Product Description

Overview

This sensor module has an MG-811 onboard as the sensor component. There is an onboard signal conditioning circuit for amplifying output signal and an onboard heating circuit for heating the sensor. The MG-811 is highly sensitive to CO2 and less sensitive to alcohol and CO. It could be used in air quality control, ferment process, in-door air monitoring application. The output voltage of the module falls as the concentration of the CO2 increases.

Features

  • Analog and digital output
  • Onboard signal conditioning circuit
  • Onboard heating circuit
  • Sensor jack eliminates soldering the sensor and allows plug-and-play
  • 4-pin interlock connectors onboard
  • 4-pin interlock cables included in the package
  • Compact size

In the Package

  • A fully tested MG-811 CO2 sensor module
  • A 4-pin 30cm cable (with interlock connector on one end, free on the other)

    Nice package and the best price I could find for a complete sensor with breadboard. Works well; using for a science fair project to measure CO2 in air of a greenhouse, and have interfaced it with an arduino using the instructions here: http://www.veetech.org.uk/Prototype_CO2_Monitor.htm
    Very happy with this purchase and with Sandbox Electronics. Great customer service.

    Exellent. The circuitry on the board is what separates this co2 sensor from other breakouts. Run it constantly for 48 hrs to break it in. Do not calibrate until break in is complete. The instructions in the link on the first review were spot on. Remember to supply POWER to the breakout and the arduino (not USB power!) You can buy external multi channel ADC for cheap. Get a 16 bit ADC TO GET FULL PRECISION
