The Sensors tag collects articles about the various electronic sensors found in modern phones, smartwatches, and connected devices. This page is for anyone who owns a wearable, a smartphone, or a smart home gadget and wants to understand, test, or fix the sensors inside them. Whether you are troubleshooting a device or simply learning what a specific sensor does, these articles provide clear, practical guidance.
The articles address three main kinds of problems. First, several pieces help you configure or disable sensors that are causing annoyance or confusion, such as how to turn off the green light on a Fitbit or how to enable the proximity sensor on a OnePlus Nord. Second, a group of articles focuses on understanding and testing sensor data, including how to test an O2 sensor with live data and what an EDA scan on a Fitbit actually measures. Third, there are articles about choosing and placing devices based on their sensors, like learning which wrist to wear your smartwatch on or finding out what cheap phones have a gyroscope.
Specific topics covered include adding a wireless sensor to an ADT alarm system and the emerging technology of electronic textiles, or e-textiles. By reading these articles, you will learn how to adjust sensor settings on your phone and watch, how to interpret the data your sensors produce, and how to make informed decisions when buying or placing sensor-equipped devices.
