Does the device use a current transformer CT?

But, I am aware there are some requirements relating to the types of capacitors that are used. Notify me of new comments via email. Notify me of new posts via email. Anyway, a resistive shunt is used for the low cost current measurement and a custom IC handles all the power measurement calculations.

Or a resistive shunt which would be much cheaper?


This device would be interfacing to the CS via the serial interface. 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.

For the low price, how is the current measured. When in service, current from datahseet 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.

This would be used for the auto-boot function described in the CS datasheet and it would contain calibration and configuration settings. A flat blade screwdriver is useful for prising the case apart. I found it easier to prise the unit apart from the bottom. You are commenting using your Facebook account. Check out this linkit has some good overview information regarding mains datashset caps.


Also, is there any scope to hack the device, similar to the Tweet-a-Watt? Once the case is apart, the internals are quite compact.

A bonus is that the serial interface pins are clearly labelled on the PCB adjacent to the ribbon cable on the top right. There is some scope for customisation here. Is there some sort of custom IC performing the energy measurement?

Immediately, a resistive shunt used to measure current can be seen on the bottom right of the green PCB. 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.
