The interesting part of these cameras are the PIRs, the passive infrared sensors. They work by monitoring the temperature in front of the device: When a change is detected, the sensor can trigger ...

The passive infrared (PIR) sensor market is experiencing significant growth as demand for efficient motion detection and ...

Three passive infrared sensors on the Wyze Cam Floodlight offer up to 270 degrees of motion detection. You can turn the individual PIR sensors on or off, as well as adjust their range and ...

Dr. Altepeter and DARPA hope to begin to do that by investigating the basic science necessary to give unmanned vehicles entirely passive infrared sensors to navigate.

Of course, when talking temperature sensing, it's also about range and accuracy. The TMP006 operates from -40 to +125°C, with typical accuracy of ±1°C for the passive IR sensor and ±0.5°C for the ...
