SEN-MQ8 Developer boards - gas sensor, hydrogen, MQ-8

This analogue gas sensor has a small heating element with an electronic-chemical sensor. It is suitable for indoor use and can only output accurate readings after the warm-up phase is complete.

Features - compatible with Arduino - compatible with Raspberry Pi only in combination with part no. RPI ADC (see accessories) - 100 - 1000 ppm measuring range - high sensitivity (adjustable via potentiometer) - fast response time - evaluation of measured values from microcontroller (analog) - threshold setting possible (digital) - 24 V loop voltage - 5 V heating voltage - 29 Ohm heating resistor at room temperature - - -10 - +50 °C Betriebstemperatur

measurable substances - hydrogen (H2) - various gases containing hydrogen

Connections - VCC: power supply 5V - GND: Ground connection - AOUT: Analog Output - DOUT: Digital Output

Dimensions - L x W x H: 52 x 20 x 18 mm

Note900> Attention: The sensor gets warm during operation!
