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.
Temperature and humidity sensor includes a capacitive humidity sensor and a digital temperature sensor, built-in one high-performance 8-bit SCM, standard one-wire interface, outdoor wall and pole mounted, all automated calibration, completely interchangeability, with excellent quality, fast response, waterproof function, high cost performance, low power consumption, long signal transmission distance above 20m.
