Working Principles of Outdoor Weather Sensors

Wind Speed and Direction Sensor

Based on the principle that the propagation speed of ultrasonic waves in the air is affected by wind speed, the sensor emits and receives ultrasonic signals. The wind speed is calculated by measuring the time difference in the propagation of ultrasonic waves in the wind direction.

Temperature Sensor

Using the diode junction voltage method, taking advantage of the characteristic that the junction voltage of the diode PN junction changes with temperature. When the temperature rises, the forward voltage drop of the diode will decrease. The temperature change is calculated by measuring the change in the junction voltage, thus realizing temperature measurement.

Relative Humidity Sensor

Based on the principle of capacitive sensors, using the characteristic that the dielectric constant of polymer materials changes after absorbing moisture. The humidity value is calculated by measuring the change in capacitance.

Air Pressure Sensor

Utilizing the piezoresistive effect of semiconductor materials, the atmospheric pressure causes the resistance value of the sensor to change, thereby determining the air pressure.

PM2.5/PM10 Sensor

Based on the principle of laser scattering, a laser irradiates suspended particulate matter in the air, generating scattered light. The sensor receives the scattered light signal and analyzes the concentration of particulate matter.

Rainfall Sensor

Mostly uses an infrared light - emitting diode and a phototransistor. When raindrops enter the detection area, they change the light propagation, causing the light intensity received by the phototransistor to change. The circuit converts this into an electrical signal, and through analysis, the size and quantity of raindrops are calculated to obtain the rainfall.

Solar Radiation Sensor

Using a thermocouple or thermopile to measure the heat of solar radiation, converting solar radiant energy into thermal energy, and then into an electrical signal output through the thermoelectric effect.
