sensor mq4 ficha tecnica

MQ4 gas sensor has high sensitivity to methane, also has antiinterference to alcohol and other gases. It is widely used in domestic gas leakage alarm, industrial flammable gas alarm and portable gas detector. Tips:For more parameter information, please refer to the latest manual provided by salesman. 26Ω±3Ω (room tem.)

Reflective Optical Sensor with Transistor Output TCRT5000, TCRT5000L Vishay Semiconductors DESCRIPTION The TCRT5000 and TCRT5000L are reflective sensors which include an infrared emitter and phototransistor in a leaded package which blocks visible light. The package includes two mounting clips. TCRT5000L is the long lead version. FEATURES

The sensors performance will be changed badly if sensors be sprayed polluted by alkali metals salt especially brine, or be exposed to halogen such as fluorin. Touch water Sensitivity of the sensors will be reduced when spattered or dipped in water. Freezing Do avoid icing on sensor’surface, otherwise sensor would lose sensitivity.
