Numerous connection inputs/outputs allow for the implementation of different kinds of buses and interfaces to sensors, actuators and external communication modems.
These functional components allow us to develop a number of low-power IoT protocols carrying the “streams” of IoT data. Here we distinguish several operational cycles based on two power consumption stages: high_power (~ 50mA) and low_power stages (~ 20µA).
Two power reduction mechanisms
As-long-as-possible Low Power stage
The High Power stage is built from several phases (initialization, sensing, processing, transmission, reception).
To-send or Not-to-send decision
The consumption of the transmission phase is several times higher than that of the other phases.
The proposed low-power IoT protocols operate with the control of these two power reduction mechanisms via several parameters such as:
Cycle Time
Implying the low_power stage time.
Delta
Indicating minimum distance between last send and current sensor(s) value.
Low/High Thresholds
Indicating urgent transmission events.
kpack
Indicate when to force the transmission phase (after numerous cycles without transmission).
Effective use of the power reduction mechanisms allows us to build IoT protocols with low (<1mA) or even very low (<100µA) average power (current) consumption.
Practical Session
We begin with a demonstration of two operational cases using independent IoT DevKits (plus a PC):
Directly Connected Terminal Demo
The first one deals with the power consumption of a directly connected terminal (WiFi) sending the sensor data to the IoT server.
Remotely Connected Terminal Demo
The second deals with the power consumption of a remotely connected terminal (LoRa) sending the sensor data to the IoT server via a LoRa-WiFi gateway.
Hands-On
Finally we use integrated IoT DevKits including: (1) x86 (N100), (2) ARM (RK3588), and (3) RISC-V (X1/K1) SBC boards. The SBCs of all integrated IoT DevKits provide the same µPython IDE and we use the same examples as above.
