The temperature and humidity sensor is by far the most widely distributed sensor in the agricultural application field

With the continuous progress of modern society, the production and development mode of traditional agriculture can no longer keep up with the needs of modern civilization. Sensors with different functions are gradually applied in the production and development of the world, with only one purpose, to improve the output and quality, increase the economy, improve the ecological environment, and ensure sustainable land production.
With the help of sensors, we can grasp the natural factors that affect agricultural production at any time, realize remote control, and effectively reduce human consumption. Through scientific data analysis, we can improve the ability of the whole agriculture to resist disasters and risks, thus increasing the productivity of agricultural products.
The emergence of sensors has also led agriculture to a path of intelligent, standardized and remote control. Among all the sensors, there are always hot “stars” that often appear in people’s eyes. Now, let’s introduce what kinds of sensors are there!
Temperature and humidity sensor:
Temperature and humidity sensors are by far the most widely distributed type of sensors in agricultural applications. Whether it is greenhouse planting, soil temperature monitoring, or outdoor planting, temperature and humidity sensors are required. If the LORA wireless temperature and humidity sensor is installed in the crop growth environment, it can monitor the temperature and humidity changes in the crop growth environment in real time, while the soil temperature and humidity sensor is usually installed in the root soil of the crop, which can be installed in different locations according to the root state of the crop. It can monitor the changes of water and temperature in the soil during the growth and development of the crop, and provide reliable data to managers, Let it be watered in time.
Light sensor:
In agricultural production, sufficient light can help crops grow rapidly, while the light sensor used in agriculture has high sensitivity to weak light, and will have the advantages of small size, convenient installation, good waterproof performance, wide measuring distance, long transmission distance, etc. Especially in the greenhouse, the light intensity required for monitoring crop growth is very suitable.
Carbon dioxide sensor:
The wireless carbon dioxide transmitter, which uses wireless spread spectrum technology, has strong penetration ability. In indoor applications, it can penetrate 3-4 concrete walls. In open areas, the measuring range of a device can reach 800 meters, without spending time and money to lay cables. The wireless carbon dioxide transmitter is mainly used in greenhouse or flower breeding, ecological industrial park and other places that need to monitor carbon dioxide but do not want to lay cables, By monitoring and regulating the carbon dioxide gas, the concentration of carbon dioxide required for indoor plant photosynthesis can be guaranteed.
However, with so many agricultural related sensors on the market, how should we make a choice? First of all, for agricultural personnel, the cost is the most important, while agriculture is generally carried out outdoors, and the power supply is blocked, so it is best to choose sensors with low power consumption. The protective enclosure of the sensor for outdoor use must be selected with a protection level of IP65 or above. The protection level below IP65 is not suitable for outdoor agriculture. And the material used must be corrosion resistant, not ordinary plastic material, or the service life of the sensor will be greatly reduced after long-term outdoor exposure to the sun and rain.
For agricultural personnel, the simpler the use method is, the more convenient the maintenance steps are. Many agricultural personnel are not technicians. Due to their limited knowledge on the use and maintenance of sensors, the wiring and installation of the selected sensors should not be too complex. In this way, even if there is any problem in the use process, agricultural personnel can simply check and deal with it, greatly reducing the maintenance cost. For agricultural personnel with limited production and budget, sensors with the same price should be selected with good stability and repeatability.
