plee,assist me to read the below circuit and give the details information of each device(component) employed in the circuit i.e op-amp, diode, resisters and relay.also,provide me with the formular used to the value of resistors and the type of op-amp(741).i ahave failed to cooy the circuit
i want to design a light depended circuit together whith its power supply.i preffer to use LDR as the sensor and LED as the indicator.i need an assistance from all of you to make such a circuit.
i want to design a switch which will be on when there is light and off when it is dark.i preffer to use LDR as my sensor and LED as the source of light.please provide me suggestions and the circuirt.
i want to design a simple circtuit that will detect the presence water in a fuel tank.i want to use the theory of conductivity but till the moment ihave no exactly figure of water and fuel conductivity.please also assist me to get dielect costant of these two liquids.
i hope your well according to my heading, i need simple circuit
that will transmitte a/v signal within 15 m range and its operate
in vhf band ,channel 3 applied, together with technical description
how it operates .also if possible i need a cost estimatimation for construct
prototype
regard...
thank you for response of my previous title water/oil detector.but iam changing my title to that on the subject.my idea is to detect that there is water in a fuel(petrol or disel) stored in a tank.but iam restrict those whom are intrested to assist me in disign not include computeron that...
water/fuel mixture detector
iam happy with your response on my previos comfunsing title(water/oil mixture detector).now,iam making clear that i want to build a circuit which will detect that there is content of water in a tank filled with fuel(petrol or disel).the circuit should be simple and...
i want to design a circuit which will detect pressance of water in a water/fuel mixture.i want to use the idea of conductivity or ability of light to penetrate on those liquids.
