Web alarm clock for 2:22 p.m.
Before handing over the farm check, set the alarm for 2:22 pm so the next person knows exactly when to inspect the rain gauge. That gives them a clear point in the shift to record the level, note any fresh rainfall, and pass on the reading before 3:00 pm. Agree beforehand where the measurement will be written, so it does not disappear between one person leaving and another taking over.
Because the rain-gauge check is changing hands, keep this alarm page open while the reminder is pending and leave the phone or computer awake. If you close the page or browser, or let the device sleep, the rain-gauge alarm may not sound, leaving the incoming person without the agreed cue. Turn up the volume enough to be heard from the work area, then confirm that the displayed alarm time still reads 2:22 pm.
For a midday rain-gauge reading, harsh Philippine sunlight can make the water line and scale difficult to distinguish, especially on a clear container. Arrange the handover near open shade, or position yourself so your body blocks glare without darkening the markings. If clouds are building, keep a small torch ready before walking out; steady side lighting can make the gauge marks easier to read while preserving the scheduled 2:22 pm observation.
