The design of wireless monitoring system based on intelligent sensor

Aiming at the flaws of circuit complexity, low accuracy, inconvenience of expansion and maintenance in the traditional multi-point measurement of temperature and humidity using analog circuit, a multi-point temperature and humidity monitoring system based on temperature and humidity sensors SHT11 and wireless transmission circuit is proposed. The features, the internal structure and working principle of SHT11 is introduced; The hardware circuits based on SHT11 and software process of wireless network are designed. It has the advantage of simple circuit, convenience of expansion and maintenance, high accuracy.
