Also, is there any scope to hack the device, similar to the Tweet-a-Watt?
Energy Meter Teardown – SteelCity Electronics
At datzsheet 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. But, I am aware there are some requirements relating to the types of capacitors that are used. Learn how your comment data is processed. Sorry, your blog cannot share posts by email. Once the case is apart, the internals are quite compact.
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. 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.

Or a resistive shunt which would be much cheaper? This site uses Akismet to reduce spam. A flat blade screwdriver is useful for prising the case datasjeet.
Energy Meter Teardown
Is there some sort of custom IC performing the energy measurement? For the low price, how is the current measured.
There is some scope for customisation here. Post was not sent datashee 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.
The two heavy gauge wires are the active connection. Fill in your details below or click an icon to log in: Notify me of new comments via datasheet. Current measurement is performed using a resistive shunt. Check out this linkit has some good overview information regarding mains rated caps. Share your thoughts Datasueet reply Enter your comment here Notify me of new posts via email. Reviewing the datasheetthe device is a dedicated chip for performing voltage, current and energy consumption calculations.
I found it easier to prise the unit apart from the bottom.
Immediately, a resistive shunt used to measure current can be seen on the bottom right of the green PCB. Anyway, a resistive shunt is used for the low cost current measurement and a custom IC handles all the power measurement calculations.
Email required Address never made public. Does the device use a current transformer CT? You are commenting using your WordPress. 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. This device would be interfacing to the CS via the serial interface.
