Does anyone have recommendations for BLE battery powered sensors that have a fast temperature response time. |

All sensors respond quickly to changes but reach their final temperature slowly. The simplest and fastest temperature sensor is a bolometer. Built on an ultra-thin wire, such as tungsten, enclosed in a vacuum tube, it works by detecting thermal radiation and changing its resistance. The thinner the wire, the faster it changes temperature and, consequently, its electrical resistance. |

This is due to the time it takes for the surrounding mass and the housing's thermal insulation to warm up.
Use an external sensor.
The sensor polling interval can be reduced to less than a second by decreasing the beacon transmission interval. However, this increases battery consumption.
