docs are inconsistent

I purchased several MQ sensors, originally sourced from DFrobot. The pin connections shown on this RobotShop page (1=output, 2=gnd, 3=Vcc) are wrong, It should read (1=output, 2=Vcc, 3=Gnd). The DFRobot site is also mixed up, , This page https://www.dfrobot.com/wiki/index.php/Analog_Gas_Sensor(MQ2)_(SKU:SEN0127) writes it wrong twice, but the picture is right. This page https://www.dfrobot.com/wiki/index.php/Analog_Gas_Sensor_SKU:SEN0127 removed the incorrect text, and the picture is right. I think pin 2 should be Vcc because their 'Gravity' connector convention has it this way, AND the wire colour on the provided leads is red. Not much to go on.

les documents sont incohérents

J'ai acheté plusieurs capteurs MQ, originaires de DFrobot. Les connexions des broches montrées sur cette page RobotShop (1 = sortie, 2 = gnd, 3 = Vcc) sont incorrectes, il convient de lire (1 = sortie, 2 = Vcc, 3 = Gnd). Le site DFRobot est également mélangé, Cette page https://www.dfrobot.com/wiki/index.php/Analog_Gas_Sensor(MQ2)_(SKU:SEN0127) écrit deux fois de manière fausse, mais la photo est correcte. Cette page https://www.dfrobot.com/wiki/index.php/Analog_Gas_Sensor_SKU:SEN0127 a supprimé le texte incorrect et l'image est correcte. Je pense que la broche 2 devrait être Vcc parce que leur convention de connecteur «Gravity» l’a de cette façon, ET que la couleur du fil sur les fils fournis est rouge. Pas suffisant pour continuer.
