Take temperature readings and configure the settings of Calex PyroNFC infrared temperature sensors Save settings to your iOS device, and tap the PyroNFC sensor with the device to transmit them. Settings are saved to the sensor even if the sensor is not powered. With the sensor powered, take the measured temperature by touching it with your NFC device. Configurable parameters: - Select units: °C/°F - Linear voltage output range (0-5/1-5/0-10 V DC) - Temperature range for voltage output - Alarm output threshold and hysteresis - Emissivity setting - Reflected temperature - Averaging period - Peak / valley hold mode - Hold period

About

Decibel Meter Noise Detector

This tool measures ambient noise levels in decibels (dB) in real-time. It allows users to record audio, capture photos with decibel data, and view historical noise level changes. Reports can be generated and exported for reference.

Highlights
  • Real-time decibel detection
  • Audio recording with peak decibel marking
  • Multimedia evidence collection with watermarks
  • Real-time chart display of noise changes
  • Historical decibel record viewing
  • Data detection report export

The decibel tester is a professional noise decibel detection software, also known as a decibel measuring instrument, decibel meter, noise detector, etc. It can help you detect the decibel (dB) of the surrounding environment in real time, allowing you to understand the noise situation of the surrounding environment at any time, easily measure the current noise level of the environment, record the decibel change value, capture the surrounding environment, and record the noise. Easy to operate and convenient to use. [Functional Features]: 1. Real time decibel detection: Measure the decibel value (dB) of the current environment's noise, synchronously record audio and mark the peak decibel value, and save the generated timestamp record. 2. Multimedia evidence collection: Record decibel data watermarks during photo and video evidence collection, with a complete and traceable evidence chain, and support for adding evidence collection information such as geographic location and time. 3. Real time chart display: The chart displays real-time changes in noise decibels and provides reference for noise standards. 4. Historical record viewing: Record the decibel level of each detected noise, making it convenient for you to view the detection history. 5. Test result export: One click generation of data detection report, supports exporting and saving to local. Usage tips: The values obtained by the decibel meter are for user reference and simple recording only. The noise value results come from the user's native mobile phone microphone, and the microphone of mobile devices has certain limitations in recording, so obtaining values cannot replace professional noise instruments.
