A flat blade screwdriver is useful for prising the cs5640 apart. Immediately, a resistive shunt used to measure current can be seen on the bottom right of the green PCB. You are commenting using your Facebook account. For the low price, how is the current measured.

Does the device use a current transformer CT? At that price, I was curious, how does someone manufacture and sell for some sort of profit a device that can measure up to W of power. The two heavy gauge wires are the active connection. Also, is there dagasheet scope to hack the device, similar to the Tweet-a-Watt?

There is some scope for customisation here. Post was not sent – check your email addresses!

A bonus is that the serial interface pins are clearly labelled on the PCB adjacent to the ribbon cable on the top right. I found it easier to prise the unit apart from the bottom. Reviewing the datasheetthe device is a dedicated chip for performing voltage, current and energy consumption calculations.

Once the case is apart, the internals are quite compact. Or a resistive shunt which would be much cheaper? Anyway, a resistive shunt is used for the low cost current measurement and a custom IC handles all the power measurement calculations. When in service, current from the rear male prong connects to the obscured red wire, passes through the resistive shunt and then through the other red wire to the front female contacts.

Current measurement is performed using a resistive shunt. Share your thoughts Cancel reply Enter your comment here You are commenting using your WordPress. It appears that the circuit is using an X2 type capacitor — used to filter out differential mode noise and is connected between active and neutral. This device would be interfacing to the CS via the serial interface.

This would be used for the auto-boot function described in the CS datasheet and it would contain calibration and configuration settings. You are commenting using your Twitter account.
