TGS4161 CO2 Research Arduino Project Hub

Accuracy: If used correctly the sensor is VERY accuarte. I am comparing it to my K30 CO2 (which is rated ~3% accuracy) and I can tell that response times and readings are within 5% difference. Yet this is true only in case the TGS 4161 is correctly calibrated and used. The following section lists my findings in this area up to now.

Arduino CO Monitor Using MQ7 Sensor : 8 Steps (with ...

But here''s the problem: Arduino can''t provide enough power to run this sensor from its pins sensor''s heater requires 150 mA, while Arduino pin can provide no more than 40 mA, so if attached directly, Arduino pin will burn and sensor still won''t work. So we must use some kind of current amplifier that takes small input current to control large output current.

How to use KE25 Oxygen Sensor with arduino

24/08/2020· 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.
