Temperature and humidity control of the intelligent greenhouse is an important link of monitoring. This paper uses Surplus 16-bit single chip microcomputer as the core control of the system. Combined with wireless transceiver chip NRF401, USB interface device PDIUSBD12 and temperature and humidity module YXHT300U, we designed a wireless temperature and humidity monitoring system which used in intelligent...
The application of distributed controlling system which used in the measurement of temperature and humidity is studied in this paper. Its emphasis is the methods of principle & application which centralized a kind of intelligent controller microcomputer AT89C51. The system here can realize many functions, such as temperature & humidity's measurement, displaying and alarm; the regulating and...
System selects temperature sensor DS18B20 and humidity sensor HS1101 to compose sensor groups after analyzing avian hatching requirement, which realizes temperature and humidity automatic monitor and control through 1-wire bus technology. Sensor groups complete field hatching temperature/ humidity monitor and transmit analog signal into digital signal, single chip microprocessor (SCM) AT89C51 as core...
