thingiverse

# Pizza Oven Temperature Sensor It is programmed using [ESPHOME](https://esphome.io/) . It displays the current temp, max and min temps (over the last 10mins) on the OLED Screen. It also sends the sensor reading to [Home Assistant](https://www.home-assistant.io/), so you can get notifications from your smart home when the oven has reached temperature / cooled down enough to be put away. ## ESPHOME Code The ESPHome configuration code for this project can be found here https://pastebin.com/iGz8zryn or pizza_oven_sensor.yaml in files section you will need to download the ttf font for the OLED display and place them in your esphome config dir (e.g //homeassistant/config/esphome) - slkscr.ttf - https://www.dafont.com/silkscreen.font - BebasNeue-Regular.ttf - https://www.dafont.com/bebas-neue.font - arial.ttf - https://www.dafont.com/bebas-neue.font?text=arial.ttf ## Parts - [MakerHawk ESP32 Development Board WiFi with 0.96inch OLED Display](https://www.amazon.co.uk/MakerHawk-Development-0-96inch-Display-Compatible/dp/B076P8GRWV) - [SNOWINSPRING 1 Set Max6675 Module + K Type Thermocouple Sensor Module for & 1Pcs K Type 50X5Mm 800C Probe Thermocouple Temperature Sensor Cable 9.8Ft 3 Meters](https://www.amazon.co.uk/SNOWINSPRING-Max6675-Module-Thermocouple-Temperature/dp/B08HQ81MVH/ref=sr_1_1?dchild=1&keywords=SNOWINSPRING+1+Set+Max6675+Module+%2B+K+Type+Thermocouple+Sensor+Module&qid=1620483094&s=computers&sr=1-1-catcorr) ## Resources - https://resource.heltec.cn/download/WiFi_Kit_32/WIFI_Kit_32_pinoutDiagram_V2.pdf - https://esphome.io/components/sensor/max6675.html?highlight=max6675 ## Wiring of the esp32 to the max6675 - esp32 pin GND to max6675 gnd - esp32 pin 3.3v to max6675 vcc (104nf cap between vcc & gnd) - esp32 pin 2 (cs) to max6675 (CS) - esp32 pin 18 (SCK) to max6675 (SCK) - esp32 pin 19 (miso) to max6675 (SO)
