      Description

      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

      For all Grove users (especially beginners), we provide you guidance PDF documents. Please download and read through Preface - Getting Started and Introduction to Grove before your using of the product.

      could I use it to measure ac sine wave current and get the complete sine wave using arduino uno ?

      What a great little sensor, but it would sure be nice to make the toroid clamp around existing cables. There's no easy way to put this on an existing AC wire without cutting / splicing the wire.

      This doesn't have an reverse-voltage protection, does it? Won't it damage the analog pins on the Arduino? I need to use this simply to detect if the AC power is ON or OFF. The current draw on the AC should be ~2-5amps.

      hi,
      I use the arduino sketch of the wiki, but I got wrong values (for example 1000ma instead of 17mA). does anyone have ever use this to build a powermeter?

      Hi Terry, I'm using a different platform of Arduino with other microcontroller ( TI cc2530) and I want to use this sensor with my platform. My platform uses a cc2530 SoC and it has a 12 bits ADC and uses 3,3 V as VCC. For that, I need to adapt the conv

      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

      <p>Just got answer from techsupport : This sensor is only for AC current and NOT for DC current.</p>

      <p>Hi, view the WIKI. There are demo code for the sensor, upload to Arduino or seeeduino board and plug to the right pins then you can use Arduino IDE monitor the value.</p>

      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
