Q: Is it possible to replace lamps with any home loads like T.V., Fridge etc.?
A: Yes, lamps can be replaced by other loads, but only those with power rating till 200W.
Q: At what distance can I operate the loads with IR TV remote?
A: One can operate loads with IR remote till a distance of 15 feet approximately.
Q: Which microcontroller is used in this project?
A: The microcontroller used in this project is a 20 pin IC from 8051 family
Q: What is TSOP?
A: TSOP (Thin Small Outline Package) is an IC package, which acts like a receiver for receiving the coded IR signals.
Q: What is IR emitting device?
A: It is a device emitting rays in infrared band, which cannot be seen by human eyes.
Q: What is the distance range it supports for IR-TSOP?
A: About 2 feet, distance range is supported for IR-TSOP.
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.
