Ammonia Sensor. Sensors Arduino Forum

May 06, 2021· The ammonia gas sensor you looked at will meaure ammonia in air, and it is less sensitive than your nose is. Yes, That is my ideas, I want to determind the total concentration of ammonia in aquarium water. It consists of NH3 and NH4+. As I know, to determind the concentration of NH3, we have to measure the pH and total concentration of ammonia.

Atmospheric Air Analyser Arduino Project Hub

The necessity of Arduino Nano arises when data from sensors is to be sampled. The gas sensors output Analog data and hence the MCU must have at least 3 analog pins (since we used 3 gas sensors here; could be scaled up to a larger number) to read this analog data. As NodeMCU has only 1 Analog input pin (A0), it makes it alone isn''t fit for the job.

Arduino Light Sensor | Arduino Tutorial

Arduino Light Sensor. Arduino Uno''s pin A0 to A5 can work as the analog input. The analog input pin converts the voltage (between 0v and VCC) into integer values (between 0 and 1023), called ADC value or analog value.. By connecting a pin of the photoresistor to an analog input pin, we can read the analog value from the pin by using analogRead() function, and then we can know the light ...
