This allows to track and show them in common MQTT apps. 23 | The MQTT messages contain JSON with timestamp and value: 24 | 25 | { "status": "ok", "timestamp": "2020-11-13T17:08:57.753064", "value": 9.697, "unit": "°C", "formatted": "9.7" } 26 | 27 | ### CSV Logging 28 | The temperature readings are written to CSV files and held for 32 days. This also allows to immediately re-fill the graphs view after restart. 29 | 30 | ## Hardware 31 | 32 | - Raspberry PI 3B 33 | - Official Raspberry PI 7" touch display, 800x480 (expensive, but well supported in Raspbian, multi-touch) 34 | - Official Raspberry power supply 5.1V/2.5A with additional 330uF capacitor for stabilization (Raspi is quite picky here...) 35 | - Heat sink on Raspberry CPU (... to avoid the random crashes that may occur otherwise) 36 | - DS 18B20 temperature sensors (1-Wire bus allows many sensors at the same GPIO port, well supported in Raspbian) 37 | - TSIC 306 temperature sensors (high accurracy, expensive, but already installed from a previous project) 38 | 39 | ## Platform 40 | 41 | - Raspbian Buster 42 | - Python 3.7 43 | - UI toolkit Kivy (nice and simple UIs with multi-touch support) 44 | - Charts with Kivy Garden Graph (fast drawing) 45 | - TSIC temperature sensors: python module tsic (sensor reading based on pigpio) 46 | - GPIO access: pigpio (IO with precise timing) 47 | 48 | ## Installation / Configuration 49 | 50 | Steps last performed on latest Raspbian of 2021-01-23 51 | ``` 52 | # Install Raspbian buster to SD card, 53 | # optionally
