Sleep Mode on Grove - Laser PM2.5 Dust Sensor - Arduino Compatible - HM3301

Does anybody know the command to put the HM3301 into and out of sleep mode, I only need measurements every 15 minutes to half an hour and would like to avoid running the fan continuously. The datasheet only seems to show for serial instead of I2C. A more complete datasheet of the actual laser module might contain the necessary information, I am unable to locate one though. I know I can just switch power to turn it off/on, but sleep mode would be preferred.

Thanks,
Greg

There is a SET pin to enter sleep mode.

thanks, works perfectly
