 2 motion sensors, one for the detection of movement and the other for the detection of presence, an LDR, relay circuit, PIC16F627A, and a light bulb operating on 240 volt.
The lighting system will operate in the following manner. When light reflects on the LDR the light is turned ON. If there is a motion or presence of a person the light will stay ON otherwise it will turn OFF. This will be done in a PIC micro controller where there will be a constant scan loop of the system to verify if any of the activities are present. I will provide the code for this but I have only programmed it for one motion sensor and will need you to add the code for the second motion sensor. For this system I will need the circuit design and the simulations of the voltage and current waveform.
Rechargeable battery system
This system will detect and charge all the batteries in the lighting system and the temperature control system when they are low. For this system I will need the circuit designed, simulation of the voltage and current waveform, and a calculation of how much energy it uses to recharge the batteries over a certain period of time.
Temperature control system
This system will detect the temperature and turn on the DC moto fan at any temperature above 25 degrees to cool down the temperature of the system. This system will be separate. In this system I will also need the design and simulation of voltage and current wave form.
I have already designed the system but I am having issues with simulations. I will provide the pictures of the designed system so you can use it as a point of reference.I will also provide the C programming language code for the lighting system if you needed for simulations. I have a very tight deadline and I apologies for the short notice. I will need this to be completed by latest this friday 15 August 2014 for submission to my client.
