Abstract
Systems and methods described herein reduce contention on shared buses through which multiple sensors send sensor readings to a computing destination by allowing different query rates for each sensor and dynamically adjusting the query rate for each sensor based on the readings that sensor reports. A first query is sent to a sensor via a bus to request a current sensor reading from the sensor. In response to the first query, the sensor sends the current sensor reading via a bus. A function of the current sensor reading, a predefined time range, and a predefined reading-value range is evaluated to determine a time interval between the first query and a second query to be sent to the sensor. When the amount of time elapsed since the first query was sent matches the time interval, the second query is sent to the sensor via the bus to request an updated sensor reading.
