Optimum Energy Management System
The project is designed to monitor the number of persons entering as well as exiting a room. Electrical loads are switched ON as the first person enters and switches OFF when the last person leaves. IR sensors used in combination with microcontroller to monitor all the operations. This helps in saving lot of energy.
There are two pair sensors, each kept at certain distance from the other. One pair of sensor consists of a transmitter and a receiver, kept exactly opposite to each other. The transmitting part emits modulated IR light which is received at the receiver end and fed to a microcontroller of 8051 family.
When a person enters the room then microcontroller senses it (with the help of IR sensors) and increments the count and displays it on 7 segment displays and also switches ON the load. In the same way when a person exits the room, the count gets decremented. When the last person exits from the room, the lamp is switched OFF. The load operation is handled by a relay interfaced to the microcontroller.
Further the project can be enhanced by using timer arrangement in the project so that if the load switching doesn’t take place for some reason as desired, then timer would complete the task after prefixed time.

"I live in Hyderabad, a place that is known for engineering colleges. Went with frnd and bought a set from Ameerpet(tht hs rdymade stuff like this) and it failed just b4 viva. Thats when we got this thx to a senior who is sorta like a geek.. and let me tell u.. Its one reason why me and my frnds got thru the final sem. Works great and is useful too later.. "Ravi Teja

"A must-buy. It helped me practice in real time and learn how to make a project by looking at an actual workable unit. (fyi - you get a fully built unit and another full set of components to build another by yourself) so it was great value for us. We shared the costs by 3 (our team for the project) but i got to keep my unit as the other two kept the original. Showed it for my on-campus and got thru too becuase it not just looked neat and profesionally bt worked great later. (still have it in my room, now working with GE in Bangalore) "Anusha

"We have used it for our institution - it is available in lab and has been good for explaining various models in live during class. Strongly suggest every college dept to have it for labs as it is working well - even with regular use at lab for more than 1 year. Note:We got the unit complementarity before launch in 2014 and have later purchased few batches. The team behind it is professional and know what electronics students need and i am writing this review on their request on 13/05/2016"Mr. Ramesh Kumar Jha

Q: How does the counting of persons happen?
A: Using bidirectional (entry / exit) detection by IR and TSOP, counting of persons takes place.
Q: Which microcontroller is used in this project?
A: A 40 pin 8051 microcontroller is used in this project.
Q: Is it possible to increase the maximum count limit?
A: Yes, on demand, the maximum count limit can be increased.
Q: What is TSOP?
A: TSOP is an IC which acts as a receiver for receiving IR signal.
Q: What is IR emitting device?
A: Device emitting Infra red rays, which cannot be seen by human eyes is a IR emitting device.
Q: What is the distance range supported for IR-TSOP?
A: Distance range supported for IR-TSOP is 2 feet
Q: Can this project be implemented in industries?
A: Yes, it can be used to sense objects/products in an industry.
Q: Is it possible touse this system as a security system, and can the lamp be replaced with any alarm?
A: Yes, it can be used as a security system and the lamp can be replaced with an alarm.
Q: Is this system useful at offices or residences?
A: Yes, this system is useful at offices or residences.
Q: What is the formula for calculating smoothing capacitor value?
A: There is some approximated formula .Peak to peak ripple voltage = Load current in amps / (2*line frequency in hertz *capacitance in farads). But as rule of thumb for 1 A current 1000uF is best. Thus it is load dependent.
Q: What to do when the lamp fails and what is the maximum lamp rating that can be used?
A: If the lamp fails one can use any lamp or bulb which is used in homes up to 100W. We suggest you to go for low watt bulbs.
