Abstract

The system with STC89C52 RC MCU as control core uses nRF905 chip as the wireless transmission module,signal acquisition and humidity sensor HS1100 /HS1101,and this paper designs a wireless storage humidity detector. The experimental result shows that the range of the system for humidity detection: 10% RH ~ 100% RH; the accuracy of detection ± 1% RH; the transmission distance of data wireless: 200 meters. The design of the system meets the expected requirements,it can be applied to in some situations that are uneasy to wire in and need to be monitored for real-time moisture parameters,such as: daily management,meteorological phenomena and winery for storage.
