This design adopts the CC2530 chip (one type of ZigBee chips) produced by TI Company as both master chip and communication chip, and the Platinum Resistance PT100 is used as the temperature sensor. The programing of collection, transmission, and management software is based on the Z Stack of TI company, to realize the temperature acquisition and wireless transmission. Meanwhile, the hardware circuits and software programs take full account of the low power and high reliability design. The entire temperature sensor is powered by a lithium battery, which can be charged by a solar panel, and can be used independently in a outdoor environment for a long time.
