Selection reference · illustrative scenario
Clock roles in the application
Environmental sensing, irrigation control and gateways need separate acquisition, actuator, wireless and sleep-timing requirements matched to field power.
Engineering selection review
Review wake-timing error, host start-up, wireless references and outdoor temperature. Compare battery or solar designs using their actual duty cycle.
Procurement and documentation
Include host, sensors and wireless module and sampling and wake cycles, plus the existing full code, sample and production quantities and delivery target. Discuss nominated international brands and domestic candidates separately, confirming parameters and documents by part.
Illustrative validation scenario
Simulate scheduled wake, sensing, upload and recovery while logging time and power across temperature, without inferring field service life from a component alone.
