Sample Smart Faucet using AT&T's M2X and Raspberry Pi
This Python app for your Raspberry Pi records how much water and what temperature water is being used at a faucet connected to your Pi using a flowmeter and a temperature sensor. It then will send that information to AT&T's M2X service where it is stored for future retrieval and analysis.
If you want to display the data from your faucet, here’s a quick app that you can deploy to Heroku: https://github.com/attm2x/m2x-sample-cleverfaucet-web
What you need
- Familiarity with the AT&T M2X API
- Raspberry Pi running RaspBian
- A free AT&T M2X Account.
- Suggested Sensors:
- DS18B20 Digital temperature sensor - If using a different one, make sure it is waterproof
- Liquid Flow Meter - Plastic 1/2" NPS Threaded
- 4.7k Ohm resistor, jumper wires, and a breadboard
Dependencies
- Python running on your Raspberry Pi (Tutorial)
- m2x-python - v3.0.4
- RPi.GPIO - If you are running Raspbian this should already be included with its Python installation
Instructions
- Clone this repository
$ git clone https://github.com/attm2x/m2x-sample-cleverfaucet
$ cd faucet- Create a new M2X device.
- Copy the Device ID from the device page.
- From your M2X account page get your Master API Key.
- Create two data streams in that device. One named 'water_use' and the other named 'temperature'.
- In main.py replace MASTER_API_KEY and DEVICE_ID:
client = M2XClient(MASTER_API_KEY)
device = client.devices.get(DEVICE_ID)with:
client = M2XClient('your_key_here')
device = client.devices.get('device_id_here')-
WARNING: Wiring this incorrectly could fry your Pi so proceed with caution.
Use the following diagram to connect the sensors to your pi:
Here is the GPIO Diagram from the various Pi Models:
-
Place the faucet directory on your Pi. Now simply run the following:
$ sudo ./start.sh- Check out the data streams on M2X and you should see them update when you use the faucet!
