The MQ series of gas sensors, in particular the MQ5 sensor, is an important resource for monitoring air quality in working environments exposed to potential risks from natural gases and LPG (Liquefied Petroleum Gas). These sensors provide an efficient solution to ensure that concentrations of these gases remain within safe limits. https://elecena.pl/product/25977844/333119-developer-boards-gas-sensor-liquid-gas-mq-5 2024-05-26 https://elecena.pl/product/25977844/333119-developer-boards-gas-sensor-liquid-gas-mq-5 2025-04-07
