This letter describes a developed wireless sensor network based on a proposed algorithm for monitoring the environmentalparameters in healthcare intentions. This proposed algorithm contains a frame with diff erent packets that are implemented onthe developed wireless sensor network. The developed wireless sensor network consists of one central node as well as foursensor node that has been equipped with various sensors such as temperature, humidity, CO, CO 2 , and passive infrared sensor. In order to test the presented algorithm and the developed wireless sensor network, the sensor nodes are situated in fourdiff erent rooms in a hospital for recording essential parameters of the environment while the central node is put in the nursestation for warning to nurses. The obtained result of the proposed sensor nodes in comparison to gold standards shows rootmean square error 1.1%, 0 .35 ◦C , 0.98% for humidity, temperature and gas, respectively. Also, the obtained results illustratethat the system gives accurate feedback from environmental temperature, humidity, and CO, and CO 2 to the nurse station inorder to increases the possibility of a healthy environment condition for patients.
