while both PAR and LUX are measures of light, PAR focuses on the specific light range (400-700 nm) that is used for photosynthesis by plants, whereas LUX measures the overall brightness of light as it affects human vision across the entire visible spectrum.

Pyranometers the most widely used sensors for measuring solar irradiance. Pyranometers are designed to measure the solar radiation energy reaching a surface. Pyrheliometer: Pyrheliometers are used to measures the direct normal irradiance, or the amount of solar radiation received from the sun when it is at its highest point in the sky.

sonic snow depth sensor is a type of sensor that uses sound waves to measure the depth of snow accumulation. This sensor works by emitting high-frequency sound pulses towards the ground and measuring the time it takes for the sound waves to reflect back to the sensor after bouncing off the snow surface. By analyzing the time it takes for the sound waves to return, the sensor can accurately calcula···

The instrument used to measure visibility is called a visibility meter or a visibility sensor. This device is designed to quantify the distance over which a light source can be seen in the atmosphere, which is a measure of atmospheric clarity or transparency. Visibility is affected by various factors, including the concentration of particles such as dust, smoke, water droplets, and ice crystals in···

visibility meter, also known as a visibility sensor or visibility instrument, is a device used to measure the distance at which objects or targets can be clearly discerned in the atmosphere. It provides a quantitative assessment of visibility, indicating how far an observer can see under prevailing atmospheric conditions. Visibility meters are essential tools in meteorology, aviation, transportati···

The function of a visibility sensor is to measure and report the visibility or clarity of the atmosphere. It provides information about how far an object or target can be seen and identified in a given environment. The sensor detects and quantifies the presence of atmospheric conditions that can reduce visibility, such as fog, mist, haze, smoke, or precipitation.

CO2 sensor is a device that can detect and measure the concentration of carbon dioxide (CO2) in the environment. It usually consists of a sensitive element, a signal processing circuit and an output interface.CO2 sensor has a wide range of applications in the fields of environmental protection, indoor air quality monitoring, and industrial production process control. It can help monitor air qualit···

Rain and snow sensor transmitter is a device that can detect rain drops, snowflakes and other precipitation patterns and convert them into electrical signals, which is usually used in automatic weather stations, intelligent transportation systems, weather forecasting, security monitoring and other fields. Rain and snow sensor working principle:The working principle of the rain and snow sensor tran···

noise sensor is a device used to monitor and measure environmental noise levels, which are commonly used in areas such as industry, construction and urban environments. How noise sensors work: Noise sensors usually contain components such as a microphone (sound sensor), signal amplifier, A/D converter (analog/digital converter), data processing unit, and power supply.

Atmospheric visibility meter is a kind of instrument used to measure the visibility in the atmosphere, which can monitor and record the change of atmospheric visibility in real time, and is usually widely used in the fields of transportation, meteorology, environmental protection and so on. Its working principle is mainly based on optical sensing technology.
