## Examples
### Is the temperature rising or falling
The hysteresis parameter can be used in this use-case to avoid frequent state changes around the maximum or the minimum of a temperature curve. We also have to utilize the [derivative sensor](/integrations/derivative/) for this use-case:
```yaml
sensor:
- platform: derivative # will be positive for rising temperatures and negative for falling temperatures
source: sensor.temperature
unit_time: min
name: temperature derivative
time_window: 00:05:00
binary_sensor:
- platform: threshold # will switch state not at 0°C/min but 0.1°C/min or -0.1°C/min depending on the current state of the sensor, respectively
entity_id: sensor.temperature_derivative
upper: 0
hysteresis: 0.1 # sensor
name: temperature rising
```
