TankBot is a really complete module, in that way it will be the last one installed.
We'll start by connecting the PH probe and the water temperature sensor that comes with the kit.
We add also an EC probe if we have one.
In this example, we'll connect to the outputs 4 devices.
two electro valves,
and two peristaltic pumps.
In the input sockets we connect the two switch sensors to analyse the water tank level,
one smoke detector and a motion detector.
TankBot supports four 12V independent outputs and four switched sensors.
All this elements must be positioned in our area or grow and in your water tank
before you connect them to TankBot. With exception of the EC and PH probes.
This last ones we need to calibrate them before we place them in our water tank.
Before you calibrate the EC and PH probes
we need to ensure that we clean them with distilled water and fully dry them to avoid tampering with the calibration solution.
Next, we need to have ready the calibration solutions for PH 4 and PH 7,
That are provided with your kit.
We pour the solutions into a cup to easy the process.
In the application we'll click on the probe name so we can access its configuration menu,
and next click on Calibrate Sensor.
We insert the PH Probe in the PH 4 calibration solution, and we stir it to accelerate the process.
We let the probe rest in the solution for a minute.
In the application you click on GO PH4 calibration button.
Next, we clean the sensor by submerging it in distilled or tap water
and we clean it to avoid tampering with the next calibration solution.
Now, we repeat the process with the PH 7 calibration solution.
We get back to the application and we press the GO PH 7 button.
To calibrate the EC sensor, we dry the sensor and leave it in open air to calibrate the minimum value.
Next, we submerge it on a calibration solution of 1413us
and we press the maximum calibration button.
Once your probes are calibrated, we suggest you place them in a floating base, you can use the foam in your kit.
In this way, your sensors will always stay at the correct level inside the water tank.
It's possible that your level sensors, or other switched sensors,
have the polarity switched.
To reverse the polarity of a switched sensor, we'll click on the state square and reverse the polarity
so we get the correct value for the sensor.
We can see the default state of the sensor, changes from closed to open.
Last but not least, we'll see how can we control the power/speed of the last two outputs of TankBot.
This is very useful to control LED intensity,
or the speed of a electric motor.
In this example, we have a peristaltic, and by reducing the speed we can
get improved precision when we want to add liquid fertilizers or PH regulation solutions in our water tank.
By default the value is 0. This means your output will work or fully on or fully off.
Equivalent to the 100 value of speed.
To change the new speed we need to change this value, and save the configuration.
We repeat the process until we get the desired speed or light intensity we need.
Test this values for different devices, until you reach the desired one,
different motors can have different minimum valid values.
And that's all.
Now you reach the moment where you need to configure your Areas and Grows.
