An instrument called a temperature sensor is made to gauge how hot or chilly an object is. The voltage applied across the diode determines how well a temperature metre functions.
The resistance of the diode is exactly proportional to the temperature change. Resistance decreases with decreasing temperature and vice versa.
Temperature readings in readable measures (such as Fahrenheit, Celsius, Centigrade, etc.) are calculated from the resistance across the diode and are then shown numerically over readout units.
These temperature sensors are employed in the geotechnical monitoring sector to gauge the internal temperatures of many types of structures, including bridges, dams, buildings, power plants, etc.
The Global PWM Temperature Sensor market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
The TC648 and NTC sensors are used in a PWM temperature-controlled fan. Pulse width modulation is used to adjust the temperature proportionally (PWM). The temperature is sensed using a 10K Ohm NTC.
The TC648 chip was used in the project’s construction, and auto-shutdown mode was set up. When the detected temperature falls below 25 degrees Celsius when in Auto-Shutdown mode, fan operation is automatically stopped.
When the temperature rises above 25 degrees Celsius, the fan restarts itself and proportional speed control is reinstated. When turning on or exiting shutdown mode, an incorporated Start-Up Timer assures a stable motor start-up. The MOSFET Q1 is available to drive the fan at a maximum load of 3A. Some fans need a PWM signal to function.
