6.13.20. Humidity/Temperature Sensor Circuits
The temperature/humidity sensor board has the temperature and humidity sensors.
The TEMP is an analog signal, which informs the information concerning the printer environment temperature to IC300 (SOC).
IC300 receives this analog signal, converts it to a digital signal internally and detects the printer environment temperature.
The HUMI is an analog signal, which informs the information concerning the printer environment humidity.
IC300 controls the printing process in accordance with the detected printer environment temperature and humidity.
