# PMS Passive Sleep Example
This example demonstrates using the PMS sensor in passive mode, with data being streamed only after the sensor receives a *passive mode read commmand*.
Sensor will be put into passive mode with a *set mode command* sent over UART. Example will log the state of the sensor that is currently in every 3 seconds. It will read one data frame once the sensor reaches active state, it wil parse the data, print the PM concentration and put the sensor to sleep for 5 seconds. This cycle runs indefinitely.
This example can be done without connecting any control pins (SET and/or RESET pins).
## Recommended hardware setup
