Many people who want to implement the automatic greenhouse greenhouse will have a question, what kind of automatic greenhouse control equipment is needed in the greenhouse? It can be said that no matter what equipment is needed, temperature and humidity sensor should be used as the acquisition tool. Temperature and humidity sensor is the standard equipment for the construction of intelligent greenhouse.

The automatic control system of greenhouse greenhouse is based on the information collected by sensors such as temperature and humidity, soil moisture and soil temperature in the greenhouse, and RS485 bus is used to transmit the temperature and humidity information collected by sensors to signal transducers, which are then transmitted to mobile APP or computer cloud for data monitoring. The sampling data received by the monitoring center will be displayed and stored in the form of a table, and then compared with the alarm value set. If the measured value exceeds the set range, the alarm or voice alarm will be displayed on the screen, and the record will be printed.

At the same time, the monitoring center can issue control instructions to the field controller, and the monitor can control the cooling and dehumidifying operations of fans, pumps and other equipment according to the instructions, so as to ensure the growing environment of crops in the greenhouse. The monitoring center can also activate the sound and light alarm device on the field monitor through the alarm instruction, and inform the greenhouse management to take corresponding measures to ensure the environment in the greenhouse is normal.

In general, temperature and humidity sensor, light sensor and soil sensor are used in front of data acquisition tools. The data is transferred to the temperature and humidity controller, so as to link this set of automatic temperature and humidity monitoring system. The lighting and temperature and humidity are controlled by the final curtain, moving skylight and other devices.

At present, xiamen yingruifeng electronic technology co., LTD has designed a wireless temperature and humidity sensor for agricultural greenhouses. This product does not need external power source, through 2 batteries power supply, reduced installation cost. Its touch button can prevent moisture and water. In addition, RS485 wireless communication interface, stable signal, through a specific router, can transmit the temperature and humidity value collected by the sensor to the terminal of the mobile APP. Through the terminal, the temperature and humidity of the greenhouse and farm can be checked. If the temperature and humidity value exceeds the expected safety value, there will be a corresponding alarm signal. In this case, the user can execute corresponding control instructions to the controller in the greenhouse through the APP, start the fan and water curtain, and timely adjust the temperature and humidity value of the greenhouse.
