LP8 pin headers
Miniature CO2 sensor module for battery-powered applications. A wide supply voltage range enables a variety of battery options.
- Miniature size
- Adjustable ABC period
- Low power consumption
- Variety of battery options
Senseair LP8 is a miniature sensor module which targets battery-powered applications. It gives customer a full control on sensor integration into a host system, flexibility in changing of the CO2 measurement period and consequently power consumption. One measurement requires only 3.6mC of charge (or energy 11.9mJ at 3.3V battery supply). The sensor is supposed to be switched off between measurements to minimise power consumption. A wide 2.9 to 5.5V supply voltage range enables long duty if sensor is powered from three alkaline 1.5V batteries. A compact alternative is to power sensor from a single 3.6V Li-SOCl2 battery. The LP8 provides a communication protocol which allows customer changing measurement period on the fly and control ABC (Automatic Baseline Correction) period. Background- and zero calibrations are implemented.
