Wiring of all pins of the sensor #16

Hey ostaquet,

firstly thanks for the information you give about the sensor and the cool library. I have a question in regards of the wiring. Online it's often recommended to wire all pins, while the datasheet implies not to do that, if I understood it correctly.

Fir instance here: https://playground.arduino.cc/Main/MQGasSensors/

Also the traces on this PCB from a manufacturer implies it's okay to wire everything: https://eckstein-shop.de/Pololu-Carrier-for-MQ-Gas-Sensors-Bare-PCB-Only

On the first glance, it looks like both ways are okay. What's your opinion on the issue?

Kind regards

In my experience, both are OK. You could wire everything or wire only what is required. It will not impact the results.
