# poolmonitor, a collection of data logging utilities Currently just logging a temperature probe on both my hot tub and my pool. How does it work? Raspberry Pi 3 + Temperature Probe => Python3 Script => Send Data to IoTPlotter.com to log it ## Install ### Step 1 - Clone the repository ``` cd ~; git clone https://github.com/grumpymaker/poolmonitor.git ``` ### Step 2 - IoTPlotter.com * Create an account * Create an API Key * Create a feed and name a sensor. ### Step 3 - Edit Settings Add the following to your profile (e.g. ~/.profile, ~/.bashrc, etc): ``` export SENSORPATH="/sys/bus/w1/devices/28-SOME_DEVICE_ID_HERE/w1_slave" export IOTPLOTTERAPI="API_KEY_HERE" export IOTPLOTTERFEED="http://iotplotter.com/api/v2/feed/FEED_ID_HERE" export IOTPLOTTERSENSOR="POOL_TEMP" export MAKEWEBHOOK="MAKE_WEBHOOK_HERE" ``` Source the profile and/or logout and log back into SSH. ### Step 4 - Test run the script See if the data shows up in the IoTPlotter Feed. ``` python3 ~/poolmonitor/iotplotter.py ``` ### Step 5 - Set a cronjob to run it periodically ``` crontab -e */5 * * * * . /home/pi/.profile; python3 /home/pi/poolmonitor/iotsender.py ``` ## Hardware Sourced from anywhere: * Raspberry Pi 3 B+, 4, etc (install raspbian, enable ssh, update and secure, install python3 / python3-pip, pip install requests, etc) * Case for the RPi (nice to have) * Power supply for RPi Adafruit Parts: * 1 x Large Plastic Project Enclosure - Weatherproof with Clear Top[ID:905] = $19.95 * https://www.adafruit.com/product/905 * 1 x Waterproof DS18B20 Digital temperature sensor + extras[ID:642] = $14.95 * https://www.adafruit.com/product/642 * 1 x Half-size breadboard[ID:64] = $5.00 * https://www.adafruit.com/product/64 * 1 x Adafruit Pi T-Cobbler Plus Kit Breakout for 2x20 Raspberry Pi [ID:1989] = $7.50 * https://www.adafruit.com/product/1989 Hardware setup guide: https://learn.adafruit.com/adafruits-raspberry-pi-lesson-11-ds18b20-temperature-sensing/hardware > If you are using the "high temperature" version of the DS18B20 we sell, connect Orange Stripe to 3.3V, White connects to ground and Blue Stripe is data, pin #4. > You still need a ~4.7K-10K resistor from data to 3.3V
