The weak light signal acquisition detection technology based on multi-touch application research

摘要

The system test results show that the system modules can run normally. When light detection circuit, pyroelectric infrared sensor detects information, microcontroller will drive the relay open the light, or shut down. In the window, the motor can work normally, can automatically control the curtain, in the ZigBee information transmission, can to control the power supply and remind. DT11 indoor temperature and humidity sensor detection, can work normally. Through repeated tests, HOLTEK microcontroller based ZigBee smart classroom lighting control system is developed.
