Oddly Specific Objects Sensor Watches Lite & Pro
Oddly Specific Objects Sensor Watches Lite and Pro utilize the capabilities of an ultra-low-power Arm® Cortex® M0+ microcontroller upgrade for Casio F-91W or A158W watches. These sensor watches include a small circuit, less than an inch in diameter, and feature a 100mAh single-coin cell battery. The sensor watches Pro and Lite use a monochrome segment LCD on the Casio F-91W and A158W for an always-on display that consumes less power. The sensor watch Pro features an RGB LED, an infrared light sensor, a voltage boost for the piezo buzzer for extra volume, and a soldering-free installation experience. Additional features of Sensor Lite include clock, moon phase, backpacker, stargazer, athlete, sunrise/sunset, and world clock. Additional features of Sensor Pro include day/night percentage, menstrual cycle, interval timer, tarot, wordle, couch to 5K, TOTP, countdown, advanced alarm, and simple calculator.
