The Exhaust system for air ventilation in hospital emergency facility which we want to work remotely with gas sensors https://store.ncd.io/product/mq-7-carbon-monoxide-gas-sensor-adc121c-12-bit-adc-i2c-mini-module/ and analyze all the data and share it on Azure cloud as per the IOT solutions which I found out through internet.
The gas sensors are easy to interface with raspberry pi but I have never worked with online servers to send data of these sensor to cloud's database, for which I need some good suggestion which will help to send the data of sensors to cloud without any problem.

 

Microsoft has published quite a few documents, including code samples outlining how to do what you are looking to do. Some include Raspberry Pi as well as Arduino. Several platforms are also covered. Since Azure Cloud is a Microsoft product I would first look at their suggestions and documentation and decide what best suits your needs. Here is an example using Raspberry Pi.
