A temperature humidity sensor is a measuring device that converts ambient temperature humidity into electrical signals, used for real-time monitoring regulation of environmental parameters. It is wiy applied in smart homes, industrial production, agriculture, other fields.
Definition Operating Principle The sensor collects environmental parameters via a humidity-sensitive element (e.g., capacitive humidity element) a thermal sensing element (e.g., platinum resistor), converting them into electrical signals for output. Humidity typically refers to relative humidity (%RH), i.e., the percentage of water vapor pressure in the air relative to saturation water vapor pressure. The signals are processed (e.g., amplified, calibrated) by a conditioning module transmitted as analog signals (4–20mA) or digital signals (RS485, I²C).
Application Scenarios
.Industrial: Data center monitoring, ventilation air conditioning systems. .Agricultural: Environmental control in greenhouses, with coordinated operation of light/gas sensors. .Medical: Cold chain management for pharmaceuticals, ensuring compliant storage conditions. .Smart Home: Smart hygrothermographs with Bluetooth/Wi-Fi connectivity.
