The Electricity sensor module is based on the TA12-200 current transformer which can change large alternating current into a small amplitude. You can use it to test large alternating current upto 5A.
Features
Grove compatible interface
Maximum 5A input
High accuracy
Small size
Applications
Alternating current measurement
Device condition monitoring

Hi,
How would be this conversion formule with 3,3 Vcc and 12 bits ADC:
amplitude_current=(float)sensor_max/1024*5/800*2000000;
effective_value=amplitude_current/1.414;//minimum_current=1/1024*5/800*2000000/1.414=8.6(mA)
What happens if in my wire there is a current of +/- 5A? What is the output?
I'm using this sensor to detect current. But something is wrong. If my device goes on, it takes 150mA, if not then 0mA. I can measure it using AV-Meter. If I use this sensor with the demo code, it shows me only the changes (0mA then 150mA then back to
I bought this device, but i don??t know how i can measuring the current,somebody could help me, please.
Looks like a great component, I have never seen current transformers this accessible. But, is this available with other input values? This one is 1000:1 (5A/5mA), but 100:1 (500mA/5mA) and smaller may also be useful to measure smaller AC currents accur
