This analogueue gas sensor has a small heating element with an electronic-chemical sensor. It is suitable for indoor use. It can only output accurate measured values after the warm-up phase has been completed. It is compatible with all microcontrollers (an A/D converter is required for Raspberry). The sensor is characterized by its fast response time and its wide detection range. The sensitivity can be adjusted by a potentiometer located on the bottom of the module. https://elecena.pl/product/28015626/joy-it-gas-sensor 2025-03-12 https://elecena.pl/product/28015626/joy-it-gas-sensor 2025-05-22 https://elecena.pl/product/28015626/joy-it-gas-sensor 2025-07-18 https://elecena.pl/product/28015626/joy-it-gas-sensor 2025-09-17
