A temperature and humidity transmitter measures ambient conditions using integrated sensors. The temperature sensor (typically RTD or thermistor) detects temperature changes, while the humidity sensor (capacitive or resistive) measures moisture content in the air. These signals are converted into electrical outputs by the transmitter’s electronics, processed, and transmitted as a standardized analog (4–20 mA) or digital signal. The data is used for monitoring, control, and maintaining stable environmental conditions in HVAC, agriculture, and industrial applications.
