Design of Multi-sensor Human Environment Monitoring Equipment

Abstract

In order to meet the patient's daily monitoring needs, in view of the problems existing in monitoring equipment at home and abroad, such as the single sensing parameter, the loss of data association and 433Mhz, ZigBee and other short wave communication modes are limited by the transmission distance, high power consumption, etc. It uses IEEE 802.11 WIFI transmission protocol, directly connected with the Internet. It integrates a number of high-precision sensors, such as light intensity, temperature, humidity, magnetic field, acceleration, vibration, etc., which can be used to monitor the activities of the environment data in a multi-dimensional way. The experiments show that the real-time, event correlation and reliability of the data are verified. Families and doctors can fully monitor the patient through mobile phones and PC side data, call the police in case of emergency, and the minimum power consumption can reach 59uA.
