    voltage sensing circuit

    Hi, you can connect the load like you say and in parallel you can connect two resistors in serie, 10K and 1 K and then monitor the voltage measuring the 1K resistor. Or you can change the values of the resistors for another level of voltage in one of them and after that you can apply a bridge...

    voltage sensing circuit

    I do not know how complex you are intending to develop your project but Analog Devices offers a very powerful IC that senses all the parameters regarding energy, current and voltage. I implemented it in my thesis. Take a look, ADE7754 or ADE7758. regards

    temperature sensor lm35 (how it works)

    Basically it is a precise temperature sensor which has 3 main connectors. VCC, GND and OUTPUT. The first and second are fix values of your circuit and the third , it means the OUTPUT provides a voltage proportional to the temperature. Then you can connect a resistance in serie and measure also...

    CANOE tool details (share ur idea)

    Hi gomathigururajan, CANOE is a platform where you can simulate and implement different kind of nodes. It can be through CAPL or MATLAB. It is aimed at the industry of cars but it can be used within other applications. In my case I am working on a simulation in the field of Marine. regards Alberto

    Possible test multifunction energy metering IC ADE7758?

    Re: Anybody tested multifunction energy metering IC ADE7758? Can you tell me if the sensor at least works when you change the temperature changes? Maybe you have a problem with your SPI configuration, I had that problem at the beginning. regards Alberto
