NDIR CO2 Sensor code queries Adafruit customer service ...

16/07/2017· Re: NDIR CO2 Sensor code queries. by adafruit_support_mike on Sat Jul 15, 2017 1:01 am. 1) The output value is being calculated in millivolts, and there are 5000 millivolts in 5v. 2) 16/50 calculates voltage in terms of ppm: v=ppm*16/50. To calculate ppm in terms of voltage you have to invert the equation: ppm=v/ (16/50)=v*50/16.

The Adafruit PCT2075 Temperature Sensor is a ''code compatible'' dropin replacement for a very common I2C temperature sensor, the LM75. Compared to the LM75, however, the 11bit ADC in the PCT2075 provides more precise measurements when compared to the LM75''s 9bit ADC. Additionally, because the PCT2075 allows the address pins to work in three states (high, low, floating), you can …
