SEN-MQ7 Developer boards - Gas sensor, carbon monoxide, MQ-7

This analog gas sensor has a small heating element with an electronic-chemical sensor. It is suitable for use in buildings and can only provide accurate readings once the warm-up phase is complete.

Features - compatible with Arduino - compatible with Raspberry Pi only in combination with art. no. RPI ADC (see accessories) - 300 - 10000 ppm Measuring range - high sensitivity (adjustable via potentiometer) - fast reaction time - Evaluation of the measured values from the microcontroller (analog) - Threshold value setting possible (digital) - &rt; 10 V loop voltage - 5 V Heating voltage - 31 Ohm heating resistor at room temperature - - 20 - +50 °C Operating temperature

measurable substances - Carbon monoxide (CO)

Connections - VCC: Power supply 5V - GND: Ground connection - AOUT: Analog output - DOUT: Digital output

Dimensions - L x W x H: 52 x 20 x 13 mm

Note Attention: The sensor gets warm during operation!
