JW-IoT provides configurable environmental monitoring solutions including sensors, communication devices, data acquisition terminals and cloud-based monitoring platforms.
How Does a Temperature Humidity Pressure Sensor Work?
A temperature humidity pressure sensor uses integrated sensing elements to measure changes in surrounding atmospheric conditions.
The temperature sensing element detects variations in ambient temperature, while the humidity sensing element measures moisture changes in the air.
The pressure sensing module measures atmospheric pressure variations caused by weather changes and altitude differences.
After measurement, the sensor converts environmental data into digital signals and transmits them through RS485 Modbus RTU communication to a data acquisition device or IoT platform.
This allows users to remotely monitor environmental conditions and analyze climate trends.
