Product Description
Add the ability to measure pH, ORP, or any mV probe to your Arduino or Raspberry Pi project.
Some quick facts...
- boards are assembled and tested in-house
- hardware and software files are open-source
- designed with simplicity in mind
Why we're better than the other our competitors...
- just as accurate
- significantly easier to use
- all-inclusive system, no need to buy connectors
- a temperature sensor is available on all the boards
Measure pH or ORP
- measure pH with temperature compensation
- measure ORP and Eh
- read the raw mV output of any ion specific probe
- read temperature in Celsius/Fahrenheit
What it is
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.
Using it
There is extensive documentation on the specifications, setup, and use of the device.
The library to use it is in the Arduino and Particle.io IDE. A python and rust implementation for Raspberry Pi is available. There is also a MicroPython library.
Example Projects
Here are some Instrucable links to projects using this:
IoT Pool Monitoring using ThingsBoard.io to graph the data
IoT Hydroponics - Using IBM's Watson for graphing and another hydroponic system using Adafruit.io.
ESP32 Bluetooth Interface
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.
