Intelligent Agriculture for Internet of things applications-Gas temperature and humidity Sensor

Sensor is widely used in agricultural production. It can be used in every link of agricultural production. In recent years, with the increase of domestic investment in agricultural science and technology and the in-depth development of the strategy of developing agriculture through science and technology, Sensors have a wide application market in agriculture. The use of temperature and humidity sensors in greenhouses can promote plant growth. The temperature and humidity sensor is an important part of the intelligent environment monitoring system for agriculture in the Internet of things. When the greenhouse monitoring system is installed, the operator can operate the heating and ventilation equipment inside the greenhouse according to the real-time temperature and humidity data of the temperature and humidity sensor. It can effectively solve the disadvantages of high operating cost and large energy consumption in modern intelligent multi-span greenhouses. The monitoring system can also set alarm values according to vegetable growth conditions and alert staff when temperature and humidity are abnormal.

The temperature and humidity sensor is one of the sensors. It monitors the air temperature and humidity in real time, after measuring the temperature and humidity, it is transformed into electrical signal or other necessary information output according to certain rules. Temperature and humidity sensor plays an important role in agricultural production.

Air temperature and humidity sensor:  the humidity sensor adopts the imported thin film humidity sensor as the inductive component. It has the characteristics of high measuring precision and good stability. The signal transmitter adopts advanced circuit integration module. According to the different needs of the user, the humidity can be converted into the corresponding voltage or current signal. The instrument is compact, convenient to install and portable, and reliable in performance.

Functions and advantages of air temperature and humidity sensor

1. The set of multiple wireless sensors can be used for multi-parameter cooperative monitoring among nodes, and the output signal has good linearity and strong anti-jamming ability.
2. It has the ability of calculation and storage, and can be monitored according to the change of environment.
3. Small size, easy to disassemble and easy to install.
4. Fast response speed, high precision, wide measuring range and good stability.
5. In addition to the system display can also be in the scene to view the data, convenient and fast.
6. Can prevent direct sunlight into local temperature deviation and Rain Water's scour.
7. Low power design increases system monitoring and protection measures.
8. Indoor and outdoor use.

Precautions for temperature and humidity sensors:

1. The sensor itself is not waterproof, so do not soak the sensor in water.
2. Sensor is a precision device, users should not remove themselves, with sharp or corrosive liquid contact sensor surface, so as not to damage the product.
3. Sensor cable shield layer has been short-circuited with ground wire, please handle the shield wire properly when connecting.
4. In selecting the temperature and humidity sensor, we should pay attention to the range of measurement and the choice of measuring precision, and also take into account the key factors such as time drift and 5. 5. 5. temperature drift. In addition, the humidity sensor is unsealed to protect the accuracy and stability of the measurement. Use in acidic, alkaline and organic solvents should be avoided as far as possible.

The temperature and humidity sensor can be used in greenhouse, tea mountain management, orchard management, edible fungus cultivation, livestock breeding, field planting, aquaculture, ecological agriculture, big data agriculture, leisure agriculture, Food safety traceability and other agriculture, forestry, animal husbandry and fisheries related industries are essential intelligent devices in agricultural Internet of things solutions.
