Very professional!
For pH DO ORP DO EZO Chemistry Circuit Module Carrier
I have an WeMos ESP8266 datalogging ORP and pH from my swimming pool. I use the Atlas Scientific modules in I2C mode. All works well for a few months and then the data goes crazy. I'm pretty sure the problem is contact tarnishing with my cheapo breadboard that connects the Atlas modules. The Tekinetics boards look like a great solution to clean up this problem. I'll know in a few months!
