I am working on a test project that will require an electrochemical N02 sensor. This is my design as shown below. It works very well. But I have noticed that the power supply must be very stable, otherwise you need to let the sensor stabilizes before having any accurate results.
The sensor is connected to a PCB, that has a GSM module. I am suspecting, that there could be some circumstances where the current consumption for the module could have been high(e.g. 2A),causing the voltage drop for the sensor. This would lead to false sensor reading, till that sensor restablizes.
Has anyone else experienced such preformance or worked on such types of sensors?
