This module contains a sensor to detect the concentrations of various harmful gases in the air. The MQ-135 can record gas concentrations from 300 to 5000ppm. This module ordered both an analog output and a digital output, which triggers an adjustable concentration. Properties: Sensitive to: Ammonia, sulfur, gasoline, smoke Warm up voltage: 5 ± 0.2V Warm up current: 150mA Warm-up capacity: 300mW Detection zone: 300 to 5000ppmm Sensitivity: ≥3% Response Time: ≤1s Recovery Time: ≤30s Max humidity: 95% https://elecena.pl/product/27738389/opencircuit-mq-135-air-quality-sensor 2025-01-22 https://elecena.pl/product/27738389/opencircuit-mq-135-air-quality-sensor 2025-04-20 https://elecena.pl/product/27738389/opencircuit-mq-135-air-quality-sensor 2026-02-23 https://elecena.pl/product/27738389/opencircuit-mq-135-air-quality-sensor 2026-02-25 https://elecena.pl/product/27738389/opencircuit-mq-135-air-quality-sensor 2026-03-02 https://elecena.pl/product/27738389/opencircuit-mq-135-air-quality-sensor 2026-03-04 https://elecena.pl/product/27738389/opencircuit-mq-135-air-quality-sensor 2026-04-08
