Abstract
An apparatus including a wireless transceiver of the gas monitoring processor that receives gas readings and a plurality of gas detectors at different locations within the predetermined geographical area that each periodically measure a current gas level at a respective location of the gas detector wherein for each gas reading of the gas detector, a processor of the gas detector compares the current gas level with a previously measured gas level, if the current gas level is different than the previous gas level, then the gas detector wirelessly transmits a message including the current gas level to the wireless transceiver of the gas monitoring processor and if the current gas level is unchanged from the previous gas level, then the gas detector transmits a beacon message to the wireless transceiver of the gas monitoring processor as an indication that the current gas level is unchanged from the previous gas level.
