The information we can get, this needs we use the power of science to solve this problem, also because of this, this topic is made. This system mainly adopts single-chip microcomputer controller. Design of the main ideas is through the sensor to monitor the environment temperature, humidity changes and illumination, and will have collected data transmission give monolithic integrated circuit AT89S52 preliminary treatment and then through wireless transmission agreement with custom send control circuits, and in control terminals terminal display on environmental information collected. This thesis mainly by NRF24L01 AT89S52 SCM and wireless transmission module making a monitoring based on DS18B20, HS1101 detection, the temperature and humidity sensor and photoconductive resistance of light intensity, automatic test system for the difference in the monitoring detection can detect nodes directly, monitor, and detects to transmit the current environmental temperature, humidity and light information to the terminal node, with terminal hardware design to co
