Rice Harvest Monitor: Field-by-Field Harvest Timing by Accumulated Temperature
The best harvest day is a moving target that changes field to field. The OT300 mounts in the paddy and continuously accumulates temperature after earing, so you harvest each field at its own optimal window instead of guessing from a single calendar date.
Field-by-field timing: tracks up to four fields independently, each from its own earing date, so adjacent fields can be harvested on their own schedule.
Clear readiness stages: on-screen READY, OK, and LATE marks flag the approach, the optimal window, and the overdue point at a glance.
Unattended in the field: pole-mounted in a weather shelter and battery-powered, it monitors continuously with no daily handling.
Memory-safe power: dual 9V battery design lets you swap a dead battery without losing accumulated data.
