Performance characteristics:

Temperature sensor is a kind of special 18 b20. Single chip microcomputer temperature probe to avoid, for its high precision, calibration of linear temperature/voltage conversion

MCU and V/A conversion of intelligence, the output of the temperature data for sensor board; Motherboard adopts single-chip computer AT89C2051

Processing. And is equipped with upper and lower control. On the sensor of digital visual display; Adjusted by the micro switch, at ordinary times the digital tube display

In the surrounding environment temperature. When the environment temperature more than set point, sensor switch output level signal. Has a high sensitivity.

High accuracy. Calibration. Stable and reliable work, etc.
