The circuit of a low water level alarm is described. This circuit can be used in many water level detection applications, and is ideal for use in vehicles; a good example is to give early warning of a low windscreen wash water level. The LM 1830N is used with a filter capacitor to ensure that the output transistor is turned on with a DC signal. A 'low level' warning LED illuminates as soon as the water level drops to an appropriate point.
