Prometheus Sensors

This is a library that implements a set of sensor types, reading their values periodically and exposing them to Prometheus using the prometheus-metrics library.

Supported Sensors

DHT

This is using dht library; each sensor reading takes approximately 32ms (28ms if there is no sensor on the GPIO in). They are placed on timers so as to minimize pre-emption of the main application. DHT sensors are polled in order based on sensors.dht_gpio pins and with a period of sensors.dht_period which defaults to 3 seconds.
