I need to make two physical band reject filters which have ranges of 1-150Hz and 150Hz-300 Hz respectively. Further, sizes of these filters need to be in in between 8-10 cm². Can you please guide me how to make them, or, where I can get sufficient information to make one? I am novice in this...
Thanks for the help all the while!
Having read all this, could you please formulate a step by step procedure on how to install the whole thing. Wherever learning or programming is required, please mention that. After reading all the above posts, I have got a bit confused on which equipments to...
The screens are intended to last around 6 months or so. The wearing is so less that it is purposeful to check their status weekly or twice in every week. Also, since it is desired to embedd a small battery to supply the power, please suggest which battery should be used?
Further, the link to the...
Yeah! Thanks! Looks like it can be proceeded with.
One thing though. Please suggest the type of receiver which have to be used to read those pulses. Also, there are like 20 different screens in an arrangement. What should be done to uniquely give each transmitter an id or something and then read...
Thanks for the help!
I was wondering if we can have a system where the transmitter remains "on" while current is flowing. Now, if we wish to check its status, it will reply back with affirmative when it is "on" or working. If current is cut out, then, we won't be getting any reply from...
Yes, that is right. I want to embedd a simple circuit around the screen with detector and send the information of current's presence or absence 20 metres away.

See, installing an alarm is not an option because...
Ok, its fine to embedd a diode. But how do, I get to know if current is flowing or not? I mean, if current stops flowing after wire gets cut down by wearing, how would i be knowing?
I visualized the system like this:
If the current is flowing, that "hardware" is transmitting that information to...
The situation is like this:
As you can see in the attached images, there are screens having numerous apertures. In industries, these screens are used for mineral processing and are often kept in stacks of say, 20 ft by 8 ft. Each screen itself is around say 1.5 ft* 1.5 ft. Now, in due course of...
For the above questions,
a) No, I don't have idea of how much current would be flowing but it shud be in orders of m-A as per demand of the problem
b) Any tampering could be done as long as it helps in sensing if current is flowing or not and then transmitting it
c) No, this is not for...
Hi,
I am a third year undergrad Mechanical Engineer asked to design a circuit where I can detect absence or presence of current and transmit that information wirelessly to some system where one can find see if that circuit has current or not. Sorry if I have posted in wrong thread.
You can...
