Innovative Modularized Hardware Design Provides Flexibility of Selecting Sensor Modules for Different Applications
The sensor modules inside Sniffer4D use state-of-the-art gas sensors. Each sensor module is equipped with a dedicated 16MHz microcomputer to run our proprietary filtering, bias correction, humidity and temperature correction algorithm. Users can customize the configuration at their choice.
Sniffer4D is able to obtain air pollution data at street levels and at various heights
Ensure Sniffer4D's excellent data linearity, repeatability, reliability and short response time
Verified Data Quality
Real-time Data Transmission
Ground vehicle mounted Sniffer4D supports one-to-one, one-to-many, many-to-one and many-to-many data transmissions between multiple Sniffer4Ds and multiple PCs. 4G module and telemetry radio can work simultaneously.
Sniffer4D is able to transmit real-time gas data to multiple PCs at the mission site,
control center and other places through 4G/telemetry radio.
Data retrieval algorithm and SD Card auto backup provide double security
Data retrieval algorithm - when the connection between a Sniffer4D and a computer temporarily breaks down, all the collected data will be automatically transmitted to the receiving computer after the connection is restored. Sniffer4D also backs up mission data to the onboard SD card at the same time.
Users can choose up to 9 sensing modules from below
