Moderately priced Passive Infrared PIR Sensor modules are now widely available. By using these readymade and pre-configured PIR sensors, even an average electronics hobbyist can construct his/her own ...

In the microcontroller era today, Arduino is more than just a tool to accomplish hobby tasks. There is actually a close relationship between microcontroller technology and home security, since you can ...

Wireless data transmission enables many applications (e.g., in the field of home automation). However, the communication must be robust and reliable. This nRF24L01+-based PIR sensor project is a basic ...

The LS6506R is a pyroelectric infrared (PIR) sensor interface IC that is designed to drive a latching relay. However, the device can be used in a wall-switch configuration (no Neutral available) to ...

The system is intended to support multiple transmitter/sensor units in an 'offline' (non-infrastructure) mode in case of remote usage. Think: camping. Don't want no bears sneaking up on me know what ...

A simulation project that detects intruders using a PIR sensor and sends a captured image via email with a alert beep. Built using Proteus, a microcontroller, and opencv. Useful for learning embedded ...
