Carbon dioxide sensor (with analog output, TTL level signals, temperature output adjustment).

Dimensions: 32mm X 22mm X 30mm (L * W * H).

Main chip: LM393, carbon dioxide gas sensor.

Operating voltage: DC 6V.

Features:

• It has a signal output indication.
• Dual signal output (analog and TTL level).
• The valid TTL signal is low (can be connected directly to a microcontroller).
• Analog output selection (0 ~ 2V/0-4V), default 0-2V.
• High sensitivity and good selectivity for carbon dioxide.
• Long lifespan and reliable stability.
• Quick response and recovery characteristics.
• Design that allows easy testing of the sensor.

Applications: CO detection devices for home use and environment. Suitable for detecting carbon dioxide concentration. The detection range of the carbon dioxide sensor is 0-10000ppm.
