HPS-100
Automotive Hydrogen Sensor
General Description
The HPS-100 is an automotive hydrogen sensor that monitors
hydrogen concentrations of 0 – 100 Vol%. The design fulfills
Zone 2 requirements according to ATEX 100a. The predicted
concentration is transmitted to the host via the CAN bus
interface or PWM.
Ordering Information and Content Guide appear at end of
datasheet.
