Hi Sudipta, I have already worked with the electrospinning process, I recommend to you use a nitrogen enviroment (use a sensor too), but that is difficult, because you need a fully enclosed chamber, and normally the machine of electrospinning does not have this. I think that, if your humidity is not a very important parameter for your experimental work, you can depreciate.

Hello Sudipta,

You can use a humidity sensor and a humidifier/fogger used in agricultural applications. Then use a controller that controls this humidifier so that the humidity value stays within the limit that you want. Or even a simpler experiment could be to use the humidity sensor with standard analog output and manually monitor the values using any low-cost digital multimeter and adjust the humidifier to maintain the level that you want. You can try this and see how it works for you.

Best wishes!

Hi Sudipta,

for humidity control you should use a DHT11 sensor, simply Arduino controlled. It's low cost, miniaturized and fast time response.

Good luck
