To limit the input current from 400mA to 100mA, I have connected 100 ohm resister in series with the input voltage(7.5V). before connecting the resistor to the sensor I measure the current and voltage,
V= 7.5
I = 40mA.
But after connecting the resistor to input pin and i measure the voltage...
Yeah in that way only i had measured it.
The reason why i asked about the current rating is, as i mentioned previously the Gunn model MO86735 (sensor which detect motion sensing) data sheet also mentioned the max current range is 200mA but it worked with 300 to 400 mA.
So if the above mentioned...
I had just connected 3.3K load resister across the mixer output and ground. i didnt connect any capacitor.
i had measured input current is around 300mA. is this one can cause trouble in sensing motion??
Thanks for conforming that my transceiver is working. But it seems still my problem persists. I am not even getting any deflection in µ ammeter. I had checked the ammeter and it is working properly.
I had borrowed another type of transceiver model no MO86735 (which has connected with 1k...
That really great explanation. thanks
But the problem is i am not getting any deflection in ammeter or oscillator.
as a result i got
Input voltage : 9.5V
555 Output : 9.0V
sensor input : 7.5V (I don't know why its coming like this?? because without connecting sensor i measured 555 output in...
As u told i had tried giving pulse using 555 timer using this circuit
Input voltage: 7.5V (measured in multimeter or VOH meter)
Output at CRO : 7V (while measuring in multimeter or VOH meter it shows 4.8V).
But i cant able to see any current variation in micro ammeter when connected to o/p...
thanks brian. but the data sheet says i have to give pulsed DC input. how to give it. is it i have to connect any other component with the sensor to check it??
hello guys,
Is anyone used Gunn transceiver sensor developed by microsemi.
I am using MO9081 gunn transceiver. i would like to know how to test the gunn transceiver
and how to check the speed variation through that sensor.
i also need to know the connection setting for that transceiver...
Well thanks for the clearance.. can u pls look at the above code which i had attached ...can u say whether i a m going in a rite way or not.. if not can u direct me in rite way please
It's is similar to 8051 or 89c51 MCU. when i contacted the motor supplier he told that the motor will only get drive it the output frequency is n the range of 200khz. From investigation from other sources i found , i need to pass some value with pulse signal to run the motor. i dono how to pass...
IT seems like to drive the motor i need to frequency in the range of 200khz. and is that possible to obtain 200khz in MCU if means can u say how to achieve it?
And you have mentioned that send the pulse to PUL. if you dont mind can u say how to generate the pulse from MCU pls give some examples...
Hello guys
i am trying to interface P89v51 rd2 controller with stepper motor. i had bought the stepper motor with drive. please see the specification of
stepper motor in below mentioned link.
Stepper motor:

i am trying to...
i need to count number of time the LED gets turned off... for that i had used external interrupt... but the problem is when i call the interrupt the count increases by 2 when led turned on and it increase again 2 when turned off.
In debugger mode my program works prefectly.. but while...
Guys i m trying to count the no of objects passing in a conveyor belt. for that purpose i am using IR sensor. When sensor goes low it have increase the count by 1.
Now the problem is in the debugger mode it increments the count properly. but while displaying in LCD it increment the count...
Well thanks for the reply
@nandhu015 : i have tried your idea but its not working.. still the problem persist
@eklikeroomys : this my first program. this might be silly but i had no other way
can you help to write interrupt.. can u give me any sample program using interrupt like which...
