BeagleBone Black Temperature Monitor
Real-time temperature monitor powered by Beaglebone Black + TMP75, providing interactive front-end.
- Node.js (Recommend to use latest version)
- React (for front-end)
- express (for back-end)
- honoka (fetch() polyfill)
- ant design
TMP75 uses i2c protocol to send temperature data. In BeagleBone's Debian system, we can run
i2cdetect -y -r 1 to obtain the address of TMP75; and when we run
i2cget -y -f 1 0xyy (
yy is the address you get from
i2cdetect), it will returns a hex which is the temperature. We can integrate these operations into a web-server so that we can get data / send requests from browser front-end.
You should have your TMP75 connected correctly to your BeagleBone Black. For example:
- TMP75 V33 to BBB DC3.3V (P9_03)
- TMP75 GND to BBB GND (P9_01)
- TMP75 SCL to BBB SCL(P9_19, do not connect to 17 which is not occupied:) )
- TMP75 SDA to BBB SDA(P9_20, do not connect to 18 which is not occupied:) )
- TMP75 I/O to BBB GPIO(whichever has not been occupied is OK)
Then clone this repository to your BeagleBone Black and install dependencies:
$ git clone https://github.com/kirainmoe/beaglebone-temperature-monitor $ cd beaglebone-tempature-monitor $ npm install
Modify your config file. Note that app can detect your i2c address automatically, but you should specify the GPIO port):
$ npm start # or: $ node index.js
Open your browser (default port is 2333):
