Description
Features
- Use ESP32 as a micro controller.
- MAX6675 k-type thermocouple for temperature sensor.
- ESP32 output PWM to SSR for heater control.
- ESP32 use PID control.
- WiFi Button: Short pressed for switch WiFi on/off. Long pressed for reset WiFi AP.
- If WiFi is on, ESP32 can publish temperature and PWM Duty Ratio by MQTT.
