Asthma is a common respiratory disease that affects people in many countries. It causes an attack that harms those patients and can cause death. This attack is related to many risk factors, including biosignals and environmental conditions. Here, we provide a dataset (584 entries) on the asthma biosignals and environmental conditions. This dataset was collected from 21 participants who have different levels of asthma disease. It was collected from the Makkah region in Saudi Arabia (Makkah and Jeddah cities) for three months, from 24-march – 30-June 2021.
