Overview
The Inventory Master’s multi-function smart air quality sensor with wireless options is a multi-parameter air quality sensor, which can detect and output pm2.5, pm10, pm1.0, TVOC, temperature, humidity, ozone, alcohol, methane, ammonia, hydrogen sulfide, sulfur dioxide and other air quality in real time Quality indicators, all gas detection uses independent sensor probes. The type of detection gas can be freely selected and matched. It has compact design, small footprint, complete functions, stable performance, and high-cost performance. It supports serial port RS485, 4G, Bluetooth, WIFI and other output methods, which greatly facilitates air quality detection and the Internet of Things. Development and application of gas detection solutions.
Features
- Convection hole design
- Multi-parameter integration
- 3 light displays
- 24 h continuous online detection
- Multiple gasses detected and freely combined
