摘要
基于ds18b20温度传感器具有体积小、硬件开销低、抗干扰能力强、精度高等优点。采用STC89S52单片机为控制核心,利用DS18B20温度传感器采集大棚温度数据,经单片机处理后在lcd1602液晶上显示,设计一种大棚温度监控电路。可以实现大棚温度的采集、温度控制和报警提示的功能。解决了温室大棚人工控制的准确度不高、费时费力等问题。
The ds18b20 temperature sensor has the advantages of low volume, low hardware cost, strong anti-jamming capability and high precision. Using STC89S52 microcontroller as the control core, the use of data collection and canopy temperature DS18B20 temperature sensor, the SCM processing on the lcd1602 LCD display, design a kind of greenhouse temperature monitoring circuit. The function of collecting temperature, temperature control and alarm prompt can be achieved. The problem of low accuracy, time and effort is solved.
