The temperature and humidity acquisition system can be used for agricultural and medical monitoring
Customized scheme of temperature and humidity acquisition system
1、 Product overview
With the improvement of production technology, environmental temperature index has more and more impact on production efficiency, energy consumption and living standards. Whether in industrial, agricultural, military, meteorological fields or daily living environment, temperature / humidity monitoring is required. ZigBee wireless temperature and humidity acquisition system is a new wireless communication technology with short distance, low power consumption and low cost, which avoids the problems of traditional wired connection, cumbersome wiring, poor scalability and portability. It is widely used in industrial control, consumer electronics, family automation and medical monitoring.
1 function introduction
ZigBee wireless temperature and humidity acquisition system adopts ZigBee star network topology to establish a wireless sensor network with one master node and four slave nodes to realize wireless data transmission. Each node is connected with digital temperature sensor DS18B20 to regularly collect the temperature and humidity of the environment, and send the data to the master node in turn through the senseless sensor network, After receiving the data, the master node transmits it to the upper PC through the serial port. The upper computer stores the collected data in the database, analyzes and processes the data, and displays the real-time change curve of temperature and humidity on the monitoring interface. Its functional features:
(1) Ultra low power consumption: a single battery works for 3 months
(2) ZigBee Networking: efficient Networking: star network, mash networking
(3) Three key setting: it can set sleep wake-up interval, ZigBee parameters, etc
2 application environment
The temperature and humidity of blood truck, plasma warehouse, fresh-keeping warehouse, storage cabinet, refrigerator, freezer, hospital, machine room, drying oven, pharmacy and other cool warehouses, freezers and normal temperature warehouses shall be monitored and recorded wirelessly.
