Customized Solution of Temperature and Humidity Acquisition System

1. Product Overview

With the improvement of production technology, environmental temperature indicators have increasingly affected production efficiency, energy consumption and living standards. Whether in the industrial, agricultural, military and meteorological fields, or in the environment of daily life, temperature / humidity needs to be monitored. The ZIGBEE wireless temperature and humidity acquisition system is an emerging short-range, low-power, low-cost wireless communication technology that avoids the traditional problems of using wired connections, cumbersome wiring, poor scalability and portability. Widely used in various fields of industrial control, consumer electronics, family automation, medical monitoring.

1 Function introduction

The ZIGBEE wireless temperature and humidity acquisition system adopts the ZIGBEE star network topology to establish a wireless sensor network of a master node and four slave nodes to realize wireless transmission of data. Each node is connected to a digital temperature sensor DS18B20 to periodically collect the temperature and humidity of the environment , And send the data to the master node in turn through the non-sensing sensor network. After the master node receives the data, it transmits it to the upper recovery PC through the serial port. The host computer stores the collected data in the database, analyzes the data, and monitors it The interface displays the real-time change curve of temperature and humidity. Its functional characteristics:

(1) Ultra-low power consumption: 3 months working with a single battery

(2) Zigbee networking: efficient networking: star network, mash networking

(3) Three-key settings: can set sleep wake-up interval, zigbee parameters, etc

2 Application environment

Wirelessly monitor and record the temperature and humidity of the blood truck, plasma store, fresh store, storage cabinet, refrigerator, freezer, hospital, machine room, drying oven, pharmacy, etc.
