Figaro TGS 2603 pin connection

Other Hardware Sensors
1

Heloo Arduino Crew, nice to meet you,

I bought TGS 2603 sensor - here is product documentation

So I connected it this way
PIN 1: heater -> GND (near analog pins)
PIN 2: sensor electrode -> A0
PIN 3: sensor electrode -> A1
PIN 4: heater -> 5V

What I'm doing wrong?

Im new in arduino world, i bought starter kit and this sensor cuz i wanted to create something useful.

Thanks!

Hi Yato94,

What I'm doing wrong?

Not reading the datasheet .........

Just connect the TGS 2603 according to the schematic in the datasheet and it will work. Don't forget to condition the sensor for 96 hours.

Oh, so it work the same way as MQ-sensors, just there is no need to put 2 pins together? Tarbo, thank you :slight_smile:

which board you are using ? i am using esp 32 board , and i connection AN2 to analog pin and 5v to vcc and gnd to gnd , but the value cant been reading
