BBQ Fan Controller design with ESPHome firmware
The Meat Fan is currently on hold, first I'll focus on creating just a BBQ Thermometer, see below.
BBQ Thermometer design with ESPHome firmware
- ESP32 Development board
- PCB board (5 x 7cm or bigger)
- 15 pin female header (2 times). Optional, but allows for easy replacing and detaching the ESP.
- Thermocouple (k-type) hardware
- MAX31855 thermocouple board
- Thermocouple (k-type)
- Meat probe (thermistor) hardware
- Meat probe (100k Ohm at 25°C)
- Resistor (100k Ohm)
- 0.1uF capacitor (for reducing noise on the ADC pin)
- You can use any of the ADC1 pins for the Meat probes.
- You can use any GPIO pin for the 3 pins connecting to the MAX31855. Pin mapping:
DO
=>spi.miso_pin
CS
=>sensor[platform=max31855].cs_pin
CLK
=>spi.clk_pin
