Ion Specific Electrode Probe Interface
Add the ability to measure pH, ORP, or any mV probe to your Arduino or Raspberry Pi project.
- boards are assembled and tested in-house
- hardware and software files are open-source
- designed with simplicity in mind
- just as accurate
- significantly easier to use
- all-inclusive system, no need to buy connectors
- a temperature sensor is available on all the boards
An I2C sensor device that can read any voltage based sensor such as a pH or ORP probe. There are pin headers available to connect a DS18B20 temperature sensor for temperature compensation. The firmware on the device provides two calibration options, single or dual point. The hardware and all firmware/software is open source and available for anyone to modify or improve upon.
Here are some Instrucable links to projects using this:
To make getting started quicker for everyone, an ESP32 Bluetooth Low Energy library is available. It requires little to no programming experience and provides a graphical front-end for showing the measured values from the probe interface. It works within the Chrome browser on any device with a Bluetooth adapter. A Websockets version is also available.
Take advantage of volume pricing and get 10% off the regular price for the board and probes.
