hi guys, i need help from u guys, i search the net but ddint get the answer to wad i want. my question is : What are the advantages and disadvantages of using a LC filter as compared to a RC filter? please help me. thanks :|
hi
the sensor is a normal iR sensor which can be get from the market easily. cant i use an AC to power up my dc sensor circuit by a transformer or sumtin?
Hi,
i need some help regarding a project that i am doing now. i nid to know how do i go about connecting an 230VAC fan to a dc sensor. the dc sensor will control the power and oscillatory of the fan. is the method from the power supply socket, its connected to the dc sensor, then the output...
hi..... thanks for the reply... i do have the picture of the done circuit but not the schematic diagram... will post the pic later.... here are the requirements of the sensor fan that i nid to do as part of my project:
A. Make a power supply circuit for the sensor.
B. Your sensor circuit...
bro's... thnx for the reply... it help me in a way or another... i have another qn that i nid some clarifications.... my circuit is done with the soldering and etc on the PCB board... so u mean to say that i need a relay to connect my circuit to the 240VAC supply of the fan or is it not? my...
Hi, i need help in connecting a sensor circuit to a present circuit that i have. i need to know where i can connect a sensor circuit to the fan. the sensor circuit consists of an infrared sensor and a 555 timer. please help me. thank you.
