In agriculture, water spraying is the only way. In the new application of Internet + modern agriculture, farmers can use sensors to "communicate" with crops and realize precision production through the Internet of things.
Air in the greenhouse of Dendrobium candidum base in Changling Village Temperature and humidity sensor 。
In Changling village, Xiaolou Town, Yuexiu District, Guangzhou, villagers can manage the Dendrobium officinale planted by them with mobile phones, spray water, start the fan to cool down, supply on demand, and remotely monitor the growth status and environmental status of Dendrobium officinale without being on site.
Dendrobium temperature sensor in the greenhouse.
In the Dendrobium officinale base at No. 1, Dachang, Changling village, Xiaolou Town, there is a greenhouse of about 200 square meters, which is planted with Internet of things technology. Compared with ordinary greenhouses, the Internet of things technology greenhouse is equipped with distribution box, soil temperature and humidity sensor, air temperature and humidity sensor, sprinkler head, fan and 360 degree rotating camera.
According to the technical personnel in charge of the village's Agricultural Internet of things service, the Agricultural Internet of things means that in the greenhouse control system, the advanced Internet of things data acquisition, video detection and control system are used to realize the real-time monitoring of greenhouse temperature, moisture and light, and the collected data are transmitted to Internet computers or mobile phones. Through the mobile terminal, agricultural technicians can control the greenhouse crops remotely, and the technicians can monitor and control the greenhouse environment and crop growth in the office.
Technical personnel guide Wang Chengzhi to use the intelligent management system of the Internet of things.
In December 2016, local villager Wang Chengzhi started to use the Internet of things to plant Dendrobium officinale. Through computers and mobile phone terminals, the temperature and humidity of air and soil can be monitored in real time and accurately, and then automatically operated and managed according to the preset expert scheme. Wang Chengzhi only needs to press a switch on his mobile phone, make a choice, or listen to "instructions" completely, which can provide an optimal growth environment for Dendrobium officinale.
According to Dendrobium, the humidity of the soil is very important. For example, water should be frequently sprayed and less drenched, and the air humidity should be kept at 60% - 80%. Especially in spring and summer, the frequency of spraying and ventilation should be high to ensure the growth environment of Dendrobium officinale to reach the optimal state.
Through the mobile phone terminal, Wang Chengzhi can manage Dendrobium officinale.
When the air temperature and humidity, soil temperature and humidity and other parameters in the greenhouse are too low or too high, the system will automatically remind them. He will click the relevant command box of the intelligent control module and open the switch valve of the sprinkler head and fan to realize the temperature control of spraying and circulating ventilation. Wang Chengzhi said that even if people are not in the greenhouse, they can take good care of Dendrobium officinale, and he is much more relaxed.
