用单片机实现

可调电阻调节电压值作为模拟温度的输入量，当温度低于30℃时，发出长嘀报警声和光报警，当温度高于60℃时，发出短嘀报警声和光报警。测量的温度范围在0－99℃。 -Adjustable resistance with MCU as the analog voltage regulator input temperature, when the temperature is below 30 ℃, the issue of long beep alarm sound and light alarm when the temperature is higher than 60 ℃, issued a short beep alarm sound and light alarm. Measured temperature range of 0-99 ℃.
