10Pcs Mq 135 Ammonia Sulfide Benzene Vapor Gas Sensor Module Shield Liquefied Electronic Detector For Arduino

Features : - Sensitive material MQ135 gas sensor is used in clean air low conductivity tin oxide (SnO2). When the sensor is kept in their environment In the polluting gases the conductivity sensor with increasing air pollution in gas concentration increases. - Using a simple circuit can change the conductivity Conversion of an output signal corresponding to the gas concentration. - MQ135 sensor for ammonia, sulfide benzene vapor high sensitivity of the smoke and other harmful monitor is also very good. This sensor can be seized measure a variety of harmful gases is a low-cost sensors for a variety of applications. Speciffications : 1. It adopts high quality double panel design with power indication and TTL signal output indication 2. It has DO switch signal (TTL) output and AO analog signal output 3. The TTL output valid signal is low. (When the output is low, the signal light is on, it can be directly connected to the MCU or relay module) 4. The voltage of the analog output, the highe Lees meer over de 10Pcs Mq 135 Ammonia Sulfide Benzene Vapor Gas Sensor Module Shield Liquefied Electronic Detector For Arduino van huismerk in de productgroep elektronica
