Description：
The air quality sensor can monitor parameters such as PM2.5/10, TVOC, eCO2, temperature and humidity in the air, and can be used indoors and outdoors.
Style：
The air quality sensor has three appearances to choose from, and you can choose the appropriate air quality sensor according to your needs.
Detail：
style 1：
（1）Standard guide rail structure design, exquisite appearance, screws installed on both sides, can be wall-mounted or ceiling-mounted. Two types of TVOC and TVOC+eCO can be detected.
（2）Built-in high-quality probes, using high-density material shell, wear-resistant and anti-drop, built-in high-quality probes, high accuracy, low power consumption, and wide range.
style 2：
(1）Surrounding heat dissipation design, good ventilation, fast heat dissipation and high sensitivity. It can detect TVOC+eCO, +PM2.5/10+temperature and humidity six in one.
(2) Single-hole fixing, easy to install, can be wall-mounted on the vertical ground.
(3) Built-in laser probe, high sensitivity.
style 3：
(1) Wall-mounted installation, installation of screws on both sides saves time and effort, and can also be installed on the ceiling.
(2) The built-in waterproof probe selects the photochemical gas detection probe for waterproof treatment, and the probe shell is designed with multiple pores to ensure air circulation and accurate data.
(3) Closed waterproof strip The built-in closed waterproof strip has a significant moisture-proof effect.
