Product Specification


The LP8 miniature 10,000 ppm CO2 sensor is designed from the ground up for long-term battery or solar-powered applications. It utilizes a flexible CO2 measurement period to minimize power consumption. One measurement requires only 11.9 mJ of energy.


Key benefits

3.6mC per measurement (11.9mJ @ 3.3V)

Miniature size (Senseair® S8 format)

A wide supply voltage range enables a variety of battery options

Adjustable measurement period by host

Adjustable ABC period by host



Ultra-small footprint NDIR sensor

Designed for long-term battery operation

Variable measurement period to save energy

A wide range of voltages (2.9-5.5V) enables a variety of power options. For example it can be powered by 3 alkaline 1.5V batteries, or a single 3.6V Li-SOCl2 battery for a more compact alternative.
