The Crowbits-IR Temperature Sensor refers to a sensor that can sense the temperature and convert it into a usable output signal.
The physical nature of the infrared radiation is thermal radiation, The physical essence of infrared radiation is thermal radiation. As long as there is any object whose temperature exceeds 0 degrees, it will emit radiation. The more violently molecules and atoms move, the more energy they radiate, On the contrary, the smaller the radiation energy is, the infrared radiation energy of an object and its distribution by wavelength is closely related to its surface temperature. The infrared radiation detector reflects the power signal of the object radiation back to the sensor and converts it into an electrical signal, which can accurately determine its surface temperature.
Connect the temperature sensor module to A4 and A5 ports of UNO, turn on the respective program, and downloaded to the control board, open the serial port, and observe the corresponding results. Check the measured temperature, which is close to the current room temperature, and allow an error of plus or minus 1 degree.
