Automotive Fuel Monitor Five

Published:2011/7/17 5:56:00 Author:Felicity | Keyword: Automotive Fuel Monitor

The circuit consists of oil level monitoring circuit, the oil level indicating circuit and lacking fuel alarm circuit. Oil level monitoring circuit consists of automotive fuel tank float potentiometer RP, resistors Rl, R2 and capacitor C. The oil level indicating circuit consists of R3-R8, RlO-R13, LED VL1-VL4 and quad op amp IC IC (Nl-N4). Lacking fuel alarm circuit consists of resistor R9, transistor V and buzzer HA. The voltage divider circuit consist of R3-R8 and the circuit provides standard oil level voltage for the non-inverting terminal of N1-N4 inside IC; The voltage divided by R1 and RP and then put on to inverting terminal of N1-N4 through R2 as the oil amount sample voltage. When the fuel tank is full of oil, the resistance of RP is at its lowest and N1, N3, N4 output high level voltage, VL2 output low level voltage. And the yellow LED VL2 is on indicating the fuel tank is full. When the tank is 3/4 full, N3 also output low level voltage to make green led VL3 on. When the tank is 1/2 full, N4 also output low level voltage to make green led VL4 on. When the tank is 1/4 full, N1 also output low level voltage to make red led VL1 and V on. And the beeper beeps to remind the driver to refuel.   (View)

Automotive Fuel Monitor Two

Published:2011/7/17 6:04:00 Author:Felicity | Keyword: Automotive Fuel Monitor

The circuit consists of comparator, the monostable flip-flop and warning lamp circuit. (It is showed in picture 7-59.) Comparator consists of divider circuit (by the resistors Rl-R3 form) and integrated operational amplifier circuit ICl. The monostable flip-flop consists of time-base integrated circuit IC2 and the peripheral components. Warning lamp circuit consists of transistor Vl, V2, and light-emitting diode VL. Pin 2 (inverting terminal) of IC1 is connected to the center head of RP,the potentiometer, through R4. When the fuel is enough, pin 6 of IC 1is at high level ,V1 and V2 both cut off. When the amount of fuel is below a certain value, pin 6 is at low level. And then V1 and V2 is on to light up LED VL; The monostable flip-flop inside IC2 flip, changing from steady-state into transient-state. Pin 3 of IC3 is at high level,and the beeper HA works. When C3 is end of charge, IC is at steady-state again. Pin 3 is at low level and HA stops. But LED VL shines until the fule tank is refilled.   (View)
