Objective:Temperature and humidity impacted on blood, biologics and medicine preservation. So temperature and humidity monitoring system based on 433MHz frequency wireless, Ad Hoc sensor network, was significant for it. System Proposed two key algorithms to solve wireless communication problem. Monitoring terminal and MCU constituted master-slave control system, that could monitor, record and analysis temperature and humidity the whole day. The test result by number of medical units showed that this temperature and humidity monitoring system has high precision, low failure rate, 99%accurate alarm rate and 96.5%data transmission integrity.
