Water level sensor for car fuel filters, has self test function through simple time delay circuit |
摘要 |
The water level sensor has an electrode sensor (S) connected to a time delay circuit (R2,C1) and MOSFET switch (Q) so that when the supply voltage (U) is connected during the time delay a signal is produced even if the electrodes do not contact the fluid.
