Hi guys, I've been using your forums for quite a while to help reinforce my physics principles, and only just made my account. I wanted to know if there were any electrical engineers that would be willing to assist me with some guidance in a small design challenge.
Here are the goals
Design a circuit with no moving parts (i.e., no switches) that
(1) will effectively monitor the integrity of the thin wire sensor, and
(2) it will set off the buzzer if the window is breached (and hence the thin wire as well.)2. Relevant Constraints
12 1.5V AAA batteries
1000 1Ω resistors
2900 Hz piezoelectric buzzer
- draws 15 mA at 6 V
- Minimum(Voltage) 6V and maximum 28V to operate buzzer
I already have a rough model, but it does not provide the required voltage when simulated in Pspice... I am pretty sure my methodology is completely wrong
Ideally, the least parts should be used.
If anyone is willing to help me with some guidance for this minor project it would be greatly appreciated! PM me for more details if interested
