Tips: What is a temperature and humidity sensor?
Temperature and humidity sensor is a kind of sensor that detects the temperature and humidity of the external environment. It converts the measured ambient temperature and humidity into electrical (frequency) signals for easy processing, display and recording. It is an important chemical sensor, and is widely used in warehousing, industrial production, process control, environmental monitoring, household appliances and meteorology. The temperature and humidity sensor is composed of three parts: temperature and humidity sensing elements, transformation elements and measuring circuits. For humidity sensing elements, the common structural forms include capacitive type and resistive type, which transmits the measured humidity by detecting the change of capacitance and resistance respectively.
