Fluke 189 Multimeter - Web interface

thingiverse

Using the Fluke 189's built-in IR serial interface, you can send and receive data without breaking the bank by opting for a DIY WiFi solution instead of shelling out $60 for a fancy Fluke IR serial cable. To get started, combine a phototransistor with an IR LED and a cheap ESP8266 ESP-01 WiFi module that costs only around $3. This setup will allow you to read your meter remotely from any web browser and even control certain parts of the device. This project was a blast to work on, but I probably spent way too much time on it. My goal was to create a solution as cost-effective as possible. The Arduino code for the ESP8266 is available below, so feel free to use it and ask me any questions you may have. To see this project in action, check out my YouTube video at https://youtu.be/k6FPeUcDfpc. Here are the parts you'll need: * Toggle switch * 10K ohm resistor * 470 ohm resistor * IR LED * Phototransistor * ESP8266 ESP-01 * LM1117-3.3v regulator
