Abstract
A single chip wireless sensor () comprises a microcontroller () connected by a transmit/receive interface () to a wireless antenna (). The microcontroller () is also connected to an 8 kB RAM (), a USB interface (), an RS232 interface (), 64 kB flash memory (), and a 32 kHz crystal (). The device () senses humidity and temperature, and a humidity sensor () is connected by an 18 bit ΣΔ A-to-D converter () to the microcontroller () and a temperature sensor () is connected by a 12 bit SAR A-to-D converter () to the microcontroller (). The device () is an integrated chip manufactured in a single process in which both the electronics and sensor components are manufactured using standard CMOS processing techniques, applied to achieve both electronic and sensing components in an integrated process.
