Temperature and humidity measurement sensor described in the utility model, liquid-crystal display section, button part, hop, control section all adopt modular design; Demand according to the user is assembled flexibly; Not only can satisfy in the different application the demand of difference in functionality but also can reduce cost to amplitude peak, and simplify the technological process of production.

The refrigeration relay 13 of the RS232 module 8 of the temperature detection chip 2 of described main control singlechip 1, temperature and humidity measurement and data storage, humicap 3, clock chip 6, memory chip 7, the Liquid Crystal Module 4 that shows, button 5, hop, RS485 module 9, radio-frequency module 10, ethernet module 11, SMS module 12, control section, add electrothermal relay 14, dehumidifying relay 15 and humidification relay 16 and be commercially available common components.

The advantage of the utility model is:

1, complete function; Transmission mode is various; Comprise warm and humid measurement, demonstration, real-time humiture data recording, the data transfer mode of number of ways; And can receive various settings, the operational order of host computer, the equipment of the refrigeration heating of relative influence humiture, dehumidifying humidification is carried out intellectuality automatically control.

2, each functional module all is modular design, according to final user's demand, carries out the combine and assemble of difference in functionality module, can meet the different needs, and cost is low again.

3, can with host computer networking work, also can independently become the device of a temperature and humidity measurement, warning, control through the button operation setting.
