Web alarm clock for 2:25 p.m.
Once you have finished checking the farm rain gauge, set this 2:25 pm alarm before you pack the reading away and leave the field. It gives you a clear signal to wrap up without repeatedly checking your phone. If another small farm task needs attention, the remaining stretch before 3:00 pm leaves room to handle it without losing track of your departure.
Your rain gauge check could be missed if the alarm sound quietly routes to headphones left in a pocket, bag, or farmhouse room. Confirm where your phone or computer is sending audio, then choose a level you can hear from beside the gauge. Keep the alarm page active and the device awake: if either is shut down, no alert will sound to mark the rain gauge reading or your planned exit.
Leaving the farm at 2:25 pm can preserve a useful part of the afternoon for rest before evening responsibilities. Once the reading is recorded, put away the measuring notes and avoid turning the next 35 minutes into a string of extra chores. In the Philippines, where midday heat or a sudden shower can make fieldwork tiring, a quiet break indoors may help keep that remaining rest from disappearing.
