Temperature and Humidity Wireless Sensor System based on Bluetooth Low Energy and Solar Self-power

Abstract

Abstract According to the actual needs of the modern greenhouse, this paper designs a low-energy solar self-powered temperature and humidity wireless sensor system based on Bluetooth low energy. The system uses a Panasonic AM-1801 solar panel and S6AE103A single-chip microcomputer as the energy management module to realize the self-power supply of the system, and uses Si7202-A20-IM1 as the sensor module to collect the temperature and humidity in the environment. The monitoring data are transmitted through the Bluetooth wireless network. The receiving end of the upper computer uses the CY8C5868LTI-LP039 module USB Dongle to receive data. The system realizes the wireless data transmission of the temperature and humidity sensor in the greenhouse environment and the real-time network monitoring of the ambient temperature and humidity through the Bluetooth network. This system can be applied to various greenhouse systems.
