Smart Phone Sensor Checker

Before you build an app or a device, check whether the phone can actually produce the signals it will depend on. A spec sheet may list a sensor, but whether it reports values, how often, and how accurately varies from handset to handset. Sensor Checker shows you. ■ Two ways to use it Situations - pick one of ten situations (on a boat, coastal walking, work at height and more) and the required sensors and sampling rate are set for you. You see at a glance whether this phone is enough for an app built around that situation. Single sensor - turn on any of 18 sensors one at a time and watch its value and waveform. Nothing is recorded, so you can explore freely. ■ Display that fits the sensor Heading appears as a compass, tilt as a spirit level, cellular strength as signal bars, position on a map. Not just rows of numbers. ■ Signals you can check Location - latitude/longitude, altitude, accuracy, speed, satellite count Cellular - signal strength (dBm), bar level Motion - acceleration, linear acceleration, gravity, gyroscope Attitude - heading, pitch and roll, magnetometer Environment - barometric pressure, relative altitude, light, proximity ■ Export to Excel Save a session as an xlsx file. Alongside the raw values it includes a sheet explaining every column, its unit, and the grading thresholds, so whoever receives it can read it without asking you. ■ Your data never leaves the device Measurements are stored only on this phone. Nothing is uploaded. No accounts, no ads, no analytics SDKs. ■ Four languages Korean, English, Chinese and Japanese. Switch any time inside the app; the Excel export follows the language you chose. ■ Not a safety device This app does not detect or report accidents. It is a development and evaluation tool for checking what signals a handset can produce. Do not rely on it where safety is at stake.
