Temperature and humidity sensor applications in environmental monitoring

Metro 's large volume, which is a large passenger flow , the required variation in fresh air . Therefore subway air conditioning load changes, to achieve energy must resort to automatic control means. Automatic control system as an integral part of , environmental sensors in the subway more plays an important role . The environmental control system in the subway , the main use of the indoor temperature sensor and humidity sensor , duct temperature and humidity sensors . We can order at the station concourse and platform areas and other public areas as well as important equipment room set indoor temperature and humidity sensors to monitor real-time temperature and humidity of the station . These parameters can help operational staff working conditions of various systems of the station to make reasonable adjustments to keep always in the public areas of the station more comfortable environment to ensure that the device has been in the right room temperature under . Indoor temperature and humidity Car Sensors are generally mounted on the station concourse , platform and equipment room on the wall or on top . In the meantime, we can at the station 's new air chamber and the return air duct temperature and humidity chamber mounted Engine Water Temperature Sensor to monitor the outdoor air and the temperature and humidity inside the station . Environmental control system according to the data collected by sensors to determine the environmental quality of the station , and according to a variety of conditions pre-designed for automatic switch , automatic control system in order to achieve automatic control of the environment of the station , so that the station is always in a more environment comfortable environment, and ultimately achieve the purpose of energy saving and emission reduction . Pipeline temperature and humidity Coolant Temperature Sensor is usually installed in the new and the return air plenum chamber walls. Thus, the temperature and humidity sensor usefulness in life more and more, it is not only in the station , greenhouse , file management and food industry has applied , is now in the subway environmental control system has also been adopted .
