The temperature sensor chip used in the temperature and humidity detector in the computer room

In computer equipment, a large number of semiconductor devices, resistors, capacitors, etc. are used. When computers are powered on, the increase in ambient temperature will affect their normal work. The temperature in the computer room is too high, the heat dissipation of the machine is not smooth, and the working parameters of the transistor will drift, which will affect the stability and reliability of the circuit, and even cause the breakdown and damage of components in severe cases. Excessive humidity can easily cause corrosion of metal parts and connector tube parts of the equipment, and reduce the insulation of circuit boards, connectors and wiring, which can seriously lead to short circuits; if the air is too dry, it is easy to cause electrostatic effects and threaten the safety of communication equipment .

The temperature and humidity monitoring of the computer room is one of the important tasks of the operation and maintenance department of the operator, and the temperature control system is the nerve center of the temperature and humidity control of the computer room. When monitoring the temperature and humidity, it is necessary to ensure that the computer room is in a suitable environment to make the computer room more stable.
In fact, the country promulgated relevant standards as early as 1989, and in 2011, it perfected the recommended standards for temperature and humidity in the relevant environment. The standard divides computer rooms into three categories, ABC, and category A has higher requirements.
Temperature and humidity requirements when starting up:
A-level computer room: summer temperature is 24±1°C, winter 20±1°C, relative humidity 40%~60%RH, temperature change rate <5°C/h B-level computer room: summer temperature is 24±
2 ℃ in winter 20±2℃, relative humidity 35%~65%RH, temperature change rate <10℃/h
C-level computer room: temperature between 15 _{and 28°C, relative humidity 30%} 80%RH, temperature change rate<15℃/h The temperature and humidity requirements when
shutting down:
A, B, and C grade computer rooms have a temperature between 5°C and 40°C, and a relative humidity _{between 20%} and 80%.

The installation of the detection element should ensure the correctness of the measurement, and choose a representative installation position. For contact temperature measuring elements, the detection element should have sufficient insertion depth, and should not be inserted into the dead corner of the medium, so as to ensure sufficient heat exchange between the detection element and the measured medium, and measure the medium in the pipeline. When the temperature is high, the working end of the detection element is located in the center of the pipeline where the flow rate is relatively high. The detection element should be installed facing the flow direction of the fluid. If it is unavoidable, do not install it along the flow of the measured medium, otherwise measurement errors will easily occur; measure negative pressure The temperature of the pipeline (or on the equipment) must be sealed to prevent the suction of outside air and reduce the accuracy.
