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 key algorithms to solve wireless communication problem: sensor terminal and management host directly or indirectly communicate by 433MHz RF algorithm. Monitoring terminal and MCU constituted master-slave control system that could monitor, record and analysis temperature and humidity the whole day. System had Local alarm and SMS alarm function once data overran. The test result by number of medical units shows temperature and humidity monitoring system has high precision, low failure rate, 95.4% accurate alarm rate and 93.5%data transmission integrity.
