Hi,
I bought a sensor sen0159 from dfrobot for CO2 monitoring in my project with arduino 2560, but when i connect the analog pin, the 5V, the GND and after i upload the sketch, i look after more than six hours that the sensor is cold, the only thing that become hot is the sensor's amplifier.
Is this normal? Anyone knows how i can see the status of heating?
The sensor should be 30..40deg C. Other components should feel cold..
Defective booster ? ? Remember 7..12v to Vin or barrel jack
i tried to feed arduino with jack or with the usb but i have the same results (also with the jack after a few of seconds the led on the sensor turns off).
What happens if i connect the V and the GND that are on the right side of the sensor(near the digital pin)?
Your breakout board has a datasheet. Study it.. there may be important details..Like connections and example code
ok thanks!
