Do you have a big water tank in your
house, where you mostly use it to fill the tap water? If you did, then
you must be very pissed off, when you forgot to turn off the tap and
the water spill out from the water tank occasionally…
Well, don’t mad about yourself, as
you’ve a better solution for it! In this case, you can build a highly
sensitive water level sensor. For your information, water level sensor
is being used to detect liquid level, as the liquid to be measured
either can be inside a container/water tank or can be in its natural
form.
Basically, it has two different
measurements: Continuous or point values. Continuous level sensors are
normally measure level within a specified range, especially it related
with the exact amount of liquid in a certain place. In other hand,
Point level sensors only measures a specific level, and it’s used to
detect high level or low level alarms!
It’s quite an easy project, where there
are very few electronic components being used here. You only need an
PIC12F683, two resistors (one 100 ohm and one 10K ohm), a 0.1uF
capacitor, a HCM1206X buzzer and 4.5V batteries. Then, you only have to
put all the things together and you’re done with it!
