Gorillacell Module 022: PIR Sensor

The PIR (Passive Infrared) Sensor detects motion by sensing infrared radiation emitted by heat-producing bodies such as humans and animals. It is commonly used in motion-activated lighting, intruder alarms, and automatic security systems.

The Gorillacell ESP32 Development Kit includes one (1) PIR Sensor module, allowing users to experiment with motion detection and security-related projects.

It also comes with a slide switch for selecting between single trigger and repeated trigger.

1. Repeatable

   - repeated trigger.

2. non-repeatable

   - single trigger.

BASIC INFORMATION

PINOUT

It has 3 pins which are

1. G - for the ground pin,
2. V - for the supply voltage, and
3. S - for determining the state of the PIR Sensor module.

A PIR Sensor produces a logic 1 when it detects a living organism else it is logic 0.
