Check datasjeet this linkit has some good overview information regarding mains rated caps. A bonus is that the serial interface pins are clearly labelled on the PCB adjacent to the ribbon cable on the top right. This device would be interfacing to the CS via the serial interface. Also, is there any scope to hack the device, similar to the Tweet-a-Watt? There is some scope for customisation here. For the low price, how is the current measured. 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.
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. Sorry, your blog cannot share posts by email. Once the case is apart, the internals dahasheet quite compact. A flat blade screwdriver is useful for prising the case apart.
Current measurement is performed using a resistive shunt. This would be used for the auto-boot function described in the CS datasheet css it would contain calibration and configuration settings. I found it easier to prise the unit apart from the bottom. 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. You are commenting using your Facebook account. Cs in your details below or click an icon to log in: Is there some sort of custom IC performing the energy measurement?

Anyway, a resistive shunt is used for the low cost current measurement and a custom IC handles all the power measurement calculations.
