Temperature control for server room \r\n\r\nTemperature control is a device for measuring temperature or timely control of temperature so that it does not go out of the allowed range. This factor can be considered important for places such as server room - electrical room - UPS room - telecommunication room, therefore resorting to a device for temperature control or monitoring is very important. \r\n\r\nBut an important issue that is not given importance at times is how reliable these equipments that we receive for monitoring and recording temperature reports and warning notifications are, in other words, can these equipments be trusted in real critical situations at all times. \r\n\r\nIf the server room control system accidentally sends us an alarm in real working conditions, can we really trust that system anymore, or will we stop trusting it since that happened? This is a problem that occurs frequently in some server room temperature control systems, and it is unbelievable for the buyers and managers of the server room. \r\n\r\nTo avoid facing this issue, the only method is to carefully check the companies that claim to make or sell server room temperature control systems. This check can include things including: \r\n1- Has the providing company obtained the satisfaction of its customers in previous sales? \r\n2-Does this company work in the field of precision instrument control? \r\n3- Is the Hood company a manufacturer or by assembling the equipment, sometimes China has placed itself among the manufacturers \r\n4- Is the hardware used industrial? \r\n5-Is the system architecture derived from an acceptable architecture? \r\n6- Have false alarms ever been seen on this hardware? \r\n\r\nThese cases and some other questions in this direction can to some extent remove the heavy burden of choosing the company providing the product from the shoulders of the server room manager, but it cannot remove this burden. \r\n\r\nBut the server room temperature control systems can also monitor other sensors, such as: \r\n1) Temperature rise sensor\r\n2) Humidity increase sensor\r\n3) Mains power cut sensor\r\n4) UPS disconnection sensor\r\n5) smoke increase sensor\r\n6) Water leak sensor\r\n7) The sensor for the door of the server room to remain open\r\n8) Unauthorized entry sensor to the server room\r\n9) Rack impact sensor\r\n10) Power fluctuation sensor\r\n11) Rack temperature increase sensor\r\n12) The sensor for increasing the temperature of the spilt or the sensor for the failure of the cooler\r\n13) Battery discharge sensor\r\n14) Rack door opening sensor\r\n15) Cooler compressor burning sensor\r\n16) condenser freezing sensor\r\n17) Cooler fuse break sensor\r\n18) Warning of sensors not working properly\r\n19) Fire presence sensor\r\n20) Ignition prevention sensor\r\n21) Zero wire charging sensor\r\n22) network biphasing sensor\r\n23) dust increase sensor\r\n24) Refrigeration system gas exit sensor\r\n25) The sensor increases or decreases the network voltage from the allowed range\r\n26) earth fault relay\r\n27) Hydrogen gas emission sensor in the battery bank\r\n28) Absence sensor k
