利用温度传感器将现场采集温度通过无线红外传送到2米以外距离进行显示监控，显示精度优于1°计红外收发系统由温度采集、发射和接收三大模块组成。通过DS18B20采集的温度信号，通过红外发射管发射到接收端并在数码管上显示，在接收端通过HS1838接收并输出已调红外信号，通过数码管显示，最后对比两端数码管显示出的温度值是否一致。这些是详细的程序方案-Temperature sensor temperature field data via wireless infrared transmission to two meters away from the display monitor, display accuracy of better than 1 meter the temperature acquisition infrared transceiver system by transmitting and receiving three modules. DS18B20 collecting temperature signals, via infrared transmitter tube is transmitted to the receiving end and is displayed in the digital tube receives and outputs the infrared signal modulated by the digital display at the receiving end through HS1838 digital tube at both ends of the final comparison shows that the temperature of the values ​ ​ are consistent.
