In the past two years, the price of pork has continued to rise, which has had a generalized impact on the population. Improving hog farming has also received more attention. How to improve the efficiency of pig farming and realize the intensive, large-scale and high-density development of pig farming is something we need to solve urgently. The environment of pig farms such as temperature, humidity, light, harmful gases, etc. has an important influence on the growth and production performance of pigs. Too high or too low temperature and humidity has a direct impact on the growth rate and farrowing rate of pigs. The use of temperature and humidity transmitters and other automated equipment can effectively monitor the environment of the pig farm. Make pigs grow in an optimal climate environment. Temperature and humidity transmitter in the pig farm application principle has the following points: First: stability. Temperature and humidity transmitter field use is a long-term process, good stability and reliability is the prerequisite for protection, CWS19 temperature and humidity transmitter has a good long-term stability, front-range temperature compensation features. CWS19 temperature and humidity transmitter humidity stability of ± 1% RH FS / year, humidity stability of ± 0.2 ℃ / year. Has good field stability. Second: security. CWS19 temperature and humidity transmitter dust protection level of IP65, there is a good protection performance, so that the temperature and humidity transmitter in the long-term use of the process, free from complex environmental interference. CWS19 temperature and humidity transmitter operating temperature range of -40 ° C to 85 ° C, can be very well suited to the field of use, to ensure that the normal operation of the CWS19 temperature and humidity transmitter. Third: convenience. CWS19 temperature and humidity transmitter has the characteristics of easy installation, not only can be directly wall-mounted installation can also be in the phenomenon of direct rail rail installation, easy to operate. Fourth: practicality. CWS19 temperature and humidity transmitter display for the LCD liquid crystal display, in a poorly lit environment, easy to read, greatly facilitating the use of the user’s feelings. Fourth: advanced. CWS19 temperature and humidity transmitter using high-precision temperature and humidity integrated chip, temperature using diode sensing P-N junction, humidity used for the moisture-sensitive capacitors. And temperature range in the internal circuit board with a temperature range dip switch, through the dial key to switch any of the eight temperature range. Fifth: compatibility. CWS19 temperature and humidity transmitter output signal 4 ~ 20mA current output, 0 ~ 10VDC voltage output and RS485 digital signal output, a variety of signal output, making the transmitter can be better compatible with other equipment systems, easy to use. Sixth: economic. CWS19 temperature and humidity transmitter has the above features and advantages, but also an economic product, the price is only in the hundred dollars or so, is an economical and practical and has good performance of the temperature and humidity transmitter products.   Star Instrument Sensor Manufacturing Co., Ltd. is a collection of research and development, production, sales as one of the high-tech enterprises.
