Air Quality Sensor High Sensitivity Particle Concentration Laser Sensor for Carbon Dioxide Temperature Humidity

Feature: 1. Integrated Sensing Module: This sensor is an all in one air quality module with integrated laser dust sensor, infrared CO2 sensor, electrochemical formaldehyde sensor, VOC sensor, temperature and humidity sensor. 2. Accurate Measurement: This sensor can accurately measure the concentration of various gases, with UART (TTL level) communication interface, which makes the use more accurate. 3. Simultaneous Output: This sensor can achieve simultaneous output of carbon dioxide, formaldehyde, TVOC, PM2.5, PM10, temperature, humidity, a total of seven groups of data, powerful function. 4. Stable Data: High sensitivity and stable data. Temperature is accurate to 0.01 celsius , humidity is accurate to 0.04percent , and seven sets of sensor monitoring data are automatically output through UART signal every 2 seconds. 5. Widely Use: This sensor can be used in gas detectors, air conditioners, air quality monitoring, air purifiers, HVAC systems, smart homes or other IAQ systems.
