LM1830 low level fluid detector circuit
In some applications we need to detect the presence of the liquid is in some recipients . For this we can use a low level fluid detector circuit which can inform us when the liquid in recipients has low level . This LM1830 low level detector schematic circuit based on the LM1830 low level detector IC require very few external components and is very easy to build .
This LM1830 low level detector can use an audio indication (speaker ) or a visual indicator (LED- light emmiting diode ) that will light when the level is low . This low level detector circuit will generate a 500 Hz audio signal when the level is low .
This low level detector require a 16 V DC power supply and the recipient must be from some metal , because you need to connect the ground of the circuit to the recipient .
The IC used for this low level detector is a integrated circuit designed for use in fluid detection systems.
