Description: ■ basic range-55 ℃-125 ℃
■ precision of less than 0.5 ℃
■ LED display digital direct-reading temperature higher than 35 ℃
■ start cooling fan, the fan stops lower than 34 ℃
■ temperature can be arbitrarily set the upper and lower alarm program
Taking into account the temperature sensor, the microcontroller circuit design, most are using the sensor, so it is very easy to think, and temperature sensor with digital and analog of the points, but more convenient to use digital temperature sensor directly, it can use digital temperature sensor DS18B20, this sensor can be easily read directly measured temperature, conversion and digital temperature measurements directly, it can meet the design requirements.
