RT based_ Distributed wireless temperature monitoring system based on thread

One 、 Project brief introduction

be based on RT_thread Distributed wireless temperature monitoring system It is a smart home that can realize remote monitoring DIY project , It can be applied to families 、 The office 、 Multi node temperature monitoring from small fields such as classrooms , It supports temperature data of six nodes at most . Six points are responsible for temperature data collection , A receiving node acts as a gateway , adopt WIFI Upload to the cloud , The mobile computer realizes remote monitoring , Practical and interesting ;

Two 、 Sensor part

sensor	Number
DS18B20	2
NRF2401	3
ESP8266	1

Sending node
1. take DS18B20 Temperature sensor docking sensor Components , Read correctly ds18b20 Temperature sensor data ;
2. Use nRF24L01 software package , The temperature data is transmitted wirelessly to the receiving node , from nRF24L01 The feature determines that the sending node can support up to six points .

Receiving node
1. Use nRF24L01 software package , Receive data from the sending node ;
2. Send the data to the upper computer through the serial port .

Upper computer
1. Through serial port communication, the received node data is transmitted to the upper computer for display .

OneNet cloud
1. adopt ESP8266-wifi The module transmits the data of the receiving node to OneNet cloud ;
2. Connect OneNet cloud , Make applications according to personal preferences to realize remote monitoring .

preparation
1.RT-Thread Source code （ It is recommended to use 3.1.x edition ）
2.ENV Tools
3. Upper computer ： Serial assistant
