Correct placement position and use method of temperature and humidity recorder

First, the location of the temperature and humidity recorder:

(1) The location of the temperature and humidity recorder is another important factor that affects the measurement accuracy. Because the temperature recorder with built-in sensor can't directly contact the measured object, the position of the immersion sensor is very important for the accuracy of the data.

(2) For a temperature recorder using infrared temperature measurement, the size of the temperature measurement target, the emissivity of the measured substance, the ambient light intensity of the measured object, etc. will also affect the accuracy of the measurement.

(3) The temperature and humidity recorder with external sensor does not have this problem because the external probe can directly contact the measured object. The technical engineer of DLS specially suggested: "We found that some domestic logistics companies put the temperature recorder at the air outlet of the air conditioner of refrigerated trucks, and the data obtained in this way have obvious deviation from the actual temperature of the goods on board, thus affecting the accuracy of the measurement. Therefore, we will generally provide relevant training to customers after purchasing products to help them better use the temperature and humidity recorder.

Second, the use of temperature and humidity recorder:

(1) Whether the temperature and humidity recorder is used correctly or not will also have a direct impact on its accuracy.

(2) Generally speaking, after the temperature and humidity recorder starts to work, it is not immediately possible to read the temperature data with intensive reading, but it takes a certain reaction time to complete the heat exchange with the measured environment.

(3) Generally speaking, the external sensor temperature recorder can reach T90 in 5 minutes. (90% of the measurement accuracy) and the temperature recorder with built-in sensor usually takes 20 minutes to complete this process, so users should put the temperature and humidity recorder into the measured environment in advance, and set a countdown of 5-20 minutes in advance according to the actual situation, so that the temperature and humidity recorder can automatically start at an appropriate time and complete the accurate recording of temperature.

How does the temperature and humidity recorder get the temperature and humidity in a short time?

Smart Internet of Things agriculture is an integrated technology system that applies technologies such as computer and network, Internet of Things and wireless communication to realize the functions of fine management, remote control and disaster early warning of modern agricultural production. Set a temperature and humidity recorder in the greenhouse. During this process, if the humidity in the greenhouse is lower than 20% for a long time, the whole system will give an early warning to the headquarters of the enterprise. The temperature and humidity recorder has launched a "smart greenhouse" construction, and technicians can directly control remotely through computers or mobile phones at home. If it is found that the temperature in the greenhouse has exceeded 35 degrees, the technician can directly turn on the fan in the whole facility shed through mobile phone remote control; When the humidity is lower than 35%, spray irrigation and water replenishment should be started immediately. People can control this piece at any time and any place. The temperature and humidity recorder we developed integrates the Internet of Things temperature sensing technology and network communication technology, which can be used to monitor and manage the temperature and humidity change information in greenhouse in real time, and realize the remote management mode of smart greenhouse.

The temperature and humidity recorder we developed is a temperature and humidity recorder that can record the temperature changes for a long time. The equipment is equipped with a liquid crystal display screen, and the current data can be obtained at any time through the display screen, and the temperature and humidity data display is automatically refreshed every 5 seconds. When the temperature or humidity exceeds the upper and lower limit of the alarm setting, the alarm indicator icon will flash continuously, accompanied by an alarm buzzer; You can also check the power consumption of the recorder through the power display icon on the display screen.
