CCS801 Ultra-low power multi-gas sensor for indoor air quality
Cambridge CMOS Sensors (CCS) micro-hotplate technology provides a
unique silicon platform for the CCS80x range of Metal Oxide (MOX) gas
sensors. These devices enable sensor miniaturisation, have ultra-low
power consumption and provide fast response times due to the ability to
heat the micro-hotplate very quickly.
The micro-hotplates are fabricated using a robust silicon dioxide
membrane and include an embedded tungsten heating element to heat
the MOX based sensing material. The MOX sensing material can be
heated up to 500°C to allow the electrical resistance of the MOX sensor
to be monitored to detect the target gas. By exploiting the fast heater
cycling times, temperature modulation techniques can be used to
reduce the device power consumption and implement advanced gas
sensing methods.
Software libraries containing proprietary algorithms and example
Android applications are available for indoor air quality monitoring and
alcohol breathalyser use cases.
Product Overview
CCS801 is an ultra-low power MOX multi-gas sensor for monitoring
indoor air quality including Carbon Monoxide (CO) and a wide range of
Volatile Organic Compounds (VOCs) such as Ethanol. CCS801 can be
used as an equivalent carbon dioxide (eCO2) sensor to represent eCO2
levels in real world environments, where the main source of VOCs is
from humans.
For CCS801 a supply voltage (VH) is provided to the integrated micro-
heater and the gas concentration can be correlated to the change in
resistance of the MOX sensing layer (RS).
VH can be set using a low-dropout (LDO) regulator or operated in
constant or pulsed PWM mode to reduce power consumption. The
sensor resistance (RS) is typically determined using a series load resistor
(RL), a reference voltage (VREF), and by reading an output voltage (VOUT)
with an Analogue-to-Digital Converter (ADC). The reference voltage
(VREF) must only be enabled during the sensor reading.
CCS801 is supported in a compact 2 mm x 3 mm DFN (Dual Flat No lead)
package as standard.
