The Seeed Studio O2 sensor is a nice Oxygen sensor. It works up to 25% Oxygen concentration and is easy to use in an Arduino project.
http://wiki.seeedstudio.com/Grove-Gas_Sensor-O2/
If you look on the back of the sensor there are only 3 wires used. VCC, GND, and a SIG. The NC pin is “Not Connected”
Wire the
GND -> Arduino ground
VCC -> Arduino 3.3V (Looks like it may also accept 5V)
SIG -> A5 (Analog 5)
Copy and paste the following code into the Arduino IDE
// Grove - Gas Sensor(O2) test code
// Note:
// 1. It need about about 5-10 minutes to preheat the sensor
// 2. modify VRefer if needed
const float VRefer = 3.3; // voltage of adc reference
const int pinAdc = A5;
void setup()
{
// put your setup code here, to run once:
Serial.begin(9600);
Serial.println("Grove - Gas Sensor Test Code...");
}
void loop()
{
// put your main code here, to run repeatedly:
float Vout =0;
Serial.print("Vout =");
Vout = readO2Vout();
Serial.print(Vout);
Serial.print(" V, Concentration of O2 is ");
Serial.println(readConcentration());
delay(500);
}
float readO2Vout()
{
long sum = 0;
for(int i=0; i<32; i++)
{
sum += analogRead(pinAdc);
}
sum >>= 5;
float MeasuredVout = sum * (VRefer / 1023.0);
return MeasuredVout;
}
float readConcentration()
{
// Vout samples are with reference to 3.3V
float MeasuredVout = readO2Vout();
//float Concentration = FmultiMap(MeasuredVout, VoutArray,O2ConArray, 6);
//when its output voltage is 2.0V,
float Concentration = MeasuredVout * 0.21 / 2.0;
float Concentration_Percentage=Concentration*100;
return Concentration_Percentage;
}
Upload and Launch the Serial Monitor
Tools -> Serial Monitor
or
Ctrl + Shift + M
Need to Specify the serial input
Start the serial connection
Print input to log
// Set analog pin variable
const int aPin = A0;
void setup() {
// Start Serial connection
Serial.begin(9600);
}
void loop() {
// Print analog input to Serial Monitor
Serial.println(analogRead(aPin));

Using an O2 Sensor which has the following connections
SSH into the UniFi. Note that the UniFi username and password get updated from the controller. Refer to here to find username and password.
ssh ubnt@192.168.1.20
run the syswrapper.sh script with the restore-default option.
syswrapper.sh restore-default &
set-default &
Note that this changed. Used to, you could just run syswrapper.sh restore-default and it would reset. Now if you do that, it won’t reset, you’ll be able to ping the device, but you can’t ssh into it meaning you will need to physically reboot it.
Once the device is reset, log in over ssh and reconfigure.
Note that the username and password will now be ubnt/ubnt
In the newer controller versions, you should be able to go to
Settings -> NETWORK SETTINGS -> Device Authentication
To view the SSH credentials.
Go to Settings -> Site -> DEVICE AUTHENTICATION

sudo docker pull jacobalberty/unifi:5.6.42

Looks like you can use Darling to run MacOS command line applications in Linux.
Helpful commands. Maybe?
Looks like most of the configuration scripts are in /sbin

Seems like I am missing a step. Seems to change the password in the nvram, but does not actually change it permanently
