For a comparison of different alternative for spectral sensing of CO2 content in air, see the post on CO2 dual thermal sensors. For a plug-and-play ready CO2 spectral sensing unit, see the post on MH-Z16 CO2 sensor.
Introduction
Micro-hybrid is a German producer of Infra Red (IR) emitters and sensors. The company also has an online shop. In December 2021 I ordered two different “bundle” packages. These are summarised in this post.
NDIR bundle CO2
Kit of matched infrared components for analysing carbon dioxide
The kit contains:
- 5 pieces of IR emitter JSIR-350-4, marked: 20003138
- 5 pieces of dual band IR sensor MTS2, marked: 450242M30
IR emitter JSIR-350-4
The IR emitter in the CO2 bundle is centred at 4 micro meter, reaching between 2 and 8 (then weak up to 15) micro meters. The emitters are housed in TO39 casings and operated on 4.0 to 4.9 volt and 100 to 132 mA (400 to 650 mW).
Dual band IR sensor MTS2
For CO2 sensing the MT52 IR sensor is equipped with a 2xch TP E1/D2 filter, with the central wavelength at 4265 nm and a half bandwidth of 120 nm. The sensors are housed in TO39 casings.
