Its my first time working with analog sensors. And I have few doubts.
What do you EXACTLY mean by pre-heating?
Is it leaving the sensor on for 24 hours (For MQ135). 24 hours because its mentioned in the datasheet.
Do I have to do something else when I leave the sensor on for 24 hours. I am planning to just make a simple connection with Arduino Uno and the MQ135 sensor and leaving it on for 24 hours in fresh air.
Connections: Ard A0 to Sensor A0
Ard VCC to Sensor VCC
Ard Gnd to Sensor Gnd
the code will be simply taking raw values of the sensor. No calibration nothing for now.
I just want to know pre heating means leaving it on for 24 hours right? Nothing else right? Because there is no articles actually mentioning how do you pre heat sensors! PLEASE HELPP!!!!
