Abstract
The invention particularly relates to a temperature and humidity transmitter or recorder detection system which comprises a parameter input module and a temperature and humidity simulation module. The parameter input module receives temperature and humidity data set by a user, converts the data into voltage signals and outputs the voltage signals to the temperature and humidity simulation module, and the temperature and humidity simulation module processes the received voltage signals according to configuration information inputted by the user, and outputs voltage or current or frequency or digital signals to a temperature and humidity transmitter or recorder. By the aid of the temperature and humidity simulation module, the parameters outputted by the user can be converted into corresponding sensor output quantity, and the sensor output quantity is outputted to the temperature and humidity transmitter or recorder, so that the temperature and humidity transmitter or recorder can be quite conveniently detected only by inputting corresponding parameters without building a temperature and humidity test box. Compared with a test box, the temperature and humidity transmitter or recorder detection system with the structure is quite low in cost, quite convenient to assemble and disassemble and small in occupied area.
