Comprehensive Environmental Sensing Overview
- From Particulate Matter to VOCs and Climate Factors

Environmental sensors are devices designed to monitor and assess various physical, chemical, and biological parameters within the environment to provide data on its condition. These sensors are pivotal for scientific research, environmental protection, health monitoring, agricultural management, and smart home systems, offering insights into air quality, temperature, humidity, atmospheric pressure, and more.

Key types of environmental sensors include:

1. PM2.5/PM1.0/PM10 Sensors: Monitor airborne particulate matter of different sizes originating from dust, smoke, pollen, etc., which have significant health implications.
2. VOC Sensors: Detect volatile organic compounds from paints, cleaners, solvents, and indoor furnishing materials, which can pose health risks.
3. Atmospheric Pressure Sensors: Measure environmental atmospheric pressure, essential for weather forecasting, altitude measurement, and other scientific applications.
4. Temperature Sensors: Monitor environmental temperature, crucial for agriculture, meteorology, building management, and various industrial processes.
5. Humidity Sensors: Detect environmental humidity levels, impacting human comfort, structural integrity of buildings, and crop growth.

These environmental sensors provide a comprehensive toolkit for monitoring and evaluating many critical parameters of our living environment. With technological advancements, these sensors are increasingly integrated into smart devices, automating and enhancing environmental monitoring for improved quality of life and sustainability.

CurieJet® P750 Particle & Gas Sensor, with size only 29x 29x 4.9 mm, is the world’s smallest all-in-one environmental sensor. With small and slim size, also very low power consumption, developers are easy to design the whole wearable air quality monitor:
