What is Temperature and humidity sensor
Temperature and humidity sensors mostly take the temperature and humidity integrated probe as the temperature measuring element to collect the temperature and humidity signals. After voltage stabilizing and filtering, operation amplification, nonlinear correction, V / I conversion, constant current and reverse protection and other circuit processing, they can be converted into current signals or voltage signals that have a linear relationship with temperature and humidity. They can also be directly output through 485 or 232 interfaces through the main control chip.

Measurement Accuracy
The measurement accuracy is the most important indicator of the humidity sensor. Every increase of one percentage point is a step up or even a grade for the humidity sensor. Because to achieve different accuracy, the manufacturing cost and selling price vary greatly. Therefore, users must tailor their clothes and should not blindly pursue “high, fine and sharp”. If the humidity sensor is used at different temperatures, the influence of temperature drift should also be considered in its indication. As we all know, relative humidity is a function of temperature, which seriously affects the relative humidity in a specified space. Every 0.1 ℃ change in temperature. It will produce a humidity change of 0.5% RH (error). If it is difficult to achieve constant temperature in application occasions, it is inappropriate to put forward too high humidity measurement accuracy. In most cases, if there is no accurate temperature control means, or the measured space is unsealed, ± 5% RH accuracy is sufficient. For the local space requiring accurate control of constant temperature and humidity, or where it is necessary to track and record the change of humidity at any time, the humidity sensor with an accuracy of more than ± 3% RH shall be selected. The requirement of accuracy higher than ± 2% RH may be difficult for the standard humidity generator to calibrate the sensor, not to mention the sensor itself. It is still difficult for the relative humidity measuring instrument to achieve the accuracy of 2% RH even at 20-25 ℃. Generally, the characteristics given in the product data are measured at room temperature (20 ℃ ± 10 ℃) and in clean gas.
Industry demand for Temperature and humidity sensor
Food industry: temperature and humidity are very important for food storage. The change of temperature and humidity will lead to food deterioration and food safety problems. The monitoring of temperature and humidity is conducive to the timely control of relevant personnel.
Greenhouse: the growth of plants has extremely strict requirements for temperature and humidity. Under improper temperature and humidity, plants will stop growing or even die. Using temperature and humidity sensors, together with gas sensors and light sensors, we can form a digital greenhouse temperature and humidity monitoring system to control the relevant parameters in the agricultural greenhouse, so as to achieve the ultimate efficiency of the greenhouse.
Animal breeding: all kinds of animals will show different growth states at different temperatures. The goal of high quality and high yield depends on a suitable environment.
Drug storage: according to relevant national requirements, drug storage must be controlled according to the corresponding temperature and humidity. According to the latest GMP certification, the temperature storage range for general drugs is 0-30 ℃.
Industrial control industry: mainly used for HVAC, machine room monitoring, etc. Environmental control in buildings is usually temperature control. More and more attention is paid to using humidity control to achieve the best comfortable environment.

Genaral Questions About Temperature sensor & Humidity sensor
According to the published international specified tolerance, the common thermocouple is usually ± 2.5 ° C and PRT is ± 0.5 ° C. Higher accuracy sensors can be provided on order, such as ± 0.5 ° C for T-type thermocouple and ± 0.2 ° C for PRT. All these values depend on the temperature. The tight tolerance 4-wire PRT will provide the best absolute accuracy and stability.
Mainly based on the required accuracy, probe size, response speed and process temperature.
No, RTD temperature sensor represents resistance thermometer detector (sensing element), PRT represents platinum resistance thermometer (whole assembly), that is, PRT uses RTD!
Industry standard platinum RTD temperature sensor conforming to iec751 standard, with a value of 100 ohms @ 0 ° C; This is used in the vast majority of PRT components in most countries.
There are several, but these two groups are the most common. Alternatives include thermistors, infrared (non-contact), traditional thermometers (rod and dial types), and many other thermometers.
Use sensors specially designed by Verizon for this purpose or use infrared (non-contact) sensors.
The thin film is deposited on the substrate using platinum; Spiral wound platinum wire in ceramic is used for winding. The winding line provides higher accuracy and stability, but is vulnerable to impact; The film type has impact resistance and Faster thermal response.
Time drift and temperature drift are considered. In actual use, due to the influence of dust, oil stain and harmful gas, the humidity sensor will be aged and the accuracy will be reduced after a long time of use. The annual drift of the electronic humidity sensor is generally about ± 2%, or even higher. In general, the manufacturer will indicate that the effective use time of one calibration is 1 year or 2 years, and re calibration is required upon expiration.
Select the measurement range. As with the measurement of weight and temperature, the selection of humidity sensor must first determine the measurement range. In addition to the meteorological and scientific research departments, those engaged in temperature and humidity measurement and control generally do not need full wet range (0-100% RH) measurement.
