| Abstract: | A temperature and humidity acquisition system is designed by using Cortex-M3 as the main controlling chip and DHT11 as the sensor of temperature and humidity, which meets the requirements of low power consumption and costs. TFTLCD is used to display temperature and humidity values. If the collected data is over requirement, a buzzer sends out alarm signal. Experimental results show that the system works stably and reliably with simple circuit. |
