The temperature and humidity controller is the core part of the temperature and humidity monitoring system . If we just want to implement the data monitoring function, then we don't need to use the temperature and humidity controller in the system; if we want to automatically control the monitored parameters The equipment automatically adjusts the environment in the greenhouse. In a simple system, the temperature and humidity controller can easily do it.
The temperature and humidity controller produced by Chengdu Xinxin Electronic Technology Co., Ltd. has complete functions. It is an intelligent controller integrating temperature and humidity acquisition and control. Our temperature and humidity controller supports a variety of temperature and humidity sensors . And our temperature and humidity controller provides four passive relay switch output and RS485 communication interface. The four relay passive switch output corresponds to the temperature upper limit, the lower temperature limit, the upper humidity limit, and the lower humidity limit. Alarm Output. The RS485 communication interface is used to build a temperature and humidity acquisition system, which is convenient for communication with a host computer (PC). It uses the powerful database and data processing and query capabilities of the host computer to provide users with more convenient and powerful functions, such as historical data query, export printing, public Internet access, SMS alarm, etc.
For example: The temperature and humidity controller developed by Xinxin Electronic Technology Co., Ltd. can be based on the upper and lower limits of the parameter values set by the user on the controller, and then the data obtained by the sensor is compared with the data set by the user. If the collected data is greater than the temperature and humidity set values on the controller, the controller will trigger the power supply of the exhaust fan to make the fan run to reduce the temperature and humidity. When the temperature and humidity are lower than the set When the parameter lower limit is reached, the controller disconnects its circuit and the fan stops working. If the monitored humidity value exceeds the lower limit, the controller will control the humidification device to turn on to increase its humidity. When the humidity value is higher than the set value, the controller controls the humidification device to disconnect and stop humidification.
The temperature and humidity controller is widely used in high and low voltage switch cabinets, breeding, hatching, vegetable greenhouses, and other places that have strict requirements on temperature and humidity.
