CCS801
Key Benefits：
Ultra-low power consumption - ideal for battery operated devices
High sensitivity
Fast heating time <15ms for quick response
Compact 2mm x 3mm DFN package for small form factor designs
Applications：
Total VOC sensor for Indoor air quality monitoring
Toxic gas (CO) detection
Detection of Ethanol
Alcohol breathalyser in consumer devices
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 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).
Miniaturisation
CCS801 is supported in a compact 2 mm x 3 mm DFN (Dual Flat No lead) package as standard. Other package options may be available upon request. The inherent design of this sensor enables ultra-low power consumption for battery operated portable handheld devices.

CCS803
Product Overview
The CCS803 is an ultra-low power MOX gas sensor for monitoring Ethanol.
The sensitivity of CCS803 to Ethanol is optimised by adapting the supply voltage (VH) of 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 pulsedPWM mode to reduce power consumption. The sensor resistance (Rs) is determined using a series load resistor (RL), a reference voltage (VREF), and an output voltage (VOUT) read by an Analogue-to-Digital Converter (ADC).
