Application of Leaf Humidity Sensor in Plant Greenhouse Control System
Thrust Spherical Plain Bearings have a convex spherical surface on the shaft washer and a corresponding concave spherical surface in the housing washer. They are intended to accommodate primarily axial loads but can also accommodate combined (radial and axial) loads. The radial load component of a combined load should not exceed 50% of the axial load component. When radial loads are larger, it is advisable to combine thrust bearings with radial bearings in the GE dimension series . Thrust spherical Plain Bearings are separable, e.g. shaft and housing washers can be mounted separately.

The function of the sensor subsystem is to convert climate parameters into voltage parameters. It is the main source of information for the monitoring system and relates to the reliability and accuracy of the entire system for detection, data analysis, and control. Mainly include soil moisture sensor, leaf surface humidity sensor, air temperature and humidity integration sensor, light intensity sensor, CO2 sensor. Due to the large area of ​​the greenhouse, the sensor is a fixed-point instrument, so the use of various types of sensors is large.
Real-time data collection and processing of leaf surface humidity sensors. In order to ensure real-time detection of environmental changes in the greenhouse, data collection and processing must meet certain time limits so that they can be processed in real time to resist accidents. Most of the functions of the system are realized by software. Since the peripheral circuit is simple, the software can be modified at any time, so the adaptability is strong. The operator can change the preset parameters of the environment according to the habits and growth characteristics of the plants in the greenhouse and ensure the plant growth environment. optimal.
Thrust spherical plain bearings with the maintenance-free steel/ PTFE FRP (fibre reinforced polymer containing PTFE) sliding contact surface combination as standard. Other sliding surface combinations are available on request (Special designs).
