Warning: I'm a nubie at both Arduino and getting info from Forums. I searched, but did not find a similar topic, so am posting myself.
What I would like to do is to measure amperages (for, say, a motor) and save to the cloud. The goal is not accuracy (revenue grade), but a general idea as to when a device is operating. The hardware required, starting with the device being measured:
- Current Transformer. (I have sourced these out. They have a peak AC output of 1Vrms or 1.4V peak.)
- Full Wave Rectifier to convert AC to DC. (I have created this using diodes and a capacitor. I am getting a steady DC output voltage between 0V and 1.4V depending on amperage of motor.)
- WIFI Shield or WIFI component.
- Internet connected WIFI Router.
For the software development, I will likely hire someone to do it...I don't have the time and the last time I programmed was early '90's Fortran.
My questions are around the hardware. a) Do I have the right approach? b) WIFI Shield/Component. What should I use here. The goal is to have something robust that can communicate over a distance, say 100'. This is my biggest question. c) Should I be using or at least investigating other wireless options? Zigbee?
Thanks in advance. Old dog trying to learn a new trick.
