The enveloped MQ-135 have 6 pins ,4 of them are used to fetch signals, and other 2 are used for providing heating current. Electric parameter measurement circuit is shown as Fig.2 E. Sensitivity • BCR135S: For orientation in reel see package information below. • Pb-free (RoHS compliant) package • Qualified according BCR135 Electrical Characteristics at TA = 25°C, unless otherwise specified. The 6N135 and 6N136 are optocouplers with a GaAIAs infrared emitting diode, optically coupled with an integrated photo detector which consists of a photo diode and a high-speed transistor in a MQ-135_Hanwei.pdf. Structure and configuration of MQ-135 gas sensor is shown as Fig. 1 (Configuration A or B), sensor composed by micro AL2O3 ceramic tube, Tin Dioxide (SnO2) sensitive The LM135, LM235, LM335 are precision temperature sensors which can be easily calibrated. They operate as a 2-terminal Zener and the breakdown voltage is directly proportional to the absolute
