Example Embodiment

[0033] The present invention will be further explained below in conjunction with the drawings.

[0034] Such as figure 1 As shown by the wireless temperature and humidity intelligent sensor provided by the present invention, there is a wireless temperature and humidity sensor acting as a convergence node in the network that is connected to the upper controller through the RS-232 interface, and other wireless temperature and humidity sensors in the network collect themselves The information is modulated into a wireless ZigBee radio frequency signal and transmitted to the sink node in a multi-hop manner. In the same area, up to 65,535 wireless temperature and humidity smart sensors can work at the same time, forming a huge wireless temperature and humidity sensor system.

[0035] Such as figure 2 As shown in the logical block diagram of the wireless temperature and humidity smart sensor, the microprocessor is the core, the peripheral sensor module and the wired and wireless interf...

The invention is characterized in that the sensor comprises a sensor module, a micro-processor module, a wireless receiving and transmitting module, a serial port communication module and a power module. The core part is the wireless receiving and transmitting module which comprises the following elements: a ZigBee wireless module main chip MC13192, a 16.000MHz crystal oscillator, a radio frequency unit RF transmitting and receiving circuit and a 2.4G PCB double pole antenna. The invention has the following advantages: 1) wireless property; 2) flexibility; 3) low power consumption; and 4) usability.

Description

technical field [0001] The invention relates to a temperature and humidity sensor, in particular to a wireless temperature and humidity intelligent sensor. Background technique [0002] Temperature and humidity are closely related to industrial and agricultural production and people's lives, such as warehouses, farmland, and production processes. Excessive humidity will cause grain mildew and deterioration; temperature changes will affect grain quality; reduce. In addition, with the improvement of people's quality of life, the high requirements for the indoor environment also require real-time monitoring of temperature and humidity. [0003] In the past, most of the temperature and humidity sensors transmitted data by wire, and the circuit redundancy was complicated, which was not suitable for large-scale and large-scale placement. The wiring cost was high, and the aging problem of the circuit also affected its reliability. On the other hand, the wireless technology requir...
