How to use KE25 Oxygen Sensor with arduino

20200824· KE25 oxygen sensor. This sensor is self generated voltage, so it doesn’t need any voltage source to operate. But it has so small voltage output. So to make easier to read with an arduino. We should amplify the sensor first. I use an LM358 op amp IC to amplify the sensor output. I amplify the sensor 11 times. So i use non inverting op amp ...

Measure CO2 Levels With Ardunio and K30 Sensor : 9 Steps ...

While the Arduino''s 5V power is theoretically able to power the K30, the sensor needs 300mA minimum to operate the light inside the sensor. The problem is, if you power the Arduino from your PC''s USB port, the K30 has to share power with the Arduino, your mouse, and any other devices on the USB bus. The power to the sensor will drop under 300mA, and it won''t operate properly.

Read O2 sensor directly with arduino ... Adafruit Industries

20140102· I want to read a narrow band ("OneWire") oxygen sensor with the Arduino ATMega2560. The maximum output of the sensor is about (analog) +1 volt, so that''s not a problem. But, as the sensor warms up, the output voltage actually drops a little below zero, maybe as low as negative 50 to 100 millivolts just before it starts sending useful data. (Although I don''t think I have actually seen anything ...
