abstract: in many situations, promptly accurately obtains the goalthe temperature, the humidity information is extremely important, thewarm humidity control domain development was in recent years rapid,and along with the digital technology development, the warm humidityobservation and control chip also corresponding mounted historical thestage, could in the industry, the agriculture and so on in variousdomains the widespread use。
In view of this domain development direction, the present paperintroduced take the AT89S52 monolithic integrated circuit as thecontrol unit, temperature sensor DS18B20 and humidity sensor SHT10 isthe primary control component, realizes the multi- spots temperature,the humidity survey, the control and the demonstration。
This design use hardware description language Keil C51 carries on thedesign development, uses mu the VISION2 comprehensive software designprocedure, realizes the electric circuit design request: Thetemperature survey scope is -55 ℃ ~ +120 ℃, in -10 ℃ ~ +85 ℃,precision for ±0, 5 ℃; The humidity survey scope is: 0 ~ 100%RH,the precision is ±4。
5%rh; Can realize in the warm humidity the lowerlimit establishment and the realization refrigeration/heats up (goeswet/adds wet) the control。
Key word: Temperature survey humidity survey sensor monolithicintegrated circuit control meter。
