Arduino Sen0159
totunco 2016-12-17 04:19:08 14139 Views8 Replies Hi,
I bought a sensor sen0159 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? How can i see the status of heating?

Ok, I understand. If you connect the 5V and GND to the + - near the sensor, its no problem. Then sensor will be able to work normally.
According to your diagram , its should be no problem. Probably its the problem with the probe. Under the warranty, you are entitled to demand a replacement (no need send the broken one back to us). You can go to your order page to apply the RMA, then our store will deal with your needs ASAP.
let me know if you have any problem. Wendy.Hu

Thanks for your courtesy

totunco 2016-12-21 01:37:31 Sorry but i'm only a beginner 
in the first picture that i sent you i followed the scheme of the site. in the picture that i sending there are the connection of which i spoke(the GND and the V near the D pin). Can i use this? totunco

LED on the board is not a power indicator, which is used for signal prompts. For example, when the concentration exceeds the threshold, the light will turn on. There is a potentiometer on the board, can be used to set the threshold.
I am not very clear about 'What happens if i connect the V and the GND that are on the right side of the sensor(near the digital pin)?' Can you point out in the picture? And can you give me another more clear picture, especially the position of the wiring pin? Since probably its the wiring or probe problem. Thanks for your patience. Wendy.Hu

Wendy.Hu 2016-12-20 10:03:27 this is how i connect the sensor, 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)?
you can see that the led intensity is too low
thanks for the answer totunco

Sorry for your troubles.
It sounds like there are some problems with the probe. Would you mind to provide me some pictures about your diagram? Then did you refer to our wiki to add a external power supply to Mega2560? These might be helpful for us to understand what happened. And the amplifier you mentioned I guess its a boost chip, its normal when you are heating the sensor.
Looking forward to your reply. Wendy.Hu
