Notes:
1. When VH is produced by PWM of a VDD above 1.8V the duty cycle (%) must not exceed 1.8V2 / VDD2
2. Based on a sensor measurement duty cycle of 2.5%, heater ON for 1.5secs (0.5s @ 1.6V, 1s @ 1.4V)
and then heater OFF for 58.5s (0V).
Sensor Performance
Sensitivity is defined as the sensor’s resistance in air (Ra) divided by the sensor’s resistance at a specific gas
concentration level at 50% relative humidity and 25°C ambient temperature (Rg). The following chart shows
the sensitivity of CCS801 to CO, Ethanol and Toluene (as an example VOC gas) in constant power mode with a
heater voltage (VH) of 1.4V.
Operating a new sensor in constant power mode at VH in the first 24 hours is recommended to ensure sensor
performance is stabilised.
