LM1830 Fluid Detector  
General Description  
Features  
Y
Low external parts count  
The LM1830 is a monolithic bipolar integrated circuit de-  
signed for use in fluid detection systems. The circuit is ideal  
for detecting the presence, absence, or level of water, or  
other polar liquids. An AC signal is passed through two  
probes within the fluid. A detector determines the presence  
or absence of the fluid by comparing the resistance of the  
fluid between the probes with the resistance internal to the  
integrated circuit. An AC signal is used to overcome plating  
problems incurred by using a DC source. A pin is available  
for connecting an external resistance in cases where the  
fluid impedance is of a different magnitude than that of the  
internal resistor. When the probe resistance increases  
above the preset value, the oscillator signal is coupled to  
the base of the open-collector output transistor. In a typical  
application, the output could be used to drive a LED, loud  
speaker or a low current relay.
