超低功耗二氧化碳传感器LP8

发布时间 : 2019-08-11 11:01


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.


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
