These sensors use infrared, radar, and sound waves to detect changes that mean someone or something is in the space. Use cases: If someone passes into the hallway, turn on a light.

Researchers have finally figured out how mosquitoes see humans in the dark: They detect infrared light the body generates via heat.

IR blasters are hardware components and cannot be installed or downloaded. If your smartphone does not have an IR blaster, you need to use an external IR blaster device.

In fact, if you removed the sensor, you could reuse it and connect it to the IR transmitter. It wasn’t clear how you could easily package the RF transmitter and the remote.
