The Blynk platform is utilized for seamless communication between the user interface and the IoT device. The chips/modules are only sensitive to light modulated with a specific carrier frequency. I decided to implement three control modes. When the photoresistor detects that the room brightness is too bright, Raspberry Pi will drive the motor to close the curtain; when the room brightness is too.

DTS temperature measurement system detection optical cable
Distributed Temperature Sensing (DTS) systems provide temperature information for accurate thermal monitoring, fire detection, and condition assessment by utilizing standard fiber optic cables. Temperatures are recorded along the optical sensor cable, thus not at points, but as a continuous profile. Unlike traditional electrical temperature measurement (thermocouples & RTD), the length of the fiber optic cable is the temperature. In distributed temperature sensing (DTS), a single fiber optic cable measures temperature at thousands of points. Our group found its application also possible in environmental sensing.
