Synchronization of events in iot devices

A method, comprising:

• receiving, at one or more Internet of Things (IoT) devices, respective measurement configurations that synchronize respective sensor measurements captured by the one or more IoT devices according to an absolute time reference, wherein the respective measurement configurations comprise:
• a configuration period;
• a measurement period;
• and
• a transmit period;
• capturing, by the one or more IoT devices, the respective sensor measurements according to the absolute time reference, comprising:
• executing configuration instructions within the configuration period to prepare the one or more IoT devices to capture the sensor measurement;
• executing measurement capture instructions to capture the sensor measurement, starting at a measurement start time determined based on the absolute time reference and the configuration period;
• and
• wirelessly transmitting the sensor measurement to a recipient device within the transmit period.

One or more non-transitory, computer-readable storage media, storing program instructions that when executed on or across one or more computing devices cause the one or more computing devices to implement an Internet of Things (IoT) device that implements:

• receiving a measurement configuration that synchronizes respective sensor measurements captured by a plurality of IoT devices, including the IoT device, according to an absolute time reference, wherein the measurement configuration comprises:
• a configuration period;
• a measurement period;
• and
• a transmit period;
• capturing a sensor measurement according to the absolute time reference, wherein in capturing the sensor measurement, the program instructions cause the IoT device to implement:
• executing configuration instructions within the configuration period to prepare the IoT device to capture the sensor measurement;
• executing measurement capture instructions to capture the sensor measurement, starting at a measurement start time determined based on the absolute time reference and the configuration period;
• and
• wirelessly transmitting the sensor measurement to a recipient device within the transmit period.
