Arduino | Adafruit SCD-30 - NDIR CO2 Temperature and ...

Jul 09, 2021· The SCD-30 is an NDIR sensor, which is a 'true' CO2 sensor, that will tell you the CO2 PPM (parts-per-million) composition of ambient air. Unlike the SGP30, this sensor isn't approximating it from VOC gas concentration - it really is measuring the CO2 concentration! That means its a lot bigger and more expensive, but it is the real thing. Perfect for environmental sensing, scientific ...

Really Homemade Oximeter Sensor - Arduino Project Hub

May 13, 2020· The KY-039 sensor has a S (signal) pin to read that changing value. We can measure heartbeat rate by counting peaks of the signal. Reading a value from a variable signal from a sensor it's not so easy, because there is a lot of noise, the signal is really low, and we need to make some math to find the good values to plot.

How to use KE-25 Oxygen Sensor with arduino -

Aug 24, 2020· KE-25 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.
