Wind Speed Sensor
This is a waterproof design wind speed sensor that uses the standard connector of Octopus related products for easy connection with other devices. It is able to provide corresponding voltage output according to the change of wind speed. As the wind speed increases, the output voltage also increases, providing users with accurate wind speed measurement. This wind speed sensor can be applied in meteorological observation and environmental monitoring, and can be used to measure wind speed. Its waterproof design ensures reliability and durability in harsh environments.

Dust Sensor
A dust sensor is an air quality sensor used to detect the concentration of fine dust particles in the air.
It uses the principle of infrared light scattering to measure the concentration of particulate matter. The sensor contains an infrared light source and a photosensitive element inside. When airborne particles pass through the sensor, they scatter infrared light and the photosensitive element measures the intensity of the scattered light. Based on the intensity of the scattered light, the sensor can estimate the concentration of airborne particles.
The dust sensor is characterised by high sensitivity and fast response. It detects particles with diameters between 0.5 and 2.5 micrometres, which are usually the most dangerous fine dust particles in the air, such as bacteria, pollen and smoke. The voltage signal output from the sensor is proportional to the concentration of the particulate matter.
This type of sensor is usually used in air purifiers, air quality monitoring equipment and industrial environmental monitoring. It can help people understand the quality of the air around them and take appropriate measures to improve the air quality.

Temperature and Humidity Sensor
A temperature and humidity sensor is a device used to measure and monitor temperature and humidity in the environment. It provides accurate temperature and humidity data to help people understand and control environmental conditions. Such sensors have a wide range of applications in many fields, including meteorological observations, indoor environmental monitoring, agriculture, warehouse management and automated control systems.
Temperature and humidity sensors provide real-time temperature and humidity information to help users monitor and regulate environmental conditions to improve comfort, increase productivity and protect the quality of items. The wide range of applications for temperature and humidity sensors makes them an essential and important part of modern life.

UV Sensor
A UV sensor is a device used to detect and measure UV radiation in the environment. It senses the intensity of UV light and converts it into an electrical signal output. UV sensors are important in many applications including environmental monitoring, UV radiation safety, medical devices and consumer electronics. The sensor captures UV light through a light-sensitive element or photosensitive material and then converts the light signal into an electrical signal for processing and analysis. It provides accurate UV intensity measurements to help users understand the level of UV in their environment and take appropriate protective measures. Featuring high sensitivity, fast response and high stability, UV sensors are an important tool for protecting human health and safety.
