PORTABLE GAS ANALYZER WITH WIRELESS MEASURING MODULE Russian patent published in 2022 - IPC G01N27/26 

FIELD: wastewater treatment.

SUBSTANCE: invention relates to devices for determining the concentration of methane (CH₄), carbon monoxide (CO), hydrogen sulfide (H₂S), the volume fraction of oxygen (O₂) in water and sewer wells, as well as in buried water and sewer pumping stations and is intended for the detection and monitoring of hazardous gases in the ambient air of such wells and stations. A portable gas analyzer with a wireless measuring module (WMM gas analyzer) includes measuring and display modules connected by wireless communication, measuring and display modules are made in separate housings, while the housings are made of polymer and are waterproof, the measuring module is made of two compartments, the first compartment contains electrochemical and infrared gas sensors, the second compartment contains converter printed circuit boards connected to gas sensors, display module, connected to the measuring module by wireless communication via the nRF24101 protocol for data exchange, coils of wireless chargers are located on the housings of the measuring and display modules, each of the measuring and display modules is equipped with a display, sound and light indications.

EFFECT: invention provides reliable wireless communication at a distance of 100 meters of line of sight and 30 meters indoors, increased battery life, as well as reduces power consumption and facilitates taking the readings.
