The Design for Multi-Point Wireless Temperature and Humidity Acquisition USB-Based

Article Preview

Abstract:

Wireless temperature and humidity acquisition system is designed in this paper using PT100 thermal resistances and HS1101 sensors. The system is composed of thermal resistances using C8051f330 microcontroller with two-wire resistance measurement circuits, HS1101 frequency output circuits, 2.4 GHz ISM band RF transceiver chips nRF24L01 with multi-point sending and receiving, combination of wireless communication receiver modules CY7C68013. System uses the USB2.0 send temperature and humidity data to the PC, and display the curves of LabWindows / CVI real-time temperature and humidity.
