GAOHOU PH0-14 Value Detect Sensor Module + PH Electrode Probe BNC For Arduino
Getting the voltage varies on what you’re using. The PH for this sensor is not at 0v for a PH7 it’s around 2.51v from the multi-meter and PH4 at 3.03. If you calculate the step, 2.51-3.03 =-0.52. The difference between ph4.01 and PH7 is 2.99..
If you’re using a Particle product like the Photon or Argon, be aware of a bug. It’s a hardware issue with the analog ports fluctuating a ghost voltage. This fluctuation is enough at these low voltages reading to make your ph sway by .7 or more. To fix this, you’ll need to add a 0.1uF cap between the analog port your using and ground..
This PH electrode probe must be calibrated with standard buffer solution before each use, and the electrode probe cannot be tested continuously for a long time, which will shorten its life. There are two trimmers on the circuit board. One of them is for offset adjustment (closest to BNC connector) accomplished by removing the Ph probe and shorting the BNC connector with a wire. The other trimmer is an upper limit threshold for the digital output pin..
Update From kuman 13803KThe sensitivity of DSO Shell oscilloscope has been extended in both directions and is higher and wider than DSO138 oscilloscope. It reaches 5mV/div --- 20V/div while DSO138 is only 10mV/div --- 5V/div.
More Applications Display and MCU are now mounted on the same board (mainboard) to avoid using inter-board pin-headers, Analog channel is placed on a separated board which contains most user install parts. This brings in better separation between analog and digital circuits. Without the analog portion the mainboard can be used in many other applications..
Rotary encoder has been added It makes parameter adjustment much quicker and easier..
DSO Shell comes with full enclosure The front panel and top/bottom brackets are flexible for easy user modification..
Detailed InstructionDetailed assembly instructions are provided in combination with troubleshooting guide and schematic..
