obliquez said:I'm using a Honeywell lle sensor. LLE 105000 (Type 5) Mounts on the
inside. I intend to integrate the sensor into the handle of a mug.
It is required for me to include a driver circuit in my design. That's
what my teacher said. I heard that i can purchase a 3-24V circuit board
and get the right components, then connect the sensor and buzzer to it?
As in i get the circuit board and the right transistor and resistors?
Oh my, I know it's supposed to be really simple to understand, but i'm
not a very good student. =(
Thanks you guys for helping me out! =)
Yes the driver will be very simple. But the kind of driver needed
depends on whether your buzzer makes a tone when connected to DC
(contains and internal oscillator) or has to be driven by AC (is just
a transducer). Did you perform the test I described?
If your buzzer makes a tone when connected to a battery, then the
driver is just a single PNP transistor and a few resistors. If it
just clicks, then the driver has to be an oscillator that produces a
wave close to the resonant frequency of the buzzer, but us gated on
when a logic low (negative supply) voltage is applied from the sensor.
