This topic is the temperature alarm's design. The temperature monitoring system design and development mainly uses single chip computer and sensor technology.
Software development using C language as a development tool. The design of the hardware circuit with STC12C5616AD single chip computer and AD590 temperature sensor. STC12C5616AD is the main control device, and the function of the s temperature measuring achieve through the AD590 temperature sensor change temperature to electric.
This system can realize the alarm limit setting, temperature shows, voice alarm function. It’s a kind of easy to use, simple structure, cheap price,stable performance, intelligent temperature alarm. Temperature alarm has good application prospects.
