Wireless temperature and humidity sensor for agriculture greenhouses

Many people want to implement automated greenhouses with such a question. What kind of greenhouse automation control equipment is needed in the greenhouse? It can be said that no matter what equipment is required to use the temperature and humidity sensor as a collection tool, the temperature and humidity sensor is a standard for the greenhouse construction of smart greenhouses.

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

At the same time, the monitoring center can issue control instructions to the field controllers. The monitor controls the fans, pumps, and other equipment to perform cooling and dehumidification operations according to instructions to ensure the growth environment of the crops in the greenhouse. The monitoring center may also initiate an audible and visual alarm device on the on-site monitor by means of an alarm instruction to notify the greenhouse management personnel to take appropriate measures to ensure that the environment in the greenhouse is normal.

In general, the front-end data acquisition tools such as temperature and humidity sensors, light sensors, and soil sensors are used. The data is transmitted to the temperature and humidity controller to link with this set of automatic temperature and humidity monitoring system, through the final roller blinds, mobile sunroof and other equipment to control the light and temperature and humidity.

At present, Xiamen Yingruifeng Electronic Technology Co., Ltd. designed a wireless temperature and humidity sensor for agricultural greenhouses. This product requires no external power supply and is powered by two batteries, reducing installation costs. Its touch button can prevent moisture and water. In addition, RS485 wireless communication interface, signal stability, through a specific router, the temperature and humidity values ​​collected by the sensor can be transmitted to the mobile phone APP terminal. Through the terminal, you can view the greenhouse and farm temperature and humidity values. If the value of temperature and humidity exceeds the safe value of the expected setting, there will be a corresponding alarm signal. In this case, the user can execute the corresponding control instruction to the controller in the greenhouse through the APP, start the fan, curtain, and timely adjust the temperature and humidity values ​​in the greenhouse.
