Description

This application report describes a battery-less operation of a temperature and humidity sensor application. The implementation is done using the SHT21 relative humidity and temperature (RH&T) sensor from Sensirion (http://www.sensirion.com) an MSP430F2274 microcontroller and the TMS37157 (PaLFI) low-frequency device from TI. The complete power for operating the wireless sensor and the MSP430F22
