Market Development Pyroelectric infrared (PIR) sensor technology has been one of the fastest-developing technologies in recent years.

The essentially digital nature of LED lighting has greatly enhanced controllability, which can be used to achieve a wide variety of lighting effects, from dimming and colour‑changing to ...

Researchers designed an IoT network using sound and motion sensors that estimates public space utilization. The ideas can be applied to other IoT sensor networks.

In this security system is based on the embedded system along with GSM and sensor networks. The human movement is detected using the PIR sensors.
