- * @param max_error - Maximum error threshold; program will exit if this is exceeded for the sensor reading
- * @param min_error - Minimum error threshold; program will exit if the sensor reading falls below this value
- * @param max_warn - Maximum warning threshold; program will log warnings if the value exceeds this threshold
- * @param min_warn - Minimum warning threshold; program will log warnings if the value falls below this threshold
+ * @param cleanup - Function to call whenever to deinitialise the sensor (may be NULL)
+ * @param sanity - Function to call to check that the sensor value is sane (may be NULL)
